The 200-mm 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 20 kg-m² and the coefficient of kinetic friction between the drum and the brake shoe at B is 0.35. Knowing that the angular velocity of the flywheel is 360 rpm counterclockwise when a force P of magnitude 350 N is applied to the pedal C, determine the number of revolutions executed by the flywheel before it comes to rest. 150 mm 250 mm 200 mm B 375 mm

Question
The 200-mm 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 20 kg.m² and the coefficient of kinetic friction between the
drum and the brake shoe at B is 0.35. Knowing that the angular velocity of the flywheel is 360 rpm
counterclockwise when a force P of magnitude 350 N is applied to the pedal C, determine the number of
revolutions executed by the flywheel before it comes to rest.
