The power of an engine running at 125 rpm is turned off and the engine comes to rest at the end of 2 min and 40 sec. Assuming that there is no slipping between the belt and pulley surface and that the deceleration is uniform, find 1) the average speed in radians per second of the engine pulley in coming to rest; 2) the total angular distance traveled in revolutions, radians and degrees in coming to rest; 3) the distance in feet traveled by a belt running on the pulley in coming to rest, if the pulley diameter is 3ft.

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.
