The 10-in.-radius brake drum is attached to a larger flywheel that is not shown. The total mass
Question:
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 C is 15 lb·ft·s2, and the coefficient of kinetic friction between the drum and the brake shoes is 0.35. When the hydraulic cylinder F is actuated, it exerts a force of 30 lb directed to the right on point B and to the left on point E. Knowing that the angular velocity of the flywheel is 360 rpm counterclockwise when F is actuated, determine the number of revolutions executed by the flywheel before it comes to rest.
