The Figure Not To Scale Shows A 2d Truss Comprising 4 Members The Members Are To Be Treated As Linear Bar Elements O 1 (37.77 KiB) Viewed 39 times

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 )
