To start out the investigation from the mass–spring–damper think the damping is negligible and that there's no external power placed on the mass (i.e. absolutely free vibration). The pressure placed on the mass with the spring is proportional towards the amount the spring is stretched "x" (assuming the spring is https://collinauoga.daneblogger.com/28284690/the-ultimate-guide-to-isolating-vibration
