The 12-lb uniform disk shown, of radius r=3.2 in., rotates counterclockwise. Its center C is constrained to move in a slot
cut in the vertical member AB, and an 11-lb horizontal force P is applied at B to maintain contact at D between the disk and
the vertical wall. The disk moves downward under the influence of gravity and the friction at D.
