Calculate the value of the maximum bending moment in the beam. Enter your answer in kNm to three decimal places. Note: when deriving internal moment equations, use the following orientation of x coordinate:   Segment AB: x changes from 0 at support A to a at support B. After making the cut, keep the part of the beam left from the cut. Segment BC:  x changes from a at support B to L at point C, where L = a + b. After making the cut, keep the part of the beam right from the cut, i.e. distance from point C to the cut is equal L-x.

Question

Calculate the value of the maximum bending moment in the beam. Enter your answer in kNm to three decimal places.

Note: when deriving internal moment equations, use the following orientation of x coordinate:

 

  • Segment ABx changes from 0 at support A to a at support B. After making the cut, keep the part of the beam left from the cut.
  • Segment BC:  x changes from a at support B to L at point C, where L = a + b. After making the cut, keep the part of the beam right from the cut, i.e. distance from point C to the cut is equal L-x.
A steel beam, of lengths a=5 m and b=5 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=5 kN/m for AB span; and is constant with q= 5 kN/m
for BC span. The Young's modulus of steel is 200 GPa.
