The state of stress at a point is x = 2, y = 6, z = 4,

The state of stress at a point is σx = −2, σy = 6, σz = −4, τx y = 3, τyz = 2, and τz x = −5 kpsi. Determine the principal stresses, draw a complete Mohr’s three-circle diagram, labeling all points of interest, and report the maximum shear stress for this case.
