The stresses shown act at a point on the free surface of a stressed body. Normal and shear stress magnitudes acting on horizontal and vertical planes at the point are Sx = 80 MPa, Sy = 40 MPa, and Sxy = 75 MPa. Assume β=51∘. Determine the normal stresses σn and σt and the shear stress τn⁢t at this point if they act on the rotated stress element shown.
