A beam bridge structure as shown in Figure 2 is supporting the bridge beam. The supporting vertical beams are equally distanced along the bridge length L. Given that the middle vertical beam is made from structural steel A36 with area of K00 mm² (K is the largest digit in your matric number) while the two outer vertical beams are made from copper alloy C83400 with area of L00 mm² (L is the 2nd largest digit in your matric number). L Figure 2 a) Explain what are all the considerations needed to estimate the weight of the beam that can be supported by the three vertical beams. b) Justify your explanations with the calculations to obtain the maximum beam weight that can be supported by the vertical beams. c) Given the three materials below with similar area (K00 mm2), select one material which you think suitable to replace the middle vertical beam from structural steel to get the most weight can be supported. Justify your answer with supporting calculations.
