A linear spring-mass oscillator has a viscous damping factor ζ = 0.2 and an undamped natural frequency Fn = 6Hz. By referring to Fig 8/11 estimate the range of frequencies ƒ of the periodic applied force for which the amplitude of the oscillator will not exceed twice the static deflection which would be caused by applying a static force equal in magnitude to that of the periodic force. Check your estimate by applying Eq. 8/23
Fig. 8/11.
