Question

A 10 lb uniform thin bar BC of length L = 10 ft is pinned at B to the edge of a 20 lb uniform disk of radius R = 3.5 ft. The system is initially at rest in the position shown when a constant horizontal force P = 60 lb is applied to the end C. Assume that the disk rolls without slip. In addition, neglect the friction between the end C of the bar and the ground, as well as the friction at the pin. Determine the angular speed of the disk when point B is directly above the center of the disk. Hint: To determine the displacement of point C, keep in mind that the overall displacement of point A is ?R?2.
