Calculate the critical factor of safety for the Free Body Diagram of a portion of a round solid shaft shown below. The shaft is made from cold drawn AISI 1040 CD steel and is to be subjected to the following factored loads. Constant Torsion (T) = 0.05kN.m, constant Axial Force F =10kN, fluctuating Bending Moment (M) from 0 to 0.075kN.m. The shaft does not rotate and operates at room temperature. Estimate the number of cycles to failure of the shaft. T F M 20mm 2mm M F 15mm T Calculate the critical factor of safety for the Free Body Diagram of a portion of a round solid shaft shown below.
