Advantages And Disadvantages Of Brake

The same can be said for automobiles—the tires rely on friction with the concrete or asphalt in order to move. In this case, as the kicker approaches the football, it is friction that is responsible for the movement. Friction, by definition, is a force of resistance to relative motion between two bodies or substances in physical contact.

The development and use of the disk brakes was fist in England in the 1980’s. Frederick William Lanchaster was the first guy that patented the first ever caliper-type disk brake in his Birmingham factory in 1902 and it was used successfully on his Lanchaster cars. He struggled to keep up the maintenance of a quality brake because of the limited choice of metals in the period of time. Causing him to use copper as the braking medium acting on the disk. However, due to the bad road conditions, it didn’t allow copper to last very long because copper can wear out easily, making the disk brake system non-viable.

You use it to slow the car and to stop the car. As pointed out before, you should use the engine to slow the T but at some point when you need to stop, you must release the clutch pedal halfway or all the way (depending on the position of your hand brake/high gear lever) and then step on the right brake pedal. Because of the three pedals, the brake is used the most, it pays to use the engine to slow the car. As we will point out next, using the reverse pedal to slow the car to save brake

The majority of movement of materials and goods across continents is through container ships, however, in some cases, planes are used to transport goods. Trucks and trains move materials and goods and within a country or a continent. In some cases, ships sail in rivers, as is the case in parts of Canada. The shares of freight transport as the percentage of the total tone-km by road, inland waterways, and railways in the EU are 75.9%, 6.7%, and 18.4% respectively (EUROSTAT, 2016). In the USA, trucks are the most used means of transportation for moving freight up to 750 miles. Trains move items in bulk beyond the 750-mile limit up to 2000 miles (United States Department of Transportation, 2015).

Oil or grease on the brakes can cause brake failure because it interferes with friction. Also, when the brakes overheat to a high degree, the metal develops spots. These spots resist friction from the brake pads, which leads to a loss of brake

Friction allows the car’s wheels to spin across the floor without just sliding across the floor. Friction is also present in the gear box of the toy car. Friction is present because the gears have to rotate against each other in order for the toy car to obtain potential energy. The toy car only produces rolling friction, which is present when the wheels rotate against the floor. Rolling also appears in the gearbox. Friction while not energy affects the energy in the toy car in two ways. Friction causes kinetic energy to be lost while the car is moving. Kinetic energy is lost when the wheels rotate against the floor because the wheels are using kinetic energy to move. The energy is then lost when because of rolling friction heat is produced. In a shorter sense the wheels because of friction convert some of the kinetic energy into thermal energy (heat). Energy is also lost when the gears in the gear box rotate against each other. Some energy would be lost because of the friction of the gears some potential energy would be converted to thermal energy affect making less potential energy available. While friction causes a loss to energy, rolling friction allows less work to be able to overcome friction (“About Friction”, 2003). Friction while not energy plays a part in both energies that affect the toy car.

Various modern equipments and processing methods are used for the manufacturing of new type of brakes. Some of them are Computer Numerically Controlled (CNC) machines, Laser cutting machinery and Chemical processing (anodize and conversion coating).

Electric motor - The electric motor on a hybrid car is very sophisticated. Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries.

The reason for the development of anti-lock braking system is very simple. Under braking, if one or more of a vehicle’s wheels lock then this has a number of consequences: a) braking distance increases, b) steering control is lost, and c) tire wear will be uncommon. The tangible outcome is that an accident is more likely to occur. The application of brakes creates a force that impedes a vehicles motion by applying a force in the opposite direction. During severe braking scenarios, a point is obtained in which the tangential velocity of the tire surface and the velocity on road surface are not the same such that an optimal slip which corresponds to the maximum friction is obtained. The ABS controller must deal with the brake dynamics and the wheel dynamics as a whole plant.

This report consists of the literature review on the advancement and evolution of braking technology. The report focuses on the need on advancement and the solution found as Eddy current braking. It also explains the working of the eddy current brakes and the advantages and disadvantages of its uses. The scope and the future aspects of eddy current brake systems is discussed in the report.
