While reading about Lagrange equations, I found the following remark about the Jourdain principle (I try a quickndirty translation of the german original, hope it makes sense):
"For big systems with very many degrees of freedom - especially in vehicle dynamics and aerospace - the many derivatives in the Lagrange equations result in a considerable effort. There is general agreement that in this cases the Jourdain Principle should be preferred, which is similar to the d'Alambert principle".
Now I'm not looking for an explanation of the principle, but for a statement like "Yep, it's usefull for doing xyz". So that I know whether I should add it to the list in my brain of the 1 trillion things I have to learn someday...
