In an emergency situation, a person with a broken forearm ties a strap from his hand to clip on his shoulder . His 1.60-kg forearm remains in a horizontal position and the strap makes an angle of ? = 51.5° with the horizontal. Assume the forearm is uniform, has a length of l = 0.312 m, assume the biceps muscle is relaxed, and ignore the mass and length of the hand.
(a) find the tension in the strap (N)
(b) Find the components of the reaction force exerted by the humerus on the forearm.
