Brakes may be one of the most essential inventions in the developments of automobiles. Clearly, nothing can surpass the breakthrough of the wheel, but the brake system was a catalyst to the further developments of cars. The brake system has also evolved greatly throughout the years. Once considered one of the simplest parts of a vehicle, brakes have become one of the most complicated components in a vehicle. The scientific explanation behind a brake system is very rudimentary. Friction permits the concept of braking to occur.
The first brake system was used thousands of years ago. The Romans had a system that involved a wooden block and a lever to slow and stop the cart. The driver would push or pull the lever which causes a wooden block to be pressed against the outer part of the wheel. These were used until the 20th century. Later the drum and disc brakes were invented to accommodate the faster motorized automobiles. The drum brake is placed in the inner surface of the wheel. When the brake is applied, the brake shoes will move outward and create friction against the drum. In the disc brake, there are more components to it. There is a rotor that is attached to the wheel and a caliper. The rotor is a disc which rotates with the wheel. The caliper squeezes on the rotor when the brakes are pressed instead of rubbing directly against the wheel. Disc brakes are sometimes preferred to drum brakes because of its superior cooling system. When the brake pads rub against the rotor or drum, heat is also produced. It is harder for the drum brakes to cool down because it is located inside the wheel and not exposed to as much outside air. Some disc brakes will have slits on the sides of the disc to provide cooling. Faster cooling will pre...

...ads. The theory behind this is that a non-rotating tire has less traction than a spinning one. The ABS will allow the vehicle to stop faster than when the wheel is skidding and allow the driver to remain in control of the vehicle while it stops. With the technology today, there are sensors attached to the wheels to sense when one wheel is spinning at a different speed than another.
The brake system is something that the driver should always check to be working properly. Once the driver feels that the brakes are not working optimally, he or she should bring it to a maintenance shop to replace the brake pads, rotor, disc, or drum. The tire also is a factor to how quickly a car will stop. Keeping key components in your car in check at all times will help make anyone a better driver. Having a well working brake system will make the roads safer for everyone in the HTS.
“‘They score! Henderson has scored for Canada!’” Foster Hewitt wordlessly described” (Pelletier) when Paul Henderson scored the series-winning goal. This allowed Canada to win the 1972 Summit Series, a moment that no one would ever forget since it all happened during the climax of the Cold War. Prior to this, the Soviets had won the previous three Olympic gold metals since Canada could not use its NHL players. Thus, this provided Canada with the chance to play hockey against the USSR using its best players. This raised the question: if Canada were able to send its best players, would it still be enough to beat the Soviets? Everyone in Canada was certain that the Soviets would not win a single game, but little did they know they underestimated the extent of the Soviets abilities. Tied in the last few minutes of game eight, Canada had to score or they would lose the series. However, when Paul Henderson scored the game-winning goal, never before had a single sporting event meant so much to Canadians. Therefore, Paul Henderson’s goal is a defining moment for Canada in the twentieth century becauseit provided Canada with the opportunity to evolve hockey, proved that Canada and our democratic society were superior to the USSR and their communist society, and brought citizens together to unify Canada as a nation.
The Hunger Games was a critically acclaimed movie when it came out; however, some critics would argue that the movie can be sometimes too violent for its intended audience. In this essay I would dissert Brian Bethune’s essay “Dystopia Now” in order to find its weaknesses and compare the movie Battle Royale with his essay.
The best model of motor vehicle is the Cadillac because it is characterized by advanced technological model enhancing the motor vehicle’s efficiency. This advanced technology makes the Cadillac a classic model of motor vehicle. The anti-locking brakes of this vehicle enable the wheels to co-ordinate well in order to give the vehicle stability. There is also a sensor that is installed at each wheel of the Cadillac. The work of this sensor is to gauge the pressure exerted by the brakes. This vehicle’s pressure is subject to the capability of the system to produce heat. The sensor and the anti-locking system serve to maintain wheel balancing.
Scott Hightower’s poem “Father” could be very confusing to interpret. Throughout almost the entirety of the poem the speaker tries to define who his father is by comparing him to various things. As the poem begins the reader is provided with the information that the father “was” all of these things this things that he is being compared to. The constant use of the word “was” gets the reader to think ‘how come the speaker’s father is no longer comparable to these things?’ After the speaker reveals that his father is no longer around, he describes how his father impacted him. Details about the father as well as descriptions of the impacts the father has distraught on the speaker are all presented in metaphors. The repetitive pattern concerning the speaker’s father and the constant use of metaphors gives the reader a sense that the speaker possesses an obsessive trait. As the reader tries to interpret the seemingly endless amount of metaphors, sets of connotative image banks begin to develop in the reader’s mind. Major concepts that are expressed throughout the poem are ideas about what the speaker’s father was like, what he meant to the speaker, and how he influenced the speaker.
