..The pulley system in Figure 6 is used to lift a 52-kg crate. Note that a 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, de- termine (a) the force F required to lift the crate with constant speed and (b) the tension in each chain. CO000 3oodg F
