QUESTION:

Mechanical Advantage The pulley system shown in Figure 6–22 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. Assuming the masses of the chains, pulleys, and ropes are negligible, determine (a) the force required to lift the crate with constant speed, (b) the tension in the

upper chain, and (c) the tension in the lower chain.
