Essay on Functionalism in Education - 1134 Words

Having attended public schools throughout my childhood and adolescence, I never was familiar with the term functionalism and its many elements. After observing and analyzing my field placement classroom I have come to understand the concept of functionalism to some extent. In general, functionalists â€Å"see schools as serving to socialize students to adapt to the economic, political, and social institutions of that society† (Feinberg, p.6, 2004). They also theorize that in order for societies to survive, they must carry out vital functions such as, attaining fundamental knowledge and acquiring essential skills and proficiency, acknowledging certain norms and values within their community, and recognizing authority figures. It is also†¦show more content†¦As soon as their teacher, Mrs. Root asked them to settle down, they instantly became silent. This is an example of an unspoken expectation of the teacher and is one of many hidden curriculums that I witnessed in the classroom. Another instance was during instruction; Mrs. Root had asked a question pertaining to shapes and who ever knew the answer, demonstrated this particular hidden curriculum by raising their hand. The functionalist concept, hidden curriculum, is best defined as â€Å"organizational features and routines of school life that provide the structure needed to develop the psychological dispositions appropriate for work and citizenship in industrial society† (Feinberg, p. 21, 2004). It is intended to assist in achieving norms, learning one’s position in society, and how to think of oneself. Hidden curriculum has also been explained as making the transition from family to the real world less difficult. This concept applies to the examples I gave because when the teacher asked the students to settle down, they instantly knew that they needed to follow directions. The idea that teachers are authority figures and deserve to be respected is instilled in children at a very young age and is expected to be upheld. As for students raising their hands when wanting to speak or answer a question, this has also been implanted in children’s minds and is a norm in today’s society.

Black Panther Party Research Essay Research Paper free essay sample

Black Panther Party Research Essay, Research Paper Guns, Social Welfare, and Revolution: The Black Panther Party In late September of 1966, at a little poorness centre in North Oakland, Huey P. Newton and Bobby Seale began to outline the Ten-Point Platform and Program, therefore making the Black Panther Party for Self Defense. From this creative activity rose a complex patriot organisation with chapters throughout the United States that sought to educate the people politically, and from that instruction give the people the desire to ramp a revolution in order to hold their demands and political docket fulfilled. The Black Panther Party was the prototype of the patriot option throughout the late sixties and 70s, and they had the demand to make alteration within what they believed to be the racist power construction of the United States. The Black Panther Party was able to form the people, and take portion in actions that would assist to implement societal alteration. The Panthers created timeserving plans for the Black young person in order to assist construct up the community. In add-on, the Panthers besides staged many presentations and protests that non merely brought together the Black community, but besides benefited the cause of equal rights. Despite all of the good facets that the Black Panther Party brought to the Black community and civil rights motion ( or possibly because of these facets ) , the F.B.I. and United States authorities believed the Panthers to be one of the United States greatest internal jobs. In hindsight, it becomes obvious that the US power construction was flawed in their apprehension of the Black Panther Party and their ends. Yet, in malice of this misinterpretation, the Black Panther Party was able to somewhat forestall the authorities s flawed manner of analyzing political groups to predominate into the hereafter by agencies of the Panther s bequest. The Black Panther Party was created on the belief that the Unite d States was structurally racist, and that this racism was trying to genocide the Black race. The Black Panther Party believed that to antagonize this racism, they needed to destruct the power construction, and replace it with a merely system of authorities. Racism was non merely some self-conceived impression taken up among the members of the Black Panther Party. Racism had been happening in America by agencies of the slave trade even before the United States was called the United States. With the terminal of bondage, it was expected that Blacks would be able to incorporate into the remainder of American society and be provided with the warrants of all work forces populating in the United States as determined by the Constitution. However, it was non expected that the white community would be as opposed to this alteration as they were. The ultimate signifier of racism was portrayed in the White supremacist group the Ku Klux Klan. This group terrorized Black people throughout the South, every bit good as any sympathisers of the Black battle. In 1930 Dr. Arthur Raper was commissioned to bring forth