dynamics- work-energy principle for rigid bodies

Project Description:

a 10 lb uniform thin bar bc of length l=10 ft is pinned at b to the edge of a 18 lb uniform disk of radius r= 3.2 ft. the system is initially at rest in the position shown when a constant horizontal force p= 57 lb is applied to the end c. assume that the disk rolls without slip. in addition, neglect the friction between the end c and the bar and the ground as well as the friction at the pin. determine the angular speed of the disk when point b is driectly above the center of the disk. hint: to determine the displacement of point c eep in mind that the overall displacement of point a is pir/2.
