Question details

Task 2: Design a supporting trus element truss model. You need to make the truss s Design a supporting truss for the rescue helicopter, as shw in figure 2(a). Figure 2(b) shows the finite e truss ibars as described ins asi strong and as light as possible and you are given 3, Table-1. The truss is fixed at only two points E and G an FEA LAB2_2.mph. e your model on the m-drive with ,file name 1 ft 1 ft 1 ft 1 ft 2 ft 2 ft 8 in. 8 in ib 0,000 Figure 2 (a) Rescue helicopter and (b) truss finite element model.
