A winding drum raises a cage of mass 500kg through a height of 100m. The mass of the winding drum is 250kg and has an effective radius of radius of 0.5m and radius of gyration is 0.35m. The mass of the rope is 3kg per cubic meter. The cage has, at first an acceleration of 1.5meters per square second until a velocity of 10m/s is reached, after which the velocity is constant until the cage nears the top and the final retardation is 6m per square second. Find
(a) The time taken for the cage to reach the top?
(b) The torque which must be applied to the drum at starting?
(c) The power at the end of acceleration period?
