Anti Lock Braking System: How It Works?
As I said in the last article, Anti Lock Braking System - Use of Abs in Cars, that in case of emergency, applying and releasing brakes continuously will reduce the stopping distance by a considerable margin as well as prevent the wheels from locking so you can steer the vehicle away from the object, but, the fact is, whatever I said, sounds so easy to do but so tough to actually perform. Think honestly, how many of you actually remember performing this in such a panic condition? Actually, no one and apart from this, even if you remember to do so, how fast actually you can perform the act of pressing and releasing of brakes? Not much, at least less than the required speed of doing so.
Here comes ABS in picture. Whatever action of pressing and releasing the brakes is concerned, it does it with accuracy and required speed without failure. It presses and releases the brakes almost 20 times a second, stopping the vehicle in a shorter time and distance. But how? How it knows that it has to do this? How it knows that the wheel has locked up? What is that which applies and releases brakes continuously when actually it’s only you who pressed the brake pedal? I will tell it all.

Source: http://home.iitk.ac.in nti lock braking system is made up of a central (ECU) Electronic Control Unit and four wheel speed sensors connected to each wheel of vehicle and two hydraulic valves located in the brake hydraulics. The electronic control unit monitors the rotating speed of four wheels on a constant basis and when this system finds a vehicle wheel rotating speed slower than the other three, where a situation arises such as an impending wheel lock, here the ABS system causes the valves to constantly reduce hydraulic pressure to brakes of the significantly lowered speed wheel thereby causing reduction of braking force on the affected wheel.

A320 Landing Gear System

...INTRODUCTION An exactly analysis of the landing gear, as designed on modern aircraft’s, is necessary to understand the construction and systems of the landing gear of the Airbus A320. Operation of the landing gear is made possible through extension/retraction, steering, braking and damping systems. In order to maintain the safety of the aircraft, the design of the landing is satisfied to the legislation of the European Aviation Safety Agency . With the knowledge of the landing gear construction of the Airbus A320, the forces on the construction calculated during different flight phases. In these flight phases the aircraft endures several forces. The materials that are used depends on the forces at the aircraft . Then, with a good insight of the A320’s landing gear I’m able to provide an in detail overview of the common faults and problems of the A320’s landing gear. These faults and problems have consequences for the aircrafts airworthiness. Change in the aircraft’s airworthiness requires maintenance with inevitable costs for the airline . The used main sources, serve as information to learn how the landing gear of the Airbus A320 operates.

...states. The proposed Constitution, and the change it wrought in the nature of the American Union, spawned one of the greatest political debates of all time. In addition to the state ratifying conventions, the debates also took the form of a public conversation, mostly through newspaper editorials, with Anti-federalists on one side objecting to the Constitution, and Federalists on the other supporting it. Writers from both sides tried to persuade the public that precious liberty and self-government, hard-earned during the late Revolution, were at stake in the question. Anti-federalists such as the Federal Farmer, Centinel, and Brutus argued that the new Constitution would eventually lead to the dissolution of the state governments, the consolidation of the Union into “one great republic” under an unchecked national government, and as a result the loss of free, self-government. Brutus especially believed that in such an extensive and diverse nation, nothing short of despotism “could bind so great a country under one government.” Federalists such as James Madison (writing as Publius) countered that it was precisely a large nation, in conjunction with a well-constructed system of government, which would help to counter the “mortal disease” of popular governments: the “dangerous vice” of majority faction. In an extended republic, interests would be multiplied, Madison argued, making it difficult for a majority animated by one interest to unite and oppress the minority. If......

