Problem 3.5 Consider a person using an exercise apparatus
who is holding a handle that is attached to a cable (Fig. 3.31).
The cable is wrapped around a pulley and attached to a weight
pan. The weight in the weight pan stretches the cable and
produces a tensile force F in the cable. This force is transmitted
to the person's hand through the handle. The force makes an
angle 0 with the horizontal and applied to the hand at point
B. Point A represents the center of gravity of the person's lower
