A timber beam of thickness 100 mm and depth 300 mm protrudes 2.0 m from a wall in which it is fxed. What is the maximum load that can be applied to the free end if the maximum allowable stress is 7 MPa?

A beam has to support loading which results in a maximum bending moment of 25 kN m. If the maximum permissible bending stress is 7 MPa, what will the required section modulus be?
