A patient in therapy has a forearm that weighs -20.5 N and that lifts a -112 N weight. These two forces have direction vertically downward. The only other significant forces on his forearm come from the biceps muscle and the force at the elbow. If the biceps produces a pull of 232 N when the forearm is raised above 43 degrees the horizontal, find the magnitude and direction of the force that the elbow exerts on the forearm. (Take note that the sum of elbow force and biceps force must balance the weight of the arm and the weight it is carrying, so their vector sum must be 132.5 N upward).
