Transcribed Image Text:6. 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.s? 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 360 rpm counterclockwise, use the Principle of the
Energy Methods for Rigid Body to determine the vertical force P that must be applied
