To start out the investigation on the mass–spring–damper believe the damping is negligible and that there is no external pressure applied to the mass (i.e. free vibration). The force applied to the mass from the spring is proportional to your amount the spring is stretched "x" (assuming the spring is https://vibration-isolator-design92692.blogspothub.com/28233006/the-ultimate-guide-to-isolating-vibration
