pulley system is used to lift a crate of mass m = 58 kg. Note that a chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. Assume that the masses of the chains, pulleys, and ropes are negligible
(a) Determine the force F required to lift the crate with constant speed.
....N
(b) Determine the tension in the upper chain.
....N
(c) Determine the tension in the lower chain.