...Not ratifying the constitution would have been the better choice. Having a federal system where the sates are supreme makes is more beneficial to the people; having a strong central government however, leaves room for domination and control. The federalist supported the constitution and wanted a strong central government. As an anti-federalist the main focus of interest is the protecting the people's rights and limiting government control. Federalist supported the constitution, and wanted immediate ratification. They favored limiting state power, and believed that a strong central government was needed to protect the country. The Federalist's response to the anti-Federalist claim that a Bill of Rights should be introduced was that it would be dangerous. If a right was not listed, what was stopping the government from violating that law? The Federalist figured it would be best if no specific law was listed. Anti-Federalists did not want to ratify the constitution. Most Anti-Federalists believed that a somewhat stronger central government was needed, but for the most part favored a federal system where the states were supreme. Anti-Federalists did not want to ratify the constitution because there was no bill of rights, they wanted the rights of the people to be documented, and limit government power to some degree. The anti-federalist also believed that congress and the executive branch held too much power, and they feared that people of wealth would have the opportunity......

...Drug trafficking is an illegal drug trading system to which drugs are brought from other countries into the United States; to list just a few of these drugs; cocaine, heroin, hashish, marijuana, LSD, ecstasy, methamphetamines, and opiates. Terrorists are being funded by many of these drug trafficking operations in America. Another huge issue in The United States is the drug trafficking inside our country. In Florida and Texas, it is epidemic, the pill mills and grow houses are a major concern because they are supplying the entire United States with access to these drugs at a steady rate. As a result, there are many individuals and families that are being affected by addiction, illness, overdose, and death. The United States Government believes they have this under control and are helping to solve the situation, but in reality, drug trafficking in the United States is out of control. “Drug Trafficking is an activity that involves the cultivation, manufacturing, processing, importation and distribution of drugs” (Desroches, 2007). Going down the line of drug trade you have what is similar to an assembly line. You have the manufacturer or grower who grows and makes the actual drug which then is processed and packaged to be smuggled into the country. Eventually, making its way into America’s neighborhoods, by which is called the dealers. This is a process that has no end, because once one batch or shipment of drugs is distributed, there is already another on its way into America...

Regenerative Brake-Type Systems

...Regenerative Brake-type Systems Brian Seibert Miami-Jacobs Career College ATM-120 Abstract As I started brakes classes in college, I expected to be relearning all that I already knew about brake systems and how they work. How to do a brake job and how to identify a problem. Little did I know of how much technology has changed between the cars of today and the older cars ta I am used to repairing. When the concept of regenerative braking was explained by my teacher, I was blown away by the concept. As with all present day automotive systems, even braking has become computerized. The sensors, boosters, and even the connecting levers of the brake pedal itself has been replaced by an array of computers, sensors, and actuators to perform the same duties with less effort required of the driver. The latest brake-by-wire technology along with a deceleration tactic used by commercial drivers for decades has led to this leap in technology. For decades drivers have downshifted the transmission to use the engine RPM along with the taller (lower) gear to slow their trucks down from high speed. This method is commonly referred to as engine or trans-braking. The process jerks the engine and transmission, and is not a very comfortable ride for the vehicle's passengers. Engine braking has another downfall, it doesn't work very well on the automatic transmissions in passenger cars and can be detrimental to the health of the transmission. The smooth operation of the electric......

...money does come and go. One day your making really good money and the next thing you know you have lost almost everything and can’t even get a job at a simply diner. It’s sad to see this happen but like I said things do happen and with the right amount of guidance I think that the FPL can help those in much dire need. ‘’The poverty thresholds were developed in 1963 by Mollie Orshansky, an economist working for the Social Security Administration’’. (Orshancky 1970, p.235) Now her goal was not to introduce a new general measure of poverty but to measure the risk of low economic status. With federalism implementing itself in to these laws the government (not) the state controls the majority of the funding given out. ‘’Despite the federal anti-poverty programs 14.3 percent of all Americans lived below poverty threshold in 2009: that’s up from 14.2 percent back in 2008’’( Branham, Mary 2011, p28-31. 4p.) That not a huge different but there still shows a trend that needy families are not getting any better with time. Showing that only just 1.1 percent that the increase is not monumental but at the same time we also need to take a step back and readjust are position on poverty and are threshold to be able to fight this war on poverty. The pros of having the (FPL) is to see where Americans stand as a whole and to see if the American people are in need of ether A. a change or b. help. The cons of this program set in place are that a lot of people take advantages of the funds,......

