2.16. The stress at a point is defined by the components Oxx = MPa, Ozz = 70 MPa, Ory = -80 MPa, ơyz = Ozx =0 MPa, so that o2z is a princi- pal stress. Find the other two principal stresses and sketch the three Mohr's circles. Hence determine the magnitude of the maximum shear stress. 120 MPa, ơyy =300
