# Question: The principal stresses

Consider a three-dimensional state of stress characterized by:

σxx = 3,000 σyy = 2,000 τxy = 0.

σzz = 4,000 τzx = 0. τyz = 2,500

where units are psi and compression is positive. Find: the magnitude and direction of the principal stresses and illustrate with a sketch
