2. Three rigid bodies, 2, 3, and 4, are connected by six springs as shown in the figure. The rigid walls are represented by 1 and 5. A horizontal force F3 = 1000N is applied on Body 3 in the direction shown in the figure. Find the displacements of the three bodies and the forces (tensile/

compressive) in the springs. What are the reactions at the walls? Assume the bodies can undergo only translation in the horizontal direction. The spring constants (N/mm) are

/ci = 500, ki = 400, h = 600, kA = 200, ks = 400, fee = 300.
