Question

The 50-kg flywheel has a radius of gyration about its center of mass of ko= 250mm. It rotates with a constant angular velocity of 120rev/min before the brake is applied. If the coefficient of kinetic friction between the brake pad B and the wheel’s rim is ?k= 0.5, and a force of P = 300 N is applied to the braking mechanism’s handle, determine the time required to stop the wheel.