a study on lynching, at the clip a much excessively frequent pattern in the South. He discovered that there were 3,724 people reported lynches in the United States from 1889 through to 1930. Over four-fifths of the peopled that were lynched were Negroes, and less than one-sixth of whom were accused of colza. Practically all of the lynchers were Whites. Of the 10s of 1000s of lynchers and looker-ons, merely 49 were indicted and merely 4 have been sentenced. In 1935 President Franklin D. Roosevelt refused to back up an anti-lynching measure because he argued that the white electors in the South would neer forgive him and decline to vote for him at the following election. The tolerance that the constabulary and the authorities had for lynching showed the disregard of the President and Congress in doing appropriate statute law and implementing that statute law to halt the pattern of lynching. As the laden began to contend back against the oppressors throughout the Civil Rights motion, the pattern of lynching began to slowly lessening, nevertheless, the force against Blacks persisted. Thirty old ages after Dr. Raper s study on lynches, rabble force and constabulary ferociousness against Blacks still occurred on a regular basis in the United States ; the authorities was still non looking out for Black Americans. In 1966, police ferociousness was a job in many countries of the state. The freshly formed Black Panther Party for Self Defense sent a strong message in turn toing this job: they wanted constabularies ferociousness to halt, and to make this they proposed the maneuver of self-defence. The thought of self-defense, along with the group s chauvinistic positions is portrayed in the Black Panther Party s ten-point plan. The Ten-Point Program was based on simplenesss that any citizen of the United States would want. Composed by Huey Newton and Bobby Seale, the Ten-Point Program became a cardinal constituent in the organisation of the group. The plan stresses freedom for those who were being oppressed, and an terminal to the inhibitory authorities. The Program besides strongly advocated the usage of guns for self-defence and stressed the 2nd Amendment. With 1000s of transcripts of the Ten-Point Program in manus, Newton, Seale, and Bobby Hutton went throughout the Black community jointing the Program to the people, garnering support. The three so went on to put up the 1st official central office of the Black Panther Party in North Oakland. After the creative activity of this office in Northern Oakland, involvement in the Black Panther Party began to increase throughout Oakland ; subsequently this involvement spread on a national degree, with chapters in 48 provinces, and a few international chapters every bit good. The Black Panther Party was in all facets of the term, a nationalist group. The Panthers felt that the authorities was incapable of supplying a merely authorities for all work forces, peculiarly Black work forces, and that the authorities should be replaced with a system that could see justness. The Black Panther Party s Ten-Point Program accurately inside informations this end. The Ten-Point Program was a basic desire for Black America to acquire what White America was granted without inquiry, and what Black America had been deprived of. The Programs demands were simple: freedom to find the fate of Black communities, full employment, an terminal to development of Black communities by Capitalists, nice lodging, wellness attention, an terminal to patrol ferociousness, an terminal to war, and tests for Blacks with a Black jury as opposed to an all White jury. To be granted these demands, the Ten-Point Program provinces, it is their [ the Black community s ] right, it is their responsib ility, to throw off such authorities, and to supply new guards for their future security. The Ten-Point Program and Platform boldly called for an overthrow of the authorities, and encouraged people to take up weaponries to protect themselves against these fascist constabulary forces. The Panther s were recommending radical alteration, and the people were listening. One of the grounds that the Black Panther Party was able to garner and keep so much support throughout the Black community was because they were genuinely concerned with breaking the community. Before the sta rt of the party, Huey Newton and Bobby Seale were both involved in the North Oakland Neighborhood Anti-Poverty Center. At this centre Newton was a community organiser, while Seale was the chief of a young person work undertaking. This experience in working with the community doubtless helps to explicate why most of the societal plans that the Black Panther Party developed were so successful. The plans created by the Black Panther Party, which were operated by Party members, were referred to as SPR or survival pending revolution. The first such plan was the Free Breakfast for Children Program. At its tallness, the plan was a immense success, feeding 200,000 kids daily. The plan started in a Catholic church in the Fillmore territory of San Francisco, so spread to every major metropolis in America where there was a Party chapter. Other societal services that the Black Panther Party began to supply were free wellness clinics, food market giveaways, the fabrication and distribution of fre e places, school and instruction plans, senior