Chapter 17, Problem 73P
Cable is unwound from a spool supported on small rollers at A and B by exerting a force T= 300 N on the cable. Compute the time needed to unravel 5 m of cable from the spool if the spool and cable have a total mass of 600 kg and a radius of gyration of kO = 1.2 m. For the calculation, neglect the mass of the cable being unwound and the mass of the rollers at A and B. The rollers turn with no friction.

A man pushes bar CD to either initiate uphill motion of the homogeneous spool or to just keep the homogeneous spool from moving downhill. The spool has mass M = 78 kg. If slippage first occurs at B, calculate the smallest force P in N that the man must apply to the bar CD to initiate uphill motion of the spool and If slippage first occurs at A, calculate the smallest force P in N that the man must apply to the bar CD to initiate uphill motion of the spool.
The force F 250 N is applied to a wheel weighing 20 kg and having a radius of inertia of 150 mm as shown in the figure. This force lifts a weight B of 10 kg. Calculate the angular acceleration of the pulley and the normal acceleration of the weight B, the tension of the rope and the reaction in the bearing of the pulley.
