The figure shows a section of a shaft made of annealed steel with yield strength of 600 MPa and ultimate tensile strength of 700 MPa. Diameters of the shaft are D=30 mm and d=20 mm. Fillet radius of the shoulder section is 2.5 mm. The shaft is rotating and subjected to steady bending moment of M=51 Nm, steady torsion of T=58 Nm and steady axial load of F=14 kN. The operating temperature of the shaft is 20 ᵒC and reliability is 99%. The shaft has ground surface. Calculate the alternating component of the normal stress (in MPa). (If there is no alternating component of the normal stress, enter "0" in the answer box)