conveyance and service plans, free bussing to prisons and prisoner support plans, and legal assistance plans, among many others. For the most portion, these plans were all successful in supplying Blacks and other minorities with much needed societal services. Some plans were so successful, such as the Free Breakfast for Children Program, that the authorities was forced to follow similar plans throughout the state. Peoples within Black and White Communities began to recognize that the Black Panther Party was more than a clump of Black work forces with guns ; people began to recognize that the Black Panther Party could supply some replies to jobs within the community. Despite being criticized by the FBI as transporting out a Communist docket with SPR, the Black Panther Party was able to set together over 35 societal plans for the improvement of the community. Not merely was the Black Panther Party was able to supply many societal benefits for the community ; the Black Panther Party was besides highly active in the Black political battle and release motion. The Panther s called for an terminal to subjugation and offered revolution as an option. They were able to politically educate and form immature Blacks who were willing to contend for the party. In Oakland, the Black Panther Party invariably patrolled the hogs with guns in an effort to forestall constabulary ferociousness. The Panthers educated themselves on every gun jurisprudence on the books and were able to avoid being arrested in most instances ; nevertheless, in some cases, members of the Black Panther Party were arrested merely for the fact that they were Black work forces with guns. A polar event for the Black Panther Party occurred due to patrol over exerting their power and hassling Huey P. Newton and Bobby Hutton because they had guns. The result of Newton and Hutton s confro ntation with the constabulary left Hutton and a police officer dead, and landed Newton behind bars for manslaughter. The resulting Free Huey motion brought together the community every bit much as any other action that the Black Panthers took portion in. Young Whites, angry at America over the Vietnam War, joined immature urban Blacks in mass meetings to intone in unison: Free Huey! The laden combat back against his oppressors was a message that any adult male, Black or White, could appreciate. The will of the people in their battle to liberate Huey was able to assist Huey Newton acquire out of gaol three old ages after his apprehension, acquitted of all charges. Another case when the Black Panther s used their power to act upon political relations was when a group of Black Panthers, led by Bobby Seale, stormed into the California State Legislature to protest a gun-control measure. The group delivered their message to the legislative assembly, and was subsequently arrested in path b ack to Oakland. All of the members arrested spent a short clip in gaol for upseting the peace, but were neer convicted of any offense. The fact of the affair was that the Black Panther Party made their political voice heard. Despite being arrested and imprisoned, the message that the Panther s were seeking to acquire across was heard, and there was no manner that the White power construction could halt it. With the formation of the Black Panther Party and their chauvinistic positions within Ten-Point Program and Platform, the Black Panther Party had an enemy. The group that opposed the Black Panther Party the most was the F.B.I. The F.B.I. Director, J. Edgar Hoover, called the Black Panther Party the greatest menace to the internal security of the U.S. The F.B.I. viewed the formation of societal plans by the Black Panther Party as forcing a Communist docket. Alternatively of dissecting the message that the Black Panther Party was seeking to acquire across, the power construction could merely see Black work forces with guns. The F.B.I. made it a end to stop the organisation of the Black Panther Party in 1969. The most utile arm that the F.B.I. had in their armory to destruct the Black Panther Party was a counterintelligence plan competently name COINTELPRO. Through the usage of this plan the F.B.I. was able to destruct the party by agencies of its field offices and the aid of local cons tabulary. These bureaus frequently were involved in covert activities that involved slaying and mayhem. With the slayings and apprehensions of much of the hierarchy of the Black Panther organisation, the party began to easy demise throughout the seventies. A brief resurgence occurred in 1977 when Huey Newton returned to Oakland after several old ages of expatriate, but internal struggle within the party and continued F.B.I. activities brought the Party to an about nonexistent province by the 1980s. The Black Panther Party was founded on the thought that the power construction of the United States was racialist, and that it needed to be replaced. In trying to accomplish this end of revolution, the Panthers were able to construct up the community to convey people together, and allow their voice be heard. Many of the societal plans that the Panthers implemented have survived into the present twenty-four hours. Despite the best attempts of the F.B.I. to destruct the Jaguars and their ideals, the Panthers bequest of Black political power and community service will populate on forever.

