The crane shown in the figure is lifting a 463-kg crate upward with an acceleration of 2.60 m/s2. The cable from the crate passes over a solid cylindrical pulley at the top of the boom. The pulley has a mass of 111 kg. The cable is then wound onto a hollow cylindrical drum that is mounted on the deck of the crane. The mass of the drum is 124 kg, and its radius (the same as that of the pulley)...
