A truck weighing 200kN descends a 250m hill with brakes engaged at a constant speed. These brakes can withstand an 18 deg C increase in temperature safely. Consider that the brakes retain 22% of the energy from the descending truck. Will the brakes be expected to fail? ( mass of brakes = 200kg, specific heat of brake material = 1050 J/kgC)

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.
