A hook is fashioned by bending a 8.0 mm wide metal bar into the shape shown. A force of 85 N is applied at D. The strength of the metal limits both the shear stress and the bending stress to 70 MPa. Determine the dimension 'a' of the bar such that the strength is not exceeded. Your solution must demonstrate that the bar is safe for both bending stress and transverse shear stress. 120 mm 50 mm F 40 mm

A hook is fashioned by bending a 8.0 mm wide metal bar into the shape shown. A
force of 85 N is applied at D. The strength of the metal limits both the shear stress
and the bending stress to 70 MPa. Determine the dimension 'a' of the bar such that
the strength is not exceeded. Your solution must demonstrate that the bar is safe for
both bending stress and transverse shear stress.