Brake Systems

...Owners Chapter 2: BRAKING SYSTEM A brake is a mechanical device that retards or inhibits motion. It uses friction to convert the kinetic energy (moving cars etc.) into heat energy. There are two types of brakes: • Disc Brakes: The Disc Brake is a wheel brake that which slows rotation of a wheel by pushing brake pads against a brake disc with a set of calipers. Disc brakes are a less complex but more effective design of braking. • Drum Brakes : It is a type of brake where the friction is caused by a set of shoes or pads that press against rotating drum shaped part called brake drum. Two types of drum brakes are - Single leading edge (1 actuator) and Double Leading Edge (2 actuators). The advantage of using disc brakes over drum brakes is that they have better stopping performance including resistance to brake fade caused by overheating of brake components and are able to recover quickly from immersion. Even though asbestos is mostly used, today's brake pads are made out the following 1. Organic 2. Semi-Metallic 3. Metallic 4. Ceramic In a car, when the brakes are pressed, it transmits the force from the driver's foot to the brakes through a fluid. Since the actual brakes require a much larger force than the driver could apply with his leg, the car must also multiply the force of the driver's foot. It does this in two ways: • Mechanical Advantage (leverage) • Hydraulic Force Multiplication. In a hydraulic system, force applied at one point is......

...discourage the offender from repeating it. Locke concludes by noting that all people are in a state of nature until a special compact or agreement between them (which he promises to describe later) makes them members of a political society. Commentary In the Second Treatise, Locke rises above the specifics of the political situation described in the Introduction to outline a coherent theory of liberal political government, based on the sanctity of individual property and the state of nature. In Locke's state of nature, no person has control over another, natural law governs and renders all people equal, and every individual holds the executive power of natural law. Locke's theory includes many assumptions. First is the assumption of a system of morality--the natural law derives from a theory of justice, a set of rights. No one would have any "rights" at all in the absence of a moral code applicable to human actions, nor would there be any standard of "just" punishment. Locke frequently uses the term "rights" and appeals to conscience and "calm reason", all of which reflect his assumptions about justice and morality. Since this is our first encounter with the text, let's take this as an entry-point to talking a bit about Locke's writing itself, his syntax, word choice, and so on. Oddly enough, John Locke, the great Treatise writer and political philosopher, had a fairly cautious relationship with language. Book III of his very famous Essay Concerning Human......

Anti-Vaccination

...Professor Perez ENGL102 8 November 2015 The Anti-Vaccination Movement Over the last 30 years, the number of vaccine-preventable diseases has increased substantially. This is due to a rising number of “anti-vaxxers” spreading misinformation “that vaccines are actually ineffective, useless, or even dangerous” (Kata 3778). The internet and other forms of mass media have steered parents to believe these claims and it has had devastating results. It has been proven by scientists for hundreds of years that the use of vaccinations greatly outweighs the risk of not getting them. The research shows that the claim that vaccines cause autism or any other disease cannot be substantiated by any scientific evidence and therefore, should not be entertained under any circumstances. The background of the anti-vaccination movement is an old one. The United Kingdom’s Vaccination Act of 1853 is a good example of this. The act required parents to vaccinate their children for small pox at three months or risk life in prison. This is a harsh punishment for the parents, but considering the millions of deaths that small pox has caused world-wide, lawmakers at the time considered it a just penalty. “The anti-vaccination movement experienced a steady decline from the turn of the century up to the 1970's” (Kasarda 548). After the 1970’s there was a resurgence in the anti-vaccination movement. This is due to research from a group of authors working at London Hospital. “M. Kulenkampf, J.S.......
