HW) The load on a beam with square section consists of a bending stress of 20 MPa,an axial stress of 10 MPa together with a transverse shear stress of 5 MPa. Find the factor of safety (N) of the beam made from steel (Yield strength =365 MPa, and ultimate strength=636 MPa) according to 1. Maximum principal stress theory; 2. Maximum shear stress theory; 3. Maximum principal strain theory; 4. Maximum strain energy theory; and 5. Maximum distortion energy theory.
