For the five-spring assemblage shown in Figure P2–17, determine the displacements at nodes 2 and 3 and the reactions at nodes 1 and 4. Assume the rigid vertical bars at nodes 2 and 3 connecting the springs remain horizontal at all times but are free to slide or displace left or right. There is an applied force at node 3 of 1000 N to the right.

Let k⁽¹⁾ = 500 N/mm, k⁽²⁾ = k⁽³⁾ = 300 N/mm, and k⁽⁴⁾ = k⁽⁵⁾ = 400 N/mm.
