The known stress components at a point in a body, relative to the (x, y, z) axes, are ox = 20MPA, Oy = 10 MPa, txy= 30 MPa, txz = -10 MPa, and tyz = 80 MPa. Also, the second stress invariant is I2 = -7800 MPa. (a) Determine the stress component o,. Then determine the stress invariants I, and I3, and the three principal stresses. (b) Show that I1, I2, and I3, are the same relative to (x, y, z) axes and relative to principal axes (1,2,3).
