Hi,
In my course in analytical mechanics, it is said that for a system of n particles subjected to r constraint equations, it is necessary to impose regularity conditions on the constraint surface defined by G = 0 where G is a function of the position of the position of the particles and time, the condition is that the gradient of G is non-zero on the surface G = 0.
I don't understand why we're asking this?
Thanks for your help (and sorry if i made mistakes)
