Around steel bar having sy = 800 mpa is subjected to loads producing calculated stresses of p∕a = 70 mpa, tc∕j = 200 mpa, mc∕i = 300 mpa, and 4v∕3a = 170 mpa. (a) sketch mohr circles showing the relative locations of maximum normal stress and maximum shear stress. (b) determine the safety factor with respect to initial yielding according to the maximum-shear stress theory and according to the maximum-distortion-energy theory.
