Physics
A worker lifts a weight w by pulling down on a rope with a S force F. The upper pulley is attached to the ceiling by a chain, and the lower pulley is at- tached to the weight by another chain. Draw one or more free-body diagrams to find the tension in each chain and the magnitude of S F, in terms of w, if the weight is lifted at constant speed. Assume that the rope, pul- leys, and chains have negligible weights.
