The pulley system shown in the figure is used to lift a 52-kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. Assume the masses of the chains, pulleys, and ropes are negligible.

Determine the force F required to lift the crate with constant speed

Determine the tension in the upper chain.

Determine the tension in the lower chain.
