You hold a ball in the palm of your hand, as shown in Figure 12.10. The bones in your forearm act like a horizontal lever pivoted at the elbow. The bones are held up by the biceps muscle, which makes an angle of about \(15^{\circ}\) with the vertical. Draw an extended free-body diagram for your forearm.
