Hi can anyone help me please. A cage of mass 2 tonne is to be raised from the bottom of a mine shaft with a starting acceleration of 1.31.7 m/s2. The hoisting cable passed round a winding drum of mass 802902 kg and a diameter of 1.21.6 m. Assuming that the mass of the winding drum can be taken to be concentrated at its outside radius and that friction is negligible on the drum but a constant frictional force of 801901N act on the cage. (a) Calculate the total starting torque at the winding drum shaft. (b) When the inertia forces are overcome the cage travels at a constant velocity of 1.5 m/s, determine the workdone and the power required to lift the cage through a distance of 16m. Assume frictional forces remain the same.
