For each of these problems, (a) construct a Mohr's circle of stress. Using this Mohr's circle, (b) determine the principal stresses and show them on a properly oriented stress element, and (c) determine the maximum shear stress and the normal stress on the planes of maximum shear and show these on a sketch of a properly oriented stress element. 0x = 3000 psi, oy = -5000 psi, and Txy = -3000 psi
