Equilibrium with Lagrangians

  1. Nov 26, 2012 #1
    So let's say we have a mechanical system described by some Lagrangian [itex]L=L(q_i,\dot{q}_i)[/itex], where the qi's are the generalized coordinates of the system. Does the condition
    [tex]\frac{\partial L}{\partial q_i}=0[/tex]
    give the equilibrium configurations of the system? Intuitively it seems so, but I can't prove it.

    What is the condition for equilibrium in newtonian mechanics?

    [tex]\frac{\partial V}{\partial x}=0./tex]. I'm having trouble connecting this to Lagrangians though....
