(Q4) The truss shown in Figure 4 has a typical construction where all the truss connections are pinned connections (i.e., each member is cut to length and members are pinned at each end). The supports at node A are pin supports and at node E are roller supports. All truss members are made of 125 SHS 5 steel. Self-weight can be ignored. For this configuration and loads shown: (a) (b) 5m Use SPACE GASS to determine all reactions and member forces in the truss. Include graphical outputs from SPACE GASS showing the member numbers and member forces. Also include a printout of input data and output results. (4 marks) Use hand calculations to check the reactions and determine the member forces in all members. (include in your answers whether the members are in tension or compression).
