Figure P5.62 5.62 - In Fig. P5.62 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. Draw one or more free-body diagrams to find the tension in each chain and the magni- tude of F, in terms of w, if the weight is lifted at constant speed. Assume that the rope, pulleys, and chains have negligible weights.
