A man is holding a 2.80-kg ball, as shown in the figure. The distance from the elbow joint to the ball is d= 32.5 cm, and the distance from the elbow joint to the insertion of the triceps muscle is d= 2.50cm. The mass of the lower arm, including the hand, is 3.60 kg, and its center of gravity is at a distance d= 13.6cm from the elbow joint. a)Draw a free body diagram of the forearm. b)What is the magnitude of the force FM, exerted by the triceps? c)What is the force exerted by the humerus on the elbow joint?
