The safety features in modern cars

The safety features in modern cars There are many different types of safety feature in cars. The different safety features all have their own thing that they do. There are nine very important safety features that are needed in cars. They are seatbelts, airbags, head injury protection, head restraints, antilock brake system, traction control, all wheel drive, electronic stability control and weight. The two safety features that will be discussed in this report will be airbags and traction control. These two safety features will be found in most or even all modern cars. Airbags is a restraint that is used to prevent the driver, of the car, does not hit the dashboard and the steering wheel, which could cause serious injuries to the neck and head. Airbags will help the driver if he/she is wearing a seatbelt. â€Å"To date statistics,† in America, â€Å"show that airbags reduce the risk of dying in a direct frontal car crash by about 30 percent.† This quote is taken from How stuff Work? How airbags work? The law of motion that is used for airbags is Momentum, unless there is an outside force acting on the object. One of the main goals of airbags is to slow down the driver and its passengers motion as slowly and as evenly as possible. There are three main parts to airbags, they are; the bag, the sensor and the inflation system. In this report I will be discussing the three parts briefly. The bag is made up of a thin piece of nylon fabric, which is folded into the steering wheel, or dashboard, or the seat, or the door. The sensor is a device that allows the bags to know when it has to inflate when there is a force on the car that has a speed of 16km/h to 24km/h. There is a mechanical switch that will be flipped if there is a sudden change in mass in the vehicle. The inflation system combines to chemicals, sodium azide and potassium nitrate, to produce nitrogen gas. The hot blast of nitrogen inflates the bag. There are many safety concerns of airbags. Airbags have to work together with seat-belts because the force at which the airbags are expelled is enough to cause serious injury if the driver and the passengers arent wearing their seatbelt. The risk zone of airbags is the first 5 to 8 cm of inflation. Airbags have been known to seriously injure or even kill children that are sitting to close to it or even thrown towards the dashboard in an emergency braking. Children should sit in the back to, so that they are protected from the force of the airbags. There are some cases, in America in particular, where drivers have deactivate there airbags in certain cases because of the amount of injuries by the over-powerful force of the airbags. The driver of the car would have to get authorisation by the National Highway Traffic Safety Administration, in America, to get an on/off switch for on or both of their airbags; authorisation was only giving if you fell into one of the four categories. These categories are: ÂÅ ¸If the driver and the passenger both have a medical condition, where the risk of the inflation of the airbags exceeds the risk without an airbag. If the driver is unable to position him-/her- self the correct distance away from the dashboard and the airbag. ÂÅ ¸ There is no rear or there is not enough room in the back of the car to put a rear-facing car seat or the driver has to monitor the childs medical condition. ÂÅ ¸ If the driver has to carry children because there is no space in the back or there is no rear seats. The deactivation of airbags will not be authorised if you have certain other problems. These problems are pacemaker, eyeglasses, angina, emphysema, asthma, mastectomy, previous back or neck injury, advanced age, osteoporosis, arthritis, and/ or pregnancy. The Newtons Law that is used for airbags is Newtons first Law. Newtons first Law states that a body will continue in its state of rest or uniform velocity unless acted on by an external resultant force. This is also known as the Law of Inertia. Inertia is that of a body which must overcome in order to produce an acceleration or deceleration. The passenger of the vehicle goes forward very rapidly because it has a uniform velocity but the body is either being held back by the seatbelt and also stopped by the airbag, so this is the resultant force, body is stopped before hitting the dashboard. Traction control system helps to improve the stability of the vehicle by controlling the amount the drive wheels can slip when you apply excess power. The output of the engine power is adjusted automatically by the system. The system, in some cases, will adjust the applied braking force on selected wheels during acceleration. Traction control is a secondary function of the anti-lock braking system. This system is becoming more common in most modern cars. Traction is the friction that the car uses to stop, get going and to stay on the road. This system is like ABS but it is in reverse. ABS prevents your wheels from freezing when you are stopping which could cause you from skidding and having an accident. Traction control does a similar thing, but instead it stops the wheels from freezing or locking up when you accelerate. The basic set-up of traction control system is that there is a mechanical linkage between the throttle and the accelerator pedal. Occasionally the mechanical linkage is replaced by an electronic drive-by-wire system. The electronic drive-by-wire system means that instead of having a direct link from the pedal, to the throttle. Instead it sends signals from an electrical connection to a sensor. The sensor then translates the information that the electronic connections give off, by the amount of pressure you put on the accelerator. Then the sensor passes on the information into a control unit and then it sees it the wheels are slipping or not. There are benefits to having traction control system installed in the car. The traction control works so effortlessly that you may never know that it is on. The benefits are that it lowers the risks of skidding and having a major accident when the vehicle is going around the corner when the road is wet. This system is very evident when you accelerate from a complete stop. If you didnt have this system, especially if you had a very powerful car, the vehicle and the tires will go in the direction in which they were not intended to go because of skidding. The system helps with regulating the amount of power that will be sent to tire, to prevent the skidding. Theses two safety features are very useful in the vehicle but both need the driver plus the passengers to wear there seatbelt. If the passengers and the driver dont wear their seatbelts they will still get seriously injured which could lead to death. The car need to be evaluated to see if the safety features are correctly put in and safe to use.

