Question

The pulley system shown in the figure (Figure 1) is used to lift a 52- kgcrate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. The crate is rising with an acceleration of 3.0 m/s^2 a.) Assuming the masses of the chains, pulleys, and ropes are negligible, determine the magnitude of the force F b.) Determine the direction of the force F Upward or Downward? c.) Determine the tension in the upper chain. d.) Determine the tension in the lower chain.
