Calculate the displacements at nodes 1 and 2, the reactions at nodes 1 and 3, as well as the axial strains and stresses in the three bars of the planar truss shown below. Use analytical (hand) finite element formulation. Known are P₁ - 500 N, P-1000 N. /-0.05 m, the constant cross- sectional area of all bars A = 0.0001 m², Young's modulus E= 2 x 10¹¹ N/m², and Poisson's ration v=0.3.
