Scientific principles and techniques - Essay Example Mechanics are based on a few laws of nature which are evident without proof or argument. Mechanics is a highly developed branch of physics which is tasked with the determination and description of the motion of bodies and the investigation of the forces that are associated with the motion (Gross, et al. 2009). Suspension system The suspension system of a car is a collection of important systems that are located on the lower part of the car and are part of the chassis. These include the frame, suspension system, steering system and tires and wheels. The suspension of a car is mainly composed of three systems namely springs, dampers and anti-sway bars. Springs are based on four designs: coil springs which are the most common and are made of a heavy-duty bar that is coiled around an axis. They compress and expand when a force is applied on them to absorb the motion of the wheels; leaf springs which are made up of several layers of metal that are bound together to perform as a single uni t. They absorb shock in trucks and heavy-duty automobiles to reduce the force exerted on the wheels; torsion bars which are made of a steel bar that is coiled; and air springs which are made up of a cylindrical chamber of air placed between the wheel and the body of the car. Manufacture The material is commonly used is alloys of steel such as high-carbon, chrome vanadium and stainless steel. The manufacture process of the springs involves coiling, hardening and a final stage of finishing. Leaf springs are made from bars of flat stock and are heated to elevated temperatures. They are then formed by the use of a machine or by hand. Car springs are made by hot winding which involves heating the metal to very high temperatures to make it formable. When red hot, the bar is then coiled around a mandrel until it acquires the required shape then it is quickly removed from the mandrel and dipped in oil to cool and harden it. To ensure the spring acquires the required strength it is heat trea ted appropriately. For the leaf springs, the flat ends are attained by grinding. The bar is mounted in a jig and is held against an abrasive wheel that is rotating until the required flatness is achieved. A coarse wheel is used first then a finer wheel is used to ensure a fine finish and a cooling lubricant is used to ensure a quality finish and to increase tool life. In a subsequent processes, the spring is exposed to bombardment with tiny steel balls that hammer the steel and make it smooth and this ensures that the steel can resist fatigue and cracking after years of use. The spring is then compressed fully in order to achieve the desired pitch and length and this process is sometimes repeated severally. The coating process which is aimed at preventing corrosion of the metal is the next step. The entire surface of the metal is either painted, dipped in liquid rubber or plated with another metal for example chromium or zinc though electroplating. The spring is then tested through various quality control checks to ensure it adheres to the standards. Function They support the weight, absorb and reduce shock and help to maintain contact by the tire on the road surface. 1. Statics. At rest the coil spring is extended with the only force acting on it being the weight of the car. The leaf spring is curved at rest or when no force is acting on it. 2. Strength of materials. The springs in a car are made of a strong heavy-duty bar that is made of steel. This

The United States of America Essay The year is 2039 in the United States of America. There is a new mandatory government law and procedure that requires all American citizens to adhere to. The procedure is called the Ein which is a German word that means â€Å"one†. The procedure changes all normal human beings as we know them into super intelligent people and reconstructs them into beautiful beings. The process starts on an automatic escalator on which the human being rides, and travels from one machine to the next. The first machine controls the brain by using an automatic electronic head piece that descends from above onto the human head. The electronic headpiece shocks the brain and reprograms everything that is sympathetic such as emotions, empathy and creativity. After that part of the brain is completely numbed, the computer programming begins to transform the mind, turning everyone who enters into alienated, egocentric human beings. After the process is done, the human is totally dumbfounded and automatically moves to the next machine which is called the Van-Trans. To keep the human from feeling any pain, he or she is first injected with a super pain reliever and then the human’s skeleton reshapes into a human box. After the person is shaped like a box, the Van-Trans start the reshaping procedure. After molding and trimming, the person is created into a supermodel form. This is a governmental standard requirement for all people to follow who resides within the United States. All of the humans who are recreated are referred to as Supers by the government. Finally, when the procedure is finished, the Super is now allowed to exit the Machine. On one occasion after having the procedure done, there was a young woman who witnesses a little girl who was hurt in a car accident and she needed the young woman’s help. The little girl was unconscious and no one would help her because of how the required procedure affects everyone who has the procedure done. All of their emotions and compassion is removed during the procedure. Therefore, the woman just stepped right over the child having no feeling at all for the little girl. The world has been turned into a heartless society. The government has created a society that is numb to having feelings and worships their intellect and outer man. â€Å"Power has become so subtle and complex a thing [†¦] that only a subtle mind can watch it work; here it is still limited, still visible† (LeGuin 5). The people’s only power is their knowledge but they use their knowledge to get over on others who are not Supers like them. â€Å"Nothing succeeds like success† (LeGuin 5).

