Question:
The two-element truss in figure is subjected to external loading as shown. Using the same node and element numbering as in figure, determine the displacement components of node 3, the reaction force components at nodes 1 and 2, and the element displacements, stresses, and forces. The elements have modulus of elasticity E1 = E2 = 10 × 106 lb/in.2 and cross-sectional areas A1 = A2 = 1.5 in.2 . (30 points)
