See attached file for full problem description with diagram.
5-60 In Fig. 5-48 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.