Responsible Government In The Canadian Regime Essay

Responsible Government In The Canadian Regime - Essay Example Soon, people began to agitate and rebel seeking "reform" of the constitutional system. As a result, Lord Durham was sent to Canada to investigate the cause of the rebellions and to figure out a solution. Lord Durham stressed that "the complete assimilation of French Canadians" (Malcomson and Myers 2005) was necessary and proposed the Act of Union. Further, he stated that a responsible government was needed to handle the situation and the British Government eventually acknowledged the idea. Canada's constitution has therefore been under the principle of responsible government, based on the fusion of power, which is distinct from a separation of powers. This fusion of power is the most important and fundamental factor in the responsible government system that helps the Canadian government remarkably efficient. It also increase voters' accountability, and imposes strong influence over the confidence in the House of Commons. The responsible government which depends on the fusion of power, allows the cabinet not only to acts as an executive but also to take a role in legislative action. There are no "standstills of the sort[and] once the cabinet backed by a parliamentary majoritythere is nothing to stand in its way." (Malcomson and Myers 2005) Because the same group is responsible for legislating, practicing and enforcing the law, they can take decisions without transferring the proposal from one branch to another for permission. Moreover, in a responsible government, the "power is married to responsibility". (Kam, Sept 19, 2006) Under separation of powers, it is hard to blame a particular branch or a person for unsatisfactory political events. However, in a responsible government, the power is fused into one system, and therefore, the responsibility for positive or negative events lies on one entity alone. This also influences the voters' evaluation of their elected servants. The fusion of power increases the accountability to the voters much more than separation of powers. Under the principles of responsible government, the prime minister and the cabinet's legitimacy solely depend on the confidence of the House of Commons which generates unique characteristics for the government. The prime minister and the cabinet are not directly elected by the people. Because of this, their democratic legitimacy depends on the confidence of the House of Commons. Consequently, if the members of the party do no support each other and cooperate in order to endorse the ministry, they will soon lose the confidence of the House and their right to rule would be taken away. For this reason, the party discipline in Canada is pretty strong. Furthermore, it prompts MPs to vote in support of their party instead of their constituents' desires. The dependence on the confidence of the House of Commons also influences the date of the election in Canada. Under the principle of separation of powers, each branch and the president are elected separately. Once they are elected, they each have their own mandate. However, in Canada, "the timing of parliamentary elections is normally decided by the prime minister". They "canlose that confidence at anytime,[so] it is essential to be able to hold elections at any time." (Malcomson and Myers 2005) The responsible government system originated from the British, but soon percolated into the Canadian government, creating distinctive features in the

Edvard Munch Research Paper Example | Topics and Well Written Essays - 250 words

Edvard Munch - Research Paper Example His paintings reflect his tragedies and failures that transcribe the reality and record the impact of a personal experience. These pieces of art transmit emotional sensation as a result of the natural contemporary issues. The visionary power is enhanced by the incorporation of the lyrical and romantic aspects in his work. Munch was concerned with expressing humanity and consciousness in art by incorporating the injustices and relationships experienced by living people. The â€Å"Frieze of Life† has the sensation of love between men and women that is a force of nature (20). The painting has a narrative of awakening love that blossoms and withers, and ends with despair and death. The â€Å"Kiss† also depicts a woman and man locked in a passionate embrace. These paintings reflect the reconstituted subjectivity of the natural world where people experience love naturally and the feeling is shattered by death. Love, death, suffering, and illnesses are aspects of the current society illustrated in the work of Munch. The ability to intertwine reality and art has gained Munch popularity in modern

Business and The Law - Promisory Estoppel(case of Central London Essay

