3. Consider an undamped SDOF system subjected to harmonic forces. An optimal TMD with damping is to be used to reduce system vibrations. Determine the minimum mass ratio of the TMD so that the maximum displacement amplitude of the structure does not exceed 5 times its static deflection. What are the optimum tuning frequency and the optimum damping ratio of the TMD?
