The prismatic bar in the figure is subjected to an axial compressive load P = -70 kips. The cross- sectional area of the bar is 2.0 in. Determine the normal stress and the shear stress on the n face and on the t face of an element oriented at angle 0 = 45. Use free-body diagrams and equilibrium equations to solve for the required stresses. P t n P The prismatic bar in the figure is subjected to an axial compressive load P = -70 kips.
