Question

A 71.0 kg weight lifter is doing arm raises using a 7.50 kg weight in her hand. Her arm pivots around the elbow joint, starting 40.0 below the horizontal. (See the figure(Figure 1) .) Biometric measurements have shown that both forearms and the hands together account for 5.90 % of a person's weight. Since the upper arm is held vertically, the biceps muscle always acts vertically and is attached to the bones of the forearm 5.50 cm from the elbow joint. The center of mass of this person's forearm-hand combination is 15.5 cm from the elbow joint, along the bones of the forearm, and the weight is held 38.0 cmfrom the elbow joint.