The Republic Essay -- essays research papers

Most normal individuals in the modern world would assume that all books written, not published, by man are based on either a portion of the author’s imagination, an event (biased or non-biased) in either history or during the life of the author, a straight-out autobiography, or a generalized biography of another person they once knew. However, this philosophical novel fits none of the descriptions above. The book is actually an in-depth recording of a philosophy contest between Plato’s teacher Socrates and several other great philosophers. What is significant about this contest is that, in it, Socrates describes his personal view of a â€Å"perfect world,† and why justice is so important in the process of creating a civilized world.The novel was completed in 370 B.C., and it describes a strong debate between Socrates and five other speakers. The two main arguments that he illustrates in this novel are that a ruler cannot obtain more power than the state, and that a philosopher is best suited to rule a nation since he has the ability to maintain this balance. Also, Socrates claims that only the philosopher has traveled beyond the â€Å"cave† of worldly desires and temptations to discover what justice really is. Socrates’ first major argument is with Thrasymachus in Book I. The current debate lies on the pure definition of justice. Thrasymachus claims that there is only one principle of justice: the interest of the more dominant force. Socrates counters this argument by using the phrase â€Å"the stronger.† He claims that the ruler of a nation will not be aided, but harmed, by an unintentional command, in the long run. Socrates then builds his argument gradually by stating that the good and just man looks out for the interest of the weaker, and not for himself. Thrasymachus tries to counter Socrates’s argument by vaguely proclaiming that injustice is more gainful than justice.However, Socrates bravely explains that the just man will live happily because he has a just soul, and the man with the unjust soul lives in poverty; therefore, injustice can never be greater than justice. At this point in the novel I saw Thrasymachus’s flaw and also the reason why Socrates has silenced Thrasymachus. Injustice, in my opinion, may be better as a short-term plan for pleasure, but in the long run the unjust man will be condemned by just men of his evil deeds, thus leading to his downf... ...nally, Socrates points out that, in his perfect State, philosophers will always have the advantage over other types of rulers because they have wisdom and knowledge, which gives them the ability to govern justly and wisely. In my opinion, Socrates’s perfect State sounded plenty like the scenario progressing in the debate. Socrates, since he is a great philosopher, had the advantage over everyone because he was wise and intelligent in his arguments; therefore he obviously knew more about justice than anyone else. So, in conclusion, Socrates won the debate on the definition of justice. The reason for this is because Socrates, as stated before, had the wisdom and knowledge to analyze, in the most descriptive way, what justice really is. Glaucon and the others lacked what Socrates had, and so they could not support their arguments as well as Socrates could. I really liked this novel a lot because I am a lover of philosophy and understanding. However, I must admit that some of Socrates’s arguments were redundant and besides the point. But other than this crucial flaw, the book showed great insight, and Socrates created a vivid description about what justice means to the modern world.

