At a point on the free surface of a stressed body, a normal stress magnitude of Sy-74 MPa (T) and an unknown negative shear stress exist on a horizontal plane. One principal stress at the point is 185 MPa (T). The maximum in-plane shear stress at the point has a magnitude of 83 MPa. Determine the unknown stresses on the vertical plane, the unknown principal stress, and the absolute maximum shear stress at the point.
