5. For the free body diagram of the forearm and hand shown below, calculate the biceps muscie force, Fm, and the x- and y-components of the elbow joint reaction forces, Fx and Fy. The forearm is 35° below the horizontal and E- makes an 80° angle with the horizontal as shown. The load in the hand, L, is 20 lbs and the weight of the forearm and hand, W, is 4 lbs. 1he distance from the elbow to the musele origin EO is 2 in, to the center of mass of the forearm and hand, EW, is 7 in and to the load in the hand, EL, is 15 in. Fm Fy 80 E Ft 35°