Freedom is being accepted

Freedom is defined as â€Å"the state of being free or at liberty rather than in confinement or under physical restraint† (Dictonary. com). When you arrive to a new town you are somewhat free, although unless you are accepted by the town, you won’t feel free. In his short story, The Strangers that Came to Town, Ambrose Flack shows that true freedom is about being accepted. This is shown by the people in town mocking the Duvitches for who they are, and also by Tom and Andy poisoning the Duvitches fish they caught. The Duvitches don’t feel accepted until the dinner at the Duvitches that changes their perspective on how they are. Firstly, the town mocks the Duvitches about everything. â€Å"Before she could put a stop to it, some of their classmates scoffed at the leaf, lard and black bread sandwiches they ate for lunch, huddled in one corner of the recreation room, dressed in their boiled-out ragpickers’ clothes†(Flack 4). In this statement the Duvitch kids don’t feel freedom at school because they are not accepted due to what they eat and how they are dressed. Even the school principal is not very accepting to the Duvitch kids. â€Å"Mrs. Lovejoy, the principal, said they were bright, conscientious, pathetically eager but almost pathologically shy† (Flack 4). Everyone in town did not accept the Duvitches, this is well stated when Flack says â€Å"To the young Duvitches, like their parents, were considered antisocial† (Flack 4). The Duvitches get mocked by everyone so it is hard for them to be free because nobody in town accepts them. Secondly, when Tom and Andy poison the Duvitches fish, the Duvitches felt like they are not accepted and have no freedom. Not only had Tom and I snatched precious food from their mouths but we had brazenly advertised the contempt in which we held them† (Flack 7). Tom and Andy take away the Duvitches meals for almost a whole week that they are not able to afford, that is a way of showing them that they are not accepted. â€Å"But there was no hostility, no animosity towards us in the man an d it was obvious that he considered himself too humble to receive an apology, finding it, like most of life’s troubles, a mockery to be endured without protest† (Flack 7). This statement shows that the Duvitches never received apologies; they are shocked because they are never accepted anywhere or free from getting mocked. The Duvitches do not deserve to be treated this way and it did not help them get a good taste of freedom because they are not accepted. Thirdly, after the boys recollect all the fish they killed and gave them back to the Duvitches; it makes them, the Duvitches, feel as if they are starting to get accepted in town. Overjoyed to have neighbors in his house, he was so full of himself that I was conscious of an invisible stature in him which made him seem quite as tall as Father† (Flack 14). This is proof that Mr. Duvitch is starting to feel accepted and free in the town because he is constantly smiling and proud of himself. Also the statement when Flack says â€Å"How strange to see the boys and girls throw back their heads and laugh when Father said something that was funny, but not terribly funny. † (Flack 14) This shows that the Duvitches feel freedom; they have freedom to laugh and have fun without having to worry about being accepted. Feeling accepted gives you a reason to smile and have fun and that was produced when they got accepted. In conclusion, true freedom is about being accepted. It’s proven in the story The Strangers that Came to Town when their family is getting mocked by everyone in town, Tom and Andy poisoning the Duvitches fish and when they had dinner at the Duvitches. Freedom comes from feeling accepted by your surroundings, if you aren’t accepted by them how do you expect to be happy and feel free from negativity?

The First Amendment Of The United States Essay - 970 Words

The first amendment of the United States Constitution protects the right to freedom of speech and expression. One particular form of expression that has grown in popularity is body art; also known as tattoos. This creative form of expression can be displayed anywhere on the body. It is because of this same freedom that I believe there should be restrictions on what and where a tattoo is placed. Some feel as if the Marine Corps shouldn’t have any tattoo restrictions. But I strongly disagree. This Organization has been built on so many great principles, like our Corps Values: â€Å"Honor, Courage, and Commitment.† Then we have our official United States Marine Corps (USMC) slogan: â€Å"The Few, The Proud, The Marines†. We have a reputation for being a professional, disciplined fighting force. Granted, society will always change. From the modern day fads, the fashion statements, to the personal beliefs plus the need to be an individual; we as a people can change i n the blink of an eye. But should we allow that to dictate the USMC? Should we change our foundation because of our society? Although tattoos have become a part of the societal norm, in order to maintain good order, discipline, and a professional military appearance; restrictions must remain in place. The first reason I believe there should be tattoo restrictions in the military is because society’s perception of their military is very important.

The Leadership Style Of The 21st Century - 1435 Words

It is apparent in the history of management that it is common for supervisors to embrace the most current fad under the guise that they are going to be ahead of the competition. New books are always hitting the market touting new theories and new styles of management that are proven to be successful. Even out of the three most common leadership styles, authoritarian, democratic and laissez-faire, the latter, is still considered a fad and too risky. Laissez-faire (french for leave us alone ) is a style where the workers have the decision making power. Even as recent as 2008 Samual C. Certo wrote â€Å"Supervisors are rarely, if ever, able to practice this style of leadership because the nature of the supervisor s job requires close†¦show more content†¦Government was only looked to when legal matters needed attention, such as safety, protection or contracts. This acceptance of the leadership style went by the wayside when the industrial revolution arrived and the techniqu e of mass production began. In the 20th century laissez-faire has was not recommended since its disadvantages always seemed to outweigh the advantages. Advantages include: leaders allow team members freedom to make decisions team members are motivated and gain more experience Disadvantages include: team members missing deadlines team members lacking personal growth team members producing low quality work So lets look at some current companies and why they are successful with laissez-faire. As early as the 1970 s we see that society is starting to lean towards this leadership once more. Steve Jobs, founder of Apple Computers, implemented the laissez-faire style and it proved to be very innovative. Because of the work environment it encouraged the creativity of the employees and became the forefront of new technologies (Tkd 12).
