A ductile hot-rolled steel bar has a minimum yield strength in tension and compression of 50 kpsi. Using the distortion-energy and maximum-shear-stress theories determine the factors of safety for the following plane stress states: (a) a = 12 kpsi, o, = 6 kpsi (b) a = 12 kpsi, Txy = -8 kpsi (c) a = -6 kpsi, o, = -10 kpsi, Ty = -5 kpsi
