Question

The known stress components at a point in a body, relative to the (x, y, z) axes, are our = 20 mpa, ow= 10 mpa, orv = 30 mpa, ox = -10 mpa, and oyz = 80 mpa. Also, the second stress invariant is 12 = -7800 (mpa)2 (a) determine the stress component ozz. Then determine the stress invariants /, and iz and the three principal stresses. (b) show that i, 12, and 13 are the same relative to (x, y, z) axes and relative to principal axes (1, 2, 3).

Answer 1

just do it when values and question is clear but question is not clear ask questions again don't worry if values are clear it can be done
