Objective:
The objective of this project was to design a spring-damper connection for a
vibration sensor with an internal mass m. The machine vibrates at a specified frequency
w and will be monitored by the sensor. The mai

This project involved a spring-damper connection shown below in figure 1. Given
different choices for spring stiffness and damping, the objective was to choose a combination
