3.34: The spring-mass-damping machine is under a harmonic force. The amplitude was found to be 20 mm at resonance and 10 mm at 0.75 times the resonance frequency. Find the damping ratio of this system
Amplitude X Given, X = 20mm at resonant frequency X = 10mm at 0.75 resonant frequency Now substituting the values in the above formula the calculations are as follows:
