A 120-lb weight is attached to the cable that is wrapped around the 50-lb homogeneous drum. The shaft attached to the drum is supported by a thrust bearing at A and a slider bearing at B. The drum is kept in equilibrium by the vertical force P acting on the handle of the crank. Determine P and the reactions at A and B. Neglect the weights of the crank and the shaft.
