Break drum and flywheel
The 8-in.-radius brake drum is attached to a larger flywheel that is not shown. The total mass moment of inertia of the flywheel and drum is 14 lb·ft·s2 and the coefficient of kinetic friction between the drum and the brake shoe is 0.35. Knowing that the initial angular velocity of the flywheel is 410 rpm counterclockwise, determine the vertical force P that must be applied to the pedal C if the system is to stop in 100 revolutions.

An aluminum flywheel (density=2.7g/cm^3) has a radius of 1.5m and moment of inertia 25kg. The flywheel is initially spinning at 1200 rpm, and is to be stopped by a friction brake that runs on the curved outside surface. If the coefficient of friction is 0.600, how hard must the brake be pushed onto the flywheel to bring it to rest in 4.0s?

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.
