A rectangular hollow section, orientated such that it is in bending about its major axis of bending, is used to span 5m. It is simply supported at both ends. The external dimensions of the section are 100mm (wide) by 250mm (deep). The wall thickness is 8mm.

If the maximum allowable bending and shear stresses are 140MPa and 30MPa, respectively, determine the maximum allowable distributed load that the beam section

can support.
