The 10-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 about point Cis 15

Ib-ft-s2, and the coefficient of kinetic friction between the drum and the brake shoes is 0.35. When the hydraulic cylinder Fis actuated, it exerts a force of 30 lb directed to the right on point Band to the left on point E. The angular velocity of the flywheel is 360 rpm counterclockwise when Fis actuated. Determine the number of revolutions executed by the flywheel before it comes to rest. The number of revolutions executed by the flywheel before it comes to rest isrev.
