The double pulley shown has a mass of 15 kg and a centroidal radius of gyration of 160 mm. Cylinder A and block B are attached to cords that are wrapped on the pulleys as shown. The coefficient of kinetic friction between block and the surface is 0.2. Knowing that the system is at rest in the position shown when a constant force P = 200 N is applied to cylinder A , determine (a ) the velocity of cylinder A as it strikes the ground, (b ) the total distance that block B moves before coming to rest.
The 8-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 is
15 lb.ft.s2 and the coefficient of kinetic friction between the drum and
the brake shoe is 0.40. Knowing that the angular velocity of the flywheel
is 450 rpm clockwise when a force P of magnitude 65 lbf. is applied to
the pedal C, determine the number of the revolutions executed by the
flywheel before it comes to rest.
