Talk:Energy principles in structural mechanics

Müller-Breslau principle
I really don't know much about the derivation of this principle. When used to find influence lines, it doesn't really feel like an energy method. I guess it comes from virtual work? Should it be noted if it does come from virtual work? Should it be moved to applications? Notthe9 14:41, 1 December 2007 (UTC)