SAD in the Winter Essay -- Journalism Journalistic Essays

SAD in the Winter Could Seasonal Affective Disorder Be Disrupting the Lives of Northeastern Students? Becky Venne, a 31-year-old Northeastern graduate student, says she doesn’t socialize much in the winter. In fact, she claims that she finds it hard to get out of bed and spends most of her day watching T.V., satisfying her cravings for carbohydrates and starchy foods. We’ve all experienced it at some point or another. The weather gets colder, the days become shorter, and no matter how much sleep you had the night before, you still feel tired. These, along with weight gain and feelings of sadness and lethargy are common during the winter months. But what happens when these feelings become debilitating, and begin affecting one’s personal life? â€Å"There is a period of time that I think most people who have SAD realize there is more to it,† said Venne. â€Å"It wasn’t until I had some quiet time that I realized this isn’t normal.† What Venne is referring to is Seasonal Affective Disorder (SAD), a mood disorder that more commonly affects people of all ages in the Northern regions of the Unites States. Although most people experience some forms of depression during the winter months, SAD is diagnosed when this change in mood becomes debilitating, causing a sever impact on the daily life of the individual. Venne says she was diagnosed with SAD about five years ago, shortly after she moved to Boston. She describes her diagnoses as a long, drawn out process, jumping from doctor to doctor, until finally she found the right psychopharmacologist. Dr. Elisa Castillo works at the Center For Counseling at Northeastern University, where she works with many students who have been diagnosed with SAD. She explained that there are... ...the answer to SAD? Castillo suggests seeking help through Counseling, such as the Center for Counseling and Student Development. â€Å"The counseling center can provide support, help diagnose SAD, help with referrals to psychiatrists that have experience in this area and follow up with students to make sure the treatment is working,† said Castillo. Castillo also says that it is important to learn how to manage winter, and can be difficult, especially if someone has moved from a warmer climate to Boston. She recommends finding ways to exercise, socialize, and learn how to have fun both indoors and out. Venne agrees that it is important to find help if a person is experiencing symptoms of SAD. â€Å"Once I was able to realize what the problem was, I was able gain some sort of control,† said Venne. â€Å"I just take one day at a time, and know that summer is on its way.†

Classroom Shortage Essay

Introduction This is an often problem of most high schools. The numbers of students become bigger while the numbers of classrooms are still the same. Due to this situation, some students at the back are having some difficulties, they cannot concentrate to the discussion on that the teacher had prepared because they barely hear the lessons. The teachers also are having a tough time in balance provision of all students so that some of the students could not relate to the topic. Most of the times, especially during afternoon, students are suffering from a hot weather because our school also needs to enhance proper ventilations. Due to this problem, students can’t focus in the lesson because sometimes they feel irritated. They are not able to learn in a congested classroom. Some of the students and teachers are pushed to study in the covered court or sometimes in the stage, because of this, they cannot concentrate to the discussion because they are distracted by the students who passed by and who makes noises. And it is also the cause why students do not attend their class and just spent their time in the canteen. As we all know because of the classroom shortage, our schedule is not well fixed. Pointing on this situation is a problem we need to take action. They lose the chance of the students to study comfortably without distractions and hindrances. We may get the high quality of education if they will provide more classrooms to accommodate new students coming from other schools.

