Problem of finite element analysis(urgent)

Submitted by Himanshu Dhadwal on

Consider the truss system shown in Fig. 2 modelled by three elements. The element numbers are shown in brackets. The node numbers are as indicated in the figure. Suppose that all the trusses have a cross sectional area of A = 0.1 m2 and Young’s modulus E = 70 GPa. Determine the displacements at all the nodes if the force P = 2000 N. The length L = 2 m.truss.jpg
