Chapter 5, Problem 5.3.43(choose chapter or problem)
The system shown in Figure P5.43 is used to lift an object of mass m 5 76.0 kg. A constant downward force of magnitude F is applied to the loose end of the rope such that the hanging object moves upward at constant speed. Neglecting the masses of the rope and pulleys, find (a) the required value of F, (b) the tensions T1, T2, and T3, and (c) the work done by the applied force in raising the object a distance of 1.80 m.
