Express your answer using two significant figures. ANSWER:   Clower =   kN   ANSWER:   Clower =   kN     Clower =   kN     F =   kN   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.

Explanation / Answer

1.)Determine the force F required to lift the crate with constant speed.

Since this is a pulley system, we have to count the number of
