Transcribed Image Text:At a point on the free surface of a stressed body, a normal stress magnitude of Sy = 60 MPa (C) and an unknown positive shear stress
exist on a horizontal plane. One principal stress at the point is 9 MPa (C). The absolute maximum shear stress at the point has a
magnitude of 77 MPa. Determine the unknown stresses on the horizontal and vertical planes and the unknown principal stress at the
point.
