Question

Problem 3. The grooved pulley of mass m is acted on by a constant force F through a cable, which is wrapped securely around the exterior of the pulley. The pulley supports a cylinder of mass M, which is attached to the end of a cable, which, in turn, is wrapped securely around an inner hub. If the system is stationary when the force F is first applied, determine the upward velocity of the supported, mass after 3s. Use the values $m = 40 kg$, $M = 10 kg$, $r_o = 225 mm$, $r_i = 150 mm$, $I_o = 25600 kg mm^2$, and $F = 75 N$. Assume no mechanical interference for the indicated time frame and neglect friction in the bearing at O. What is the time-averaged value of the force in the cable that supports the 10-kg mass?
