FIGURE 1 FIGURE 1 shows a horizontal human arm lifting a dumbbell. The forearm is in equilibrium under the action of the weight W of the dumbbell, the tension T in the tendon connected to the biceps muscle, and the force E exerted on the forearm itself. (For clarity, the point A where the tendon is attached is drawn farther from the elbow than its actual position) Given the weight of the forearm is 20 N and the mass of the dumbbell is 20 kg. The angle between the tension force and the horizontal, 0 is 80°. The length of the horizontal arm is 0.30 m. The horizontal distance between elbow pivot and point A is 0.050 m. Find T and the vector E and draw free body diagram for this case.
