BEHAVIOUR OF METALS – PROBLEM FOR HEAT TRANSFER FROM THE AUTOMOBILE BRAKES SYSTEMS

Porag Kalita

Abstract: We know that, The Braking action is the use of a controlled force to reduce the speed or to stop a moving vehicle or to keep a vehicle stationary , when braking is applied, it develop friction which does the braking i.e. Kinetic energy which is converted into heat energy on the application of brake. The biggest question today is, while the driver is going to brake applied, this force is increasing by 8 times of as per horse power. For example, one vehicle has 100 hp, after the braking applied is going to reached 800 hp. Therefore, in terms of behavior of metals, some time frequent accident by means of dragging. Because, this heat is transferred through the surrounding air. The weight of the vehicle is divided on its axle, and retarding force acts on the point of road contacts towards the rear and the inertia force of gravity towards the font. Let F= retarding force, µ = coefficient of friction, W = weight of the vehicle, h = height of centre of Gravity of the vehicle from road. Therefore

Keywords: Braking action, horse power, inertia
