At a point on the free surface of a stressed body, the normal stresses are 16 ksi (T) on a vertical plane and 40 ksi (C) on a horizontal plane. An unknown negative shear stress exists on the vertical plane. The absolute maximum shear stress at the point has a magnitude of 33 ksi. Determine the principal stresses and the shear stress on the vertical plane at the point.
