The crane is lifting a180 kg crate upward with the acceleration of 1.2. The cable from crate passes over a solid cylindrical pulley at the top of the boom.The pulley consists of a mass of 130 kg.The cable is the wound to a hollow cylindrical drum which is mounted on the deck of the crane. The mass of drum is 150 kg and its radius is 0.76m. Determine the magnitude of the torque the engine applies to the drum? Avoid the mass of the cable.