Business and The Law - Promisory Estoppel(case of Central London Property Trust Ltd v High Trees House Ltd - AND -Golfing Case - - Essay Example However, Lord Denning went on to state that the promise could nevertheless be enforced with respect to the war period because the: Promise to accept a smaller sum in discharge of a larger sum, if acted upon, is binding notwithstanding the absence of consideration: and if the fusion of law and equity leads to this result, so much the better. 5 Thus, the ruling in the High Trees case not only provided an exception to the Foakes v Beer case, but also to Pinnel’s Case which was affirmed by Foakes v Beer. ... Lord Denning then defined the parameters for the High Trees doctrine: The principle stated in the High Trees case...does not create a new cause of action where none existed before. It only prevents a party from insisting upon his strict legal rights, when it would be unjust to allow him to enforce them.7 What can be gleaned from the ruling in High Trees and Lord Denning’s explanation of the ruling in Combes, is that promissory estoppels permits a defence of detrimental reliance in the UK for the purpose of suspending a previous commitment. However, it will not be available as a defence in respect of a new action where consideration does not exist. Put another way, the High Trees significance is that it accommodates a detrimental reliance defence for suspending previous contractual commitments. The ruling in High Trees was adopted by the Supreme Court of South Australia in Je Maintiendrai Pty. Ltd. v Quaglia [1980] 26 SASR 101. In this case, the court held that in order for the doctrine of promissory estoppel to succeed it must be shown that the promise could or would â€Å"result in some detriment and therefore some injustice† to the complainant.8 Clearly, the High Trees case opened up a method by which the doctrine of promissory estoppel could be used to prevent unconscionable avoidance of commitments. In Waltons Stores (interstate) Ltd v Maher (1988), another Australian case, the court took the High Trees doctrine a step further. In this case, the limitations to the use of the doctrine of promissory estoppel established by the High Trees case were both removed on the grounds of injustice. High Trees established that in order for a promissory estoppel defence to be successful there must be a pre-existing legal relationship between

Uses Of Starter Motors And Their History Engineering Essay

Uses Of Starter Motors And Their History Engineering Essay Motor Starters are switches specially designed for starting motors. These switches are designed to control the flow of current. There are basically two types of motor starters, Manual Starters and Magnetic Starters. Uses of STARTER In a Motor : 1: To give starting resistance to motor. 2:Starter is used to safe the motor winding from the high starting current. 3: Starter is used in a motor to control the limit of high starting current.As the motor starts(in case of DC motor) high current occurs which is controlled by use of high resistance slowly cut out of the circuit. History Both Otto cycle and Diesel cycle internal-combustion engines require the pistons which is used to convert pressure into motion. Originally, a hand crank(handle) was used to start engines, but it was difficult, and dangerous to start an engine. Even though cranks had an overrun mechanism, when the engine started, the crank could begin to spin along with the crankshaft and it might strike the person starting the engine. Care has to be taken to prevent the spark from backfiring. In short we can say that there is a lot of risk while starting the engine with a a crank.Moreover, increasingly larger engines with higher compression ratios made hand cranking a more physically demanding endeavour. While there was a need of starter, as in 1899, Clyde J. Coleman applied for U.S. Patent 745,157 for an electric automobile self-starter inventing one that worked successfully in most conditions did not occur until 1911 when Charles F. Kettering of Dayton Engineering Laboratories Company (DELCO) invented and filed for U.S. Patent 1,150,523 for the first useful electric starter. (Kettering had replaced the hand crank on NCRs cash registers with an electric motor five years earlier.) One aspect of the invention lay in the realization that a relatively small motor, driven with higher voltage and current than would be feasible for continuous operation, could deliver enough power to crank the engine for starting. At the voltage and current levels required, such a motor would burn out in a few minutes of continuous operation, but not during the few seconds needed to start the engine. The starters were first installed by Cadillac on production models in 1912. The Model T relied on hand cran ks until 1919; by 1920 most manufacturers included self-starters.The electric starter ensured that anyone could easily start and run an internal combustion engine car, and this made it the design of choice for car buyers from that day forward. Details about the Starters used-> Following starters used to operate motor starter Electric starter Gear reduction starter Pneumatic starter The Principal at which motor starter is worked Electric starter used in motor starter Electric starter Main Housing Overrunning clutch Armature Field coils Brushes Solenoid What is motor starter? A starter motor is a high-torque electric motor for turning the gear on the engine flywheel. The modern starter motor is either a permanent-magnet or a series-parallel wound direct current electric motor with a solenoid switch (similar to a relay) mounted on it. When current from the starting battery is applied to the solenoid, usually through a key-operated switch, it pushes out the drive pinion on the starter driveshaft and meshes the pinion with the ring gear on the flywheel of the engine. Before the advent of key-driven starters, most