A ductile hot-rolled steel bar has a minimum yield strength in tension and compression of 350 MPa. Using the distortion-energy and maximum-shear-stress theories determine the factors of safety for the following plane stress states: (a) σx = 100 MPa, σy = 50 MPa (b) σx = 100 MPa, τxy = - 75 MPa (c) σx = - 50 MPa, σy = - 75 MPa, τxy = - 50 MPa (d) σx = 100 MPa, σy = 20 MPa, τxy = - 20 MPa
