Three rigid bodies, 2, 3, and 4, are connected by four springs as shown in the figure. A horizontal force of \(1,000 \mathrm{~N}\) is applied on body 4 as shown in the figure. Find the displacements of the three bodies and the forces (tensile/compressive) in the springs. What is the reaction at the wall? Assume the bodies can undergo only translation in the horizontal direction. The spring constants (N/mm) are: \(k^{(1)}=400, k^{(2)}=500, k^{(3)}=400, k^{(4)}=200\).