electric starters were actuated by foot-pressing a pedestal located on the floor, generally above the accelerator pedal. Solenoid The solenoid also closes high-current contacts for the starter motor, which begins to turn. Once the engine starts, the key-operated switch is opened, a spring in the solenoid assembly pulls the pinion gear away from the ring gear, and the starter motor stops. The starters pinion is clutched to its driveshaft through an overrunning sprag clutch which permits the pinion to transmit drive in only one direction. In this manner, drive is transmitted through the pinion to the flywheel ring gear, but if the pinion remains engaged (as for example because the operator fails to release the key as soon as the engine starts), the pinion will spin independently of its driveshaft. This prevents the engine driving the starter, for such backdrive would cause the starter to spin so fast as to fly apart. However, this sprag clutch arrangement would preclude the use of the starter as a generator if employed in hybrid scheme mentioned above; unless modifications are made. Also, a standard starter motor is only designed for intermittent use which would preclude its use as a generator. Overrunning clutch This overrunning-clutch pinion arrangement was phased into use beginning in the early 1960s; before that time, a Bendix drive was used. The Bendix system places the starter drive pinion on a helically-cut driveshaft. When the starter motor begins turning, the inertia of the drive pinion assembly causes it to ride forward on the helix and thus engage with the ring gear. When the engine starts, backdrive from the ring gear causes the drive pinion to exceed the rotative speed of the starter, at which point the drive pinion is forced back down the helical shaft and thus out of mesh with the ring gear. An intermediate development between the Bendix drive developed in the 1930s and the overrunning-clutch designs introduced in the 1960s was the Bendix Folo-Thru drive. The standard Bendix drive would disengage from the ring gear as soon as the engine fired, even if it did not continue to run. The Folo-Thru drive contains a latching mechanism and a set of flyweights in the body of the drive unit. When the starter motor begins turning and the drive unit is forced forward on the helical shaft by inertia, it is latched into the engaged position. Only once the drive unit is spun at a speed higher than that attained by the starter motor itself (i.e., it is backdriven by the running engine) will the flyweights pull radially outward, releasing the latch and permitting the overdriven drive unit to be spun out of engagement. In this manner, unwanted starter disengagement is avoided before a successful engine start. Starter used in motor starter : Gear-reduction starters Chrysler Corporation contributed materially to the modern development of the starter motor. In 1962, Chrysler introduced a starter incorporating a geartrain between the motor and the driveshaft. Rolls Royce had introduced a conceptually similar starter in 1946, but Chryslers was the first volume-production unit. The motor shaft has integrally-cut gear teeth forming a drive gear which mesh with a larger adjacent driven gear to provide a gear reduction ratio of 3.75:1. This permits the use of a higher-speed, lower-current, lighter and more compact motor assembly while increasing cranking torque. Variants of this starter design were used on most vehicles produced by Chrysler Corporation from 1962 through 1987. The Chrysler starter made a unique, readily identifiable sound when cranking the engine. This starter formed the design basis for the offset gear reduction starters now employed by about half the vehicles on the road, and the conceptual basis for virtually all of them. Many Japanese automakers phased in gear reduction starters in the 1970s and 1980s. Light aircraft engines also made extensive use of this kind of starter, because its light weight offered an advantage. Those starters not employing offset geartrains like the Chrysler unit generally employ planetary epicyclic geartrains instead. Direct-drive starters are almost entirely obsolete owing to their larger size, heavier weight and higher current requirements. Ford also issued a nonstandard starter, a direct-drive movable pole shoe design that provided cost reduction rather than electrical or mechanical benefits. This type of starter eliminated the solenoid, replacing it with a movable pole shoe and a separate starter relay. The Ford starter operated as follows: The operator closed the key-operated starting switch. A small electric current flowed through the starter relay coil, closing the contacts and sending a large current to the starter motor assembly. One of the pole shoes, hinged at the front, linked to the starter drive, and spring-loaded away from its normal operating position, swung into position. This moved a pinion gear to engage the flywheel ring gear, and simultaneously closed a pair of heavy-duty contacts supplying current to the starter motor winding. The starter motor cranked the engine until it started. An overrunning clutch in the pinion gear uncoupled the gear from the ring gear. The operator released the key-operated starting switch, cutting power to the starter motor assembly. A spring retracted the pole shoe, and with it, the pinion gear.

