For the truss shown below, F1 = 20 kN and F2 = 30 kN. a) Determine the vertical displacement of joint C. Each memeber has a cross-sectional area of A = 300 mmand E= 200 GPa. b) Determine the deformed shape of the truss. F1 F2 3 m 3 m LLLL B с 4 m D Hints: • Option 1: Determine the horizontal reactions first. The vertical reaction at E can be determined hrough equilibrium equations at joint E. • Option 2: All axial forces can be determined through joints C, B and D, without a need of determining any reaction forces. When working on joint D, rotate the x-yaxes to avoid solving simultaneous equations.
