Homework Answers
In cord Z, tension is greatest. This is because the cord Z is used in pulling all the other four boxes, that's why this cord will experience maximum tension in the backwards direction.
However, the cord W will experience the lowest tension as this cord is used in pulling a single box only.

The fiqure shows a man sitting in a bosun's chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of man and chair is 78.4 kg. With what force magnitude must the man pull on the rope if he is to rise (a) with a constant velocity and (b) with an upward acceleration of 1.42 m/s2? (Hint: A free-body diagram can really help.) Problem continues below...