In this manner, unwanted starter disengagement is avoided before a successful engine start. The modern starter motor is a series-wound direct current electric motor with a solenoid switch (similar to a relay) mounted on it. When low-current power from the starting battery is applied to the solenoid (the thin, grey wire in the image above), usually through a key-operated switch, it pushes out a small pinion gear on the starter motors shaft and meshes it with the ring gear on the flywheel of the engine. The solenoid also closes high-current contacts (powered through the thick red cable in the image) for the starter motor and it starts to run. Once the engine starts, the key-operated switch is opened, a spring in the solenoid assembly pulls the pinion gear away from the ring gear, and the starter motor stops. Modern starter motors have a bendix   a gear and integral freewheel, or overrunning clutch, that enables the flywheel to automatically disengage the pinion gear from the flywheel when the engine starts. Chrysler and Ford both contributed to the starter market, with two types that were very different to those used on vehicles today. Chrysler manufactured a gear reduction starter employing a small gear to drive a larger gear attached to the starters pinion gear shaft. This allowed lower current to be drawn from the battery to run the starter, and still had the initial torque needed to turn the flywheel approximately at 200 rpm. This starter is also smaller and integrates the starter solenoid in the starter case, instead of having it mounted externally. Since this design weighs less, it has also been adapted to some light aircraft engines, where minimizing weight is very important. Fords version was slightly more complicated. The engineers at Ford Motor Company used a positive engagement style starter. This type of starter eliminated the solenoid, replacing it with a moveable armature and a separate starter relay. An armature is a part made of ferromagnetic metal that is magnetized by a coil of copper ribbon wound around it, creating an electromagnet. The Ford starter operated as follows: The operator closed the key-operated starting switch. A small electric current flowed through the starter relay coil, closing the contacts and sending a large current to the starter motor assembly. The armature moved a pinion gear to engage the flywheel ring gear, and simultaneously closed a pair of heavy-duty contacts supplying current to the starter motor winding. The starter motor cranked the engine until it started. An overrunning clutch in the pinion gear uncoupled the gear from the ring gear. The operator released the key-operated starting switch, cutting power to the starter motor assembly. A spring retracted the armature, and with it, the pinion gear. Current Ford starter designs incorporate the starter solenoid into the starter motor assembly, instead of mounting it on the firewall or on a fender. Starter motor A starter is an electric motor needed to turn over the engine to start it. A starter consists of the very powerful DC electric motor and starter solenoid that is attached to the motor (see the picture). A starter motor requires very high current to crank the engine, thats why its connected to the battery with large cables (see lower diagram). The negative (ground) cable connects -battery terminal to the engine block close to the starter. The positive cable connects +battery terminal to the starter solenoid. The starter solenoid works as an electric switch when actuated, it closes the circuit and connects the starter motor to the battery. At the same time, it pushes the starter gear forward to mesh with the engines flywheel. How the starting system works: When you turn the ignition key to the Startposition, the battery voltage goes through the starter control circuit and activates the starter solenoid, which in turn energizes the starter motor. The starter motor cranks the engine. A starter can only be operated when the automatic transmission shifter is in Parkor Neutralposition or if the car has a manual transmission, when the clutch pedal is depressed. To accomplish this, there is a Neutral safety switchinstalled at the automatic transmission, (or at the clutch pedal). When the automatic transmission is not in Parkor Neutral(or when the clutch pedal is not depressed), the neutral safety switch is open and the starter relay disconnects the starter control circuit. Simplified diagram of typical starting system Pneumatic Starter A Pneaumatic motor is a machine which converts in the form of compressed air into mechanical work. It converts it either in linear or rotary motion. Linear motion can come from piston actuator,while rotary motion is supplied by a piston air motor. These motors are very successful in hand-held tool industry. Classification Linear In order to achieve linear motion from compressed air, a system of pistons is most commonly used.   The compressed air is pumped into an air tight chamber that houses the shaft of the piston.   Also inside this chamber a spring is coiled around the shaft of the piston in order to hold the chamber completely open when air is not being pumped into the chamber.   As air is pumped into the chamber the force on the piston shaft begins to overcome the force being exerted on the spring. As more air is pumped into the chamber, the pressure increases and the piston begins to move down the chamber. When it reaches its maximum length the air pressure is released from the chamber and the spring completes the cycle by closing off the chamber to return to its original position.   Piston motors are the most commonly used in hydraulic systems. Essentially, piston motors are the same as hydraulic pumps except they are used to convert hydraulic energy into mechanical energy.    Piston motors are often used in series of two, three, four, five, or six cylinders that are enclosed in a housing.   This allows for more power to be delivered by the pistons because several motors are in sync with each other at certain times of their cycle Rotary Another type of pneumatic motor, known as a rotary vane motor, uses air to produce rotational motion to a shaft.   