Using Mohr’s circle, solve

The states of stress at two points in a loaded body are represented

in Figs. P1.15 and P1.16. Calculate for each point the normal and shearing

stresses acting on the indicated inclined plane. As is done in the

derivations given in Section 1.9, use an approach based on the equilibrium

equations applied to the wedge-shaped element shown.
