The 8-in. radius brake drum is attached to a larger flywheel that is not shown. The total mass moment of inertia of the drum and the flywheel is 15 lb.ft.s2 and the coefficient of kinetic friction between the drum and the brake shoe is 0.40. Knowing that the angular velocity of the flywheel is 450 rpm clockwise when a force P of magnitude 65 lbf. is applied to the pedal C, determine the number of the revolutions executed by the flywheel before it comes to rest. (The final answer should be in two decimal places with correct units)

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.