The rotating element is a slotted rotor which is mounted on a drive shaft. Each slot of the rotor is fitted with a freely sliding rectangular vane.[3] The vanes are extended to the housing walls using springs, cam action, or air pressure, depending on the motor design. Air is pumped through the motor input which pushes on the vanes creating the rotational motion of the central shaft. Rotation speeds can vary between 100 and 25,000 rpm depending on several factors which including the amount of air pressure at the motor inlet and the diameter of the housing.[1] Rotary motion vane type air motors are used to start large industrial diesel or natural gas engines.   Stored energy in the form of compressed air, nitrogen or natural gas enters the sealed motor chamber and exerts pressure against the vanes of a rotor.   Much like a windmill, this causes the rotor to turn at high speed.   Because the engine flywheel requires a great deal of torque to start the engine, reduction gears are used. Reduction gears to create high torque levels with the lower amounts of energy input. These reduction gears allow for sufficient torque to be generated by the engine flywheel while it is engaged by the pinion gear of the air motor or air starter. Application A widespread application of small pneumatic motors is in hand-held tools, power ratchet wrenches, drills, sanders, grinders, cutters, and so on. Though overall energy efficiency of pneumatics tools is low and they require access to a compressed-air source, there are several advantages over electric tools. They offer greater power density (a smaller pneumatic motor can provide the same amount of power as a larger electric motor), do not require an axillary speed controller (adding to its compactness), generate less heat, and can be used in more volatile atmospheres as they do not require electric power.Some gas turbine engines and Diesel engines, particularly on trucks, use a pneumatic self-starter. The system consists of a geared turbine, an air compressor and a pressure tank. Compressed air released from the tank is used to spin the turbine, and through a set of reduction gears, engages the ring gear on the flywheel, much like an electric starter. The engine, once running, powers th e compressor to recharge the tank. On larger diesel generators found in large shore installations and especially on ships, a pneumatic starting gear is used. The air motor is normally powered by compressed air at pressures of 10-30 bar. The air motor is made up of a center drum about the size of a soup can with four or more slots cut into it to allow for the vanes to be placed radially on the drum to form chambers around the drum. The drum is offset inside a round casing so that the inlet air for starting is admitted at the area where the drum and vanes form a small chamber compared to the others. The compressed air can only expand by rotating the drum which allows the small chamber to become larger and puts another one of the cambers in the air inlet. The air motor spins much too fast to be used directly on the flywheel of the engine, instead a large gearing reduction such as a planetary gear is used to lower the output speed. A Bendix gear is used to engage the flywheel. Some smaller diesel engines such as ones found on tugboats and lifeboats use hydraulic start motors in which the air motor is replaced with a hydraulic motor. While running, the engine shouldnt be shut down unless the hydraulic accumulators for the starting motor are recharged. Otherwise there is a manual hand pump to slowly pump up the accumulators. Since large trucks typically use air brakes, the system does double duty, supplying compressed air to the brake system. Pneumatic starters have the advantages of delivering high torque, mechanical simplicity and reliability. They eliminate the need for oversized, heavy storage batteries in prime mover electrical systems. BIBLOGRAPHY WWW.GOOGLE.COM WWW.WIKIPEDIA.COM WWW.PHYSICS.ORG

Reason and Religion in Fulgens and Lucres Essay -- Fulgens Lucres

Reason and Religion in Fulgens and Lucres      Ã‚  Ã‚  Ã‚   Seeing that the main purpose of college is to educate, perhaps the college administration might take a lesson from the 16th Century citizenry of England and host a fantastic dinner play in the fashion of Medwall's famous, Fulgens and Lucres.   This interlude, small in cast members but big on Humanism, demanded that each viewer take an active role in the performance; the play, though covering many morals and ideologies, focused on the everyday interaction between the two seemingly opposite poles of religion and reason.   Though poising as mere dinner entertainment, Fulgens and Lucres served the goal of enlightening its audience toward the apex of the English Renaissance - the need to unite reason and religion within the life of each and every person.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Before one can ponder over the relationship between reason and religion, a person must first receive the proper education.   As Sir Thomas Wyatt, Erasmus, and Sir Thomas More, the last being possibly an actor in this very play during his youth, claim throughout their works and letters, the key aspect to being a decent, contributing member of society rests in the pages of books, dwells within the classroom, and glitters on the lens of a telescope; knowledge undeniably holds the key to developing a logical, autonomous human being.   In his Book of the Governour, Wyatt developed his own theory as to the proper raising of a young boy so he could someday attain to reach a position in the royal court.   Although, he ludicrously clamored for the importance of a nurse's milk to the young infant and complete isolation from women during a boy's studies, Wyatt declares, "a tutor should be provided," (Wyatt 43) to the bo... ... Medwall raises the antey up a notch though, and proclaims that reason without religion will serve no justice.   Reason, when kept in check by religious beliefs, will, just like Lucres and Gayus, make for the perfect marriage and will guide the educated person down the path of enlightenment and true knowledge.    Works Cited and Consulted Baskerville, Charles R. 1927.
