And do g) the value of the deflection at point C. ALL ANSWERS IN 3 DECIMAL PLACES
Transcribed Image Text:A steel beam, of lengths a=6 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= 4.3 kN/m for AB span; and is constant with q= 4.3 kN/m for BC span. The Young's modulus of steel is 200
