3. During tug of war, the bicep muscle generated 4k N force that was perpendicular to the forearm bone. The bicep muscle was attached 4 cm from the elbow joint as shown in figure below. (a) Compute the bending moment at section a-a (b) If a circular solid bone with allowable compressive stress of 130 MPa, what is the minimum permissible radius of the bone?
