A 1 1/4-in.-diameter hot-rolled steel bar has a 1/8-in.-diameter through hole drilled in the cross direction. The bar is non-rotating and is subjected to a bending moment fully reversible M = 1600 lbf in. in the same plane as the axis of the cross hole. The material has an average tensile strength of 58 kpsi. Estimate reliability. The size factor should be based on gross size. Indicate which table you used (from which book) to obtain Kt.