Other signs of brake issues include the brake pedal traveling closer to the floorboard than usual, or a sinking pedal going to the floor both indicate prompt brake repair is needed. Other signs of brake issues include pulling, pulsing, or “chattering”, and low brake fluid. Worn brakes often result in low brake fluid. Never drive a vehicle with suspected brake problems, and don’t ignore the brake, or the ABS warning light. Be alert for changes in braking and have it checked when they occur. Contact Fifth Gear Automotive auto repair shops Lewisville, TX to schedule break repair.
In short brakes are a tool that turn kinetic energy into heat(http://en.wikipedia.org/wiki/Brakes). This is accomplished by applying friction in one way or another. In the case of disk brakes friction is created because the braking mechanism exerts a force on the break pads which pushes them into contact with disk. It is this contact combined with the fact that the disks are rotating that causes kinetic energy to be converted to heat.
Vehicles are a main necessities of our life, it have been with us for quite a long period; it is time efficient, but the number of death it have caused is not easily avoided; therefore the engineers have designed vehicle safety features such as seat belts and crumple zones regarding the concepts of Newton’s Laws of Motion to help save our lives.
Disc brakes are the most recent instalment in bicycle braking. A metal disc is attached directly to the hub of the wheel, which rotates accordingly. Callipers which are connected to the fork or frame of the bicycle clamp onto the disc, which slows the rotation of the wheel. Disc brakes can be either mechanically, hydraulically triggered or a combination of both. Mechanically triggered brakes work similar to the previous cable actuated brakes spoken about in this report. A lever arm attached to the handlebars is applied a force which stretches a Bowden cable and engages the braking callipers. Hydraulically triggered disc brakes consist of a fluid within the braking system opposed to a cable. When the lever arm is engaged, the fluid is pressurised, and applies a force to pistons attached to the braking callipers.
There are many social problems that exist in the world today, which includes but do not limits to self-identity and racism. However, they somehow go unnoticed because at times people conform to what society thinks is the way to live. In my opinion, people believe they should act or feel a certain way because of what is broadcast on television, featured in magazines, and even brought into the limelight by celebrities. After viewing the movie Crash, in my opinion, the movie targets on going social problems that are constantly being swept under the rug to this present day. I deem Crash a race movie because it forces the audience to question their own moral values.
Cars are large objects of great mass which can reach very fast velocities, this can be a dangerous combination if the physics aren’t correct. Seeing as there is over 1.2 billion cars world wide, physicians have put much detail into aspects of cars to make them as safe as possible. In the paragraphs below I will be be briefly discussing different aspects of the everyday automobile and its safety.
This paper is a look at the physics behind car racing. We look look at how we can use physics to select tires, how physics can help predict how much traction we will have, how physics helps modern cars get there extreme speed, how physics lets us predict the power of an engine, and how physics can even help the driver find the quickest way around the track.
Over the years, cars have advanced from a very basic and functional piece of technology to a high speed and intelligent set of interrelated components. Cars play a big part in our world and have changed a lot over the years.

In designing a railway wheel, the important thing that must be considered is material used. Choosing the right material will give a better result to the performance and the condition of the wheel. It is believed that most of the problems that occur to the railway wheel are the result from the thread braking, which is known as non-uniform heating. Thermal loading has the ability to initiate cracks, increase the crack growth rate and also reverse the residual stress in the rim. For the railway operation, there are two types of braking that involves in the operation which are stop braking and drag braking. Stop braking is used during the emergency time. Another one is drag braking, used to slow the train over a long distance, to ensure that the speed is under the control. In stop braking condition, thermal fatigue cracks will initiate and propagate while under the drag braking condition, an extreme thermal input occurs which can fracture the wheel. When the brakes are applied for long periods of time, it will cause the heating of the thread and rim of the wheel, generated by frictional forces. Observation of the railway wheel has been made based on the wheels in Keretapi Tanah Melayu (KTM) Padang Besar, found that there is no crack occur except the scratch. This also happens due to the braking. Aside from friction heat result from the brake application, crack may also initiate and propagate due to the impact load that has been applied to the wheel. For each of different size of wheels, there is limitation for the load. It is important to understand the basic modes of fracture that are enable a crack to propagate. The three modes are opening mode (mode I), in-plane-shear (mode II) and out-of-plane-shea...
