At a point on the free surface of a stressed body, a normal stress magnitude of S, = 51 MPa (C) and an unknown positive shear stress exist on a horizontal plane. One principal stress at the point is 11 MPa (C). The absolute maximum shear stress at the point has a magnitude of 64 MPa. Determine the unknown stresses on the horizontal and vertical planes and the unknown principal stress at the point. Sgy S Answers: O, = i MPa i MPa Txy = MPa Op2 =
