Question

Test Consider a two-degrees-of-freedom system shown below. ド. PN What is the amplitude of vibration (particular solution only) of mass 2 (at the input frequency)? The answer must be positive. Keep 3 significant figures, and omit units. Use m1 2 kg m2 4 kg k1 147 N/m k2 146 N/m K3 192 N/m F1 # 411 cos(0.50 N Note that the system is not damped. The homogeneous response does not decay to zero. The masses vibrates at three different frequencies two natural frequencies and the input frequency), I am asking for the ampitude of the particular solution only. If I put damping in the problem, the algebra becomes messier but the homogeneous solution will decay to zero. In this case, the steady-state response is same as the particular solution. I would just ask for the steady-state amplitude to mean the amplitude of the particular solution. F2 = 0.
