Class Assignment Figure 1 shows a two-degree-of-freedom spring-mass model system for a mechanical component consisting of two bodies and three springs connected such that it may be set into tree vertical vibrations. There is no frictional torce between the wheels and the floor. a) Starting from the free-budy-diagram of the system, derive the equation of motion of the system b) Determine the natural frequencies of the system and compare the amplitudes of the movements of m and m2 for each frequency. GIVEN: mı - 70 kg, m2 = 140 kg, K: - 60 kN/m, Ky - 45 kN/m, K3 - 30 kN/m. Let the instantancous displacement of mı and m2 be Xi and x3 respectively. X1 Xz füametis fim in m2 Ting Figure 1
