You hold a 1.80-N softball in your hand as shown in the figure. Consider your forearm and hand to be a uniform rod with a mass of 1.35 kg and the distance between the elbow joint and the ball in your hand is 2L = 30.0 cm. Your biceps exerts an upward force of 13.0 N on the forearm and is attached at a distance of d = 3.20 cm from the elbow. Using the elbow joint as the axis of rotation, determine the magnitude of the net torque acting about the elbow due to the forearm, hand, and ball.
