Mechanical Vibration/Lagrange form Applied

Why Use Lagrange Form? edit

The 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

  1. Determine the equation of motion
  2. Plot the equation of motion

where T equals the kinetic energy of the system
U equals the potential energy in the system.
