The figure (not to scale) shows a 2D truss comprising 4 members. The members are to be treated as linear bar elements, of cross-section area A and with Young's modulus E. A force p acts at node E. The other 4 nodes are pin-jointed to the ground. Given Young's modulus E=110GPa and cross section area A=200 mm2, the force coordinates Pp−5kN and Pp−9kN, the heights H1−1.6 m and H2−1.3 m, the angles θA−40,θB−70, θC−60 and θD−85∘, calculate the coordinates of the displacement at node Ez8 and yy in mm, and the stress in each bar σ1,σ2,σ1 and σ2 in MPa. Enter your answers in the boxes below. The answers are acceptable within a tolerance of 0.1 mm for the displacements and 1MPa for the stresses. σI:σE:σt: MPa (2 marks) σ2: MPa (2 marks) σs: MPa (2 marks) σt: MPa (2 marks) mm(2 marks) mm(2 marks )
