Answer: In Fig. P5.62 a worker lifts a weight w by pulling
Chapter 5, Problem 5.62(choose chapter or problem)
In Fig. P5.62 a worker lifts a weight w by pulling down on a rope with a force \(\overrightarrow{\boldsymbol{F}}\). 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 magnitude of \(\overrightarrow{\boldsymbol{F}}\), in terms of w, if the weight is lifted at constant speed. Assume that the rope, pulleys, and chains have negligible weights.
