In Fig. 5.60 a worker lifts a weight w by pulling down on a rope with a force F. The upper pulley is attached to the ceiling by a chain, and the lower pulley is attached to the weight by another chain. In terms of w, find the tension in each chain and the magnitude of the force F if the weight is lifted at constant speed. Include the free body diagram or diagrams you used to determine your answers. Assume that the rope, pulleys, and chains all have negligible weights.
