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...

Problem (3) A motor M and a frictionless pulley-cable system are used to lift the 850 lb crate shown at a constant acceleration. The motor has an efficiency of E = 0.6 and the input power to it is 92 hp at the instant when the load has been hoisted s = 15 ft starting from rest. Determine the tension force in the cable. Neglect the mass of the pulleys and cable.
