For the spring assemblage shown in Figure P2-2, determine the displacement at node 2 and the forces

Question:

For the spring assemblage shown in Figure P2-2, determine the displacement at node 2 and the forces in each spring element. Also determine the force F3. Given: Node 3 displaces an amount Î´ = 1 in. in the positive x direction because of the force F3 and k1 = k2 = 1000 lb/in.
