Equations of Motion using Euler-Lagrange Formalism for Small Vertical Motions

[pedromcrosa]

(sorry for my english :P)

Hi,

I need help with this problem:

.The question is:

Write the equations of motion using the Euler-Lagrange formalism, assuming small motions around the vertical position.
clue:determine the work of the forces as a function of degrees of freedom.

You need to make an attempt to solve the problem, but in general,
1. write down your generalized coordinates i.e. identify and use your constraints.
2. write the potential and kinetic energies of the system
3. find L = T-V, where T =kinetic and V = potential and L = lagrangian
4. Write the Euler equations

Thanks for the help Dikmikkel,

i'm going to try to do .
