The pedal and brake drum are illustrated in Figure Q2(b). The 160 mm radius
brake drum is attached to a larger flywheel (not shown). The total mass moment
of inertia of the flywheel and drum is 20 kg-m? and the coefficient of kinetic
friction between the drum and the brake shoe is 0.35. The initial angular velocity
of the flywheel is 360 rpm counterclockwise. If the system is to stop in 100
revolutions, determine the vertical force P that must be applied to the pedal C.
(Hint: Draw a free-body diagram for the brake drum and pedal, separately and
label all the forces)