The Anti War Movement Of The Vietnam War Essays - Free Essays

The Anti War Movement Of The Vietnam War Essays - Free Essays The Anti War Movement Of The Vietnam War The Anti-War Movement J,J,J,J, United States participation in the Vietnam War was a subject of much debate among the American public. While many Americans supported the United States involvement in the War, in agreement with the Government that American assistance was needed in order to stop the spread of Communism, other people felt that it was immoral for the United States to involve itself in another country's internal matters. The antiwar movement against Vietnam in the US from 1965-1971 was the most significant movement of its kind in the nation's history. Anti-war protesters were not confined to the young, radicals, intellectuals, and the disaffected. By 1968, [they] included many powerful individuals within the business and financial communities, the media, and the government itself ( McMahon 466). Also by 68, protesters numbered almost seven million, with more than half being white youths in the college. Students for a Democratic Society, (SDS), announced its opposition of the Vietnam War publicly in 1965. In a public announcement, they state their reasons for disagreement. We feel that the war is immoral at its root, that it is fought alongside a regime with no claim to represent its people, and that it is foreclosing the hope of making America a decent and truly democratic society.We are anxious to help and to change our country; we refuse to destroy someone elses country (McMahon 467). The SDS was not alone in their opposition. Civil-Rights leader, Martin Luther King, Jr., declared his opposition in 1967. He stated many reasons. it became clear to me that the war was doing far more than devastating the hopes of the poor at home. It was sending their sons and brothers and their husbands to fight and dieAs I walked among the desperate, rejected and angry young men, I have told them that Molotov cocktails and rifles would not solve their problemsBut, they asked, what about VietnamTheir questions hit home, and I knew that I could never again raise my voice against the violence of the oppressed in the ghettos without having first spoken clearly to the greatest purveyor of violence in the world today my own government (McMahon 471). One aspect of the anti-war movement were teach-ins. Teach-ins were mass public demonstrations, usually held in the spring and fall seasons. These well-publicized rallies made the antiwar effort more respectable. The White House was plagued by two wars: the war in Vietnam and the war at home. In October 1967, protesters marched on the Pentagon. This was one of the most significant events of the antiwar movement. Although the marchers were unable to get into the Pentagon, this demonstration had a direct influence on the redirection of American policy in Vietnam. The antiwar effort crippled Johnson's presidency. In 1968 he announced that he would not be running for re-election. The antiwar movement inadvertently helped Richard Nixon win the election. Once elected, Nixon was bothered with the antiwar movement. He was convinced that it prolonged the war. He could not understand how the current generation of young people could include brave young marines, hippies and draft-card burners. In May 1970, Nixon ordered an attack on Cambodian sanctuaries to destroy communist command-and-supply buildings. He also tried to contain the protest that he knew his action would provoke. His hopes of controlling the rally failed when poorly trained National Guardsmen killed four students at Kent State University, on May 4. This made the expected protests much worse than anyone in Washington could have foreseen. The wave of demonstrations on hundreds of college campuses paralyzed America's higher-education system. The Kent State tragedy ignited a nationwide campus disaster. Between May 4 and May 8, campuses experienced an average of 100 demonstrations a day, 350 campus strikes, 536 colleges shut down, and 73 colleges reported significant violence in their protests. On that weekend, 100,000 people gathered to protest in Washington. By May 12, over 150 colleges were on strike (Internet source). The overwhelming response to the invasion of Cambodia and the Kent State crisis soon became too much for President Nixon. On December 15, Nixon announced his intention to withdraw fifty thousand troops from Vietnam in 1970 Among the most convincing theories of the movement were that it

