The simply supported beam in Figure Q1 has a rectangular cross section 120 mm wide and 200 mm high. (a) Compute the maximum bending and shear stress in the beam. (b) Sketch the bending and shear stress distribution over the cross section on which the maximum bending and shear stress occurs, respectively. (c) Compute the bending stress at a point on section B that is 25 mm below the top of the beam.
