Question: The stresses on two mutually perpendicular planes through a point in a body are 80 MPa and 50 Mpa both tensile. Determine the maximum value

The stresses on two mutually perpendicular planes through a point in a body are 80 MPa and 50 Mpa both tensile. Determine the maximum value of the shear stress which can be applied so that the maximum value of the permissible stress is limited to 120 Mpa. What will be the inclination of the principal stress and the magnitude of the maximum shear stress?
