To start out the investigation on the mass–spring–damper suppose the damping is negligible and that there is no exterior pressure applied to the mass (i.e. free vibration). The power placed on the mass because of the spring is proportional on the amount the spring is stretched "x" (assuming the spring https://whatisavibrationisolatora92457.therainblog.com/28048223/details-fiction-and-vibration-isolator-hanger
