A commercial crane hook has the cross-sectional dimensions shown in Figure P9.10 at the critical section that is subjected to an axial load P = 100 kN. Determine the circumferential stresses at the inner and outer radii for this load. Assume that area A1 is half of an ellipse [see row (j) in Table 9.2] and area A3is enclosed by a circular arc.
