Question

Using the Pole Method determine the stresses acting on the horizontal and vertical planes for the following: Plane A Normal stress 50 psi compression and Shear Stress 150 psi counter clock wise rotation Plane B Normal stress 250 psi compression and Shear Stress 50 psi clockwise rotation Plane B is oriented 10 degrees counter clockwise from horizontal
