14 pt) The measurements in the figure are made on the forearm. The forearm is hung vertically and 90? from the upper arm at the elbow. The two spring scales are pulled along horizontal direction, and the arm is in static equilibrium.a) If the distance from the elbow to the bicep attachment point is 5.0 cm, and the scale attach to the bicep attachment point reads 4.5 N, what is the torque due to the "biceps muscle" on the elbow?b) What is the distance from the elbow joint to the wrist joint (where the scale reading is 1.5 N)?c) Assume the skeleton forearm weights 4.0 N, draw and label all the forces applied to the forearm, and find out the magnitude and direction of the force the upper arm applied to the forearm at the elbow joint.
