A steel beam, of lengths a=4 m and b=4 m and a hollow box cross section, is supported by a hinge support A and roller support B, see Figure Q.1. The width and
height of the cross section are 200 mm and 300 mm, respectively, and the wall thickness of the cross section is 5 mm. The beam is under a distributed load of the
intensity that linearly varies from q = 0 kN/m to q=4.4 kN/m for AB span; and is constant with q= 4.4 kN/m for BC span. The Young's modulus of steel is 200 GPa.
