The stress state in a cube whose edges are parallel to the coordinate axes of an x-y-z system is constant and given by
?11 0 0
0 ?22 0
0 0 ?33
Consider the (010) and (111) planes and find for each
(a) The magnitude of the traction vector acting on the planes.
(b) The magnitude of the normal traction acting on the planes.
(c) The magnitude and direction of the shear traction acting on the planes.
Comment on the tractions on the (010) face of the plane if ?22 = 0.
