Answer to Question #8572 in Mechanics | Relativity for Shadrack

Question #8572
the160 mm radius brake drum is attached to a large flywheel that is not shown. the mass and radius of gyration of the drum and flywheel together are 1152kg and 125mm, and the coefficient of kinetic friction between the drum and the brake shoe is 0.35. knowing that the angular velocity of the flywheel is 360 rpm anti-clockwise when a force P of magnitude 300N is applied to the pedal C, determine a) The normal frictional force acting on the brake drum at B? b) The angular acceleration of drum when the force is applied? c) The number of revolutions executed by the flywheel before it comes to rest?