Elizabeth Lavenza in Frankenstein Essays

Elizabeth Lavenza in Frankenstein Essays Elizabeth Lavenza in Frankenstein Paper Elizabeth Lavenza in Frankenstein Paper In her Introduction to the 1831 edition of Frankenstein, Mary Shelly characterized her revisions as principally those of style and added that she had not introduced any new ideas and circumstances or altered the storys core and substance. After reading the original (1818) and the revised (1831) version of Frankenstein, I believe the changes that Shelly has made to the 1831 edition are far more than Just a variation in style or cosmetic. She does make a few changes to the characters profiles and their relationship in the 1831 edition. In this essay, I am going to use the most ignificant woman character in this novel, Elizabeth Lavenza, Victor Frankensteins fianc? ©e, to present my finding. In the original and the revised versions, the story begins with the letters of Captain Robert Walton to his sister and the narration of Victor Frankenstein to Walton. Victor starts with his family background and early childhood, telling Walton about his father, Alphonse, and his mother, Caroline, and how they get married. He then goes on describing how his childhood companion, Elizabeth Lavenza, entered his family. It is at this point in the narrative that the 1818 and revised versions of Frankenstein diverge. I must record an incident which took place when I was four years of age. My father had a sister, whom he tenderly loved, About the time I mentioned she died; and a few months afterwards he received a letter from her husband, acquainting him with his intention of marrying an Italian lady, and requesting my father to take charge of the infant Elizabeth, the only child of his deceased sister My father did not hesitate, and immediately went to Italy, that he might accompany the little Elizabeth to her future home From this time Elizabeth Lavenza became my playfellow, and, as we grew older, my friend. (1818 original version) In the original version, Elizabeth is Victors cousin, the daughter of Alphonses sister. When Victor is four years old, Elizabeths mother dies and she is adopted into the Frankenstein family. Caroline plays no role at all in making the decision to bring Elizabeth into Victors life. When I was about five years old my father had gone by himself to Milan, my mother, accompanied by me, visited this abode. She found a peasant and his wife, hard working, bent down by care and labour, distributing a scanty meal to five hungry babes. Among these there was one which attracted my mother far above all the rest The peasant woman, perceiving that my mother fixed eyes of wonder and admiration on this lovely girl, eagerly communicated her history the result was that Elizabeth Lavenza became the inmate of my parents housemy more than sister the beautiful and adored companion of all my occupations and my pleasures. 1831 edition) In the 1831 edition, it is Victors mother, Caroline, who finds Elizabeth and sets about Elizabeths arrival, Victors mother says, l have a pretty present for my Victor- tomorrow he shall have it. (1831 edition) Caroline decides at the moment of the doption that Elizabeth and Victor should marry someday. I think the change of Elizabeths past brings to the 1831 edition presents a better marriage equality picture between Victors father and mother. When Victors father returns from his trip to Milan, Elizabeth is playing with Victor at home. Caroline explains what has happened and her own desire to make Elizabeth a member of the family is shared by her husband. Her interest in helping the less fortunate has made her fulfilled her role as a mother of a daughter as well as a son. This change adds a view that is missing from the 1818 version in which Elizabeth comes to the Frankenstein home as the result of a decision made by two men, Victors uncle and his father. In addition, the love relationship between Victor and Elizabeth in the 1818 original version is clearly incestuous because they share the same bloodline. In the 1831 edition, Elizabeth is an adopted child that eventually receives the name of cousin. As a result, the later version has removed any suggestion of an incestuous relationship because Elizabeth is converted into an unrelated person of Victor. With the above evidence in mind, I cannot agree with Shelly that her changes in he 1831 edition are merely related to lexical concerns. However, I must say the main plot is not much of a difference between the 1818 and the 1831 editions. Be it a three volumes in the 1818 original version or a single full volume in the 1831 edition, the story is still about a crazy scientist who is fascinated with the secret of life, discovers it, and brings a hideous monster to life. While I agree that the influence of Elizabeth is an important element of the novel to notice, I dont think this character is given significant importance in a direct role and therefore, altering my experience of the novel as a whole.

Personal Statement Example Due to my keen interest in the world of supplies, demands, distribution, revenue, profit and customer satisfaction, the field I would like to choose for my major is economics. After sensitive calculations and critical working, I took initiative to start off with my own â€Å"mini business†. I perceived it as a business that would not only be beneficial for students but would also allow me to earn a good deal of experience in the practical world alongside the profit. By assigning target goals and dividing the entire process into the stages of ‘plan’, ‘purchase’, ‘sell’ and ‘generate revenue’, I was able to keep the business simple yet effective. The plan included listing the items that were in demand and researching the availability of whole-sale vendors who could provide the required products. These items were then sold at a reasonable profit, which was later utilized for further betterment of the business. In the ‘reve nue generation’ stage of my business venture, I calculated the amount of time, energy and fuel consumption while commuting to the wholesale market and finally completing the purchase. With this data, I calculated a reasonable profit that was to be earned from the business. ... uced a new well-equipped market within the campus, while I ended the business and decided to focus on the final months of studying for my high school.

Prompt 2 After discussions with my father that lasted for hours, I was forced to admit the fact that my twenty years of life have not really been much of a success. Before I had joined Community College, the grades that I had obtained were not up to the mark. Due to my father’s motivation and support, I had always wanted to set an example, not only for my dad but also for m y children in future. It cannot be ignored that I had gained exceptional business experience at a very young age but I realized that despite starting off as an entrepreneur and managing it well, there were many concepts I still had to grasp. I believe that the best possible way to be introduced to these concepts would be to undertake a university major in economics. At the beginning of my high-school years, I was introduced to a poem by Robert Frost, titled â€Å"And miles to go before I sleep†. This poem inspired a great sense of motivation within me and continually makes me believe that there is always a lot more that life has to offer. Since I was determined in what I believed, I took an oath to bring about a change. As I resumed my studies in the Community College, I worked hard day and night. My
