HER In an emergency situation, a person with a broken forearm ties a strap from his hand to clip on his shoulder as in the figure below. His 1.60-kg forearm remains in a horizontal position and the strap makes an angle of 0 = 49.0 with the horizontal. Assume the forearm is uniform, has a length of { = 0.316 m, assume the biceps muscle is relaxed, and ignore the mass and length of the hand. R (a) Find the tension in the strap. N (b) Find the components of the reaction force exerted by the humerus on the forearm. (Assume the positive x-direction is to the right and the positive y-direction is upward.)
