# Mechanical Vibration/Lagrange form Applied

## Why Use Lagrange Form?

editThe largest benefit of using the Lagrange form is the deriving the equation of motion is easier for complex systems.

To start out we will start out applying the Lagrange formulation on a spring and mass system defined within the givens. We will

- Determine the equation of motion
- Plot the equation of motion
