The unbalanced wheel(disk) rolls without slipping down the inclined surface. The wheel weighs 32.2-lb and has a radius of gyration of 4.25 inches with respect to its axis of rotation. When the wheel is in the position shown, it has an angular velocity of 5 rad/s counterclockwise. For this instant, find: a) angular acceleration of the wheel, b) normal and frictional forces exerted on the wheel by the incline. NOTE: For the numeric answer type in the angular acceleration to no decimal. 3 in. 6 in. 3. The unbalanced wheel(disk) rolls without slipping down the inclined surface.
