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.
