Arm wrestlers can develop their muscles, but they can only do so much to strengthen their bones. The force exerted on the hand causes torsion of the humerus. Let us assume the cross-section of this wrestler's humerus is approximated as hollow (the marrow has little structural strength) with an outer diameter of 19.0 mm and an inner diameter of 15.0 mm. The length of the humerus is 360mm. Also, assume that the whole twisting moment is taken by the bone. If the humerus can withstand a shear stress max = 70.0 MPa , determine the maximum force the hand can apply without fracturing the humerus.
