Find the displacements of the rigid bodies shown in figure 1.1. Assume that the only nonzero force is \(F_{3}=1000 \mathrm{~N}\). Determine the element 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 \((\mathrm{N} / \mathrm{mm})\) are \(k^{(1)}=500, k^{(2)}=\) \(400, k^{(3)}=600, k^{(4)}=200, k^{(5)}=400\), and \(k^{(6)}=300\).
