Question:
Four rigid bodies, 1, 2, 3, and 4, are connected by four springs as shown in the figure. Bodies 2 and 4 are fixed. Assume the bodies can undergo only translation in the horizontal direction. The spring constants ( \(\mathrm{N} / \mathrm{mm})\) are: \(k_{1}=400, k_{2}=500, k_{3}=500\), and \(k_{4}=300\). Assume the mass of bodies 1 and 3 as \(m_{1}=10 \mathrm{~kg}, m_{3}=30 \mathrm{~kg}\). Calculate the natural frequencies and corresponding mode shapes.
