A new model in nonholonomic mechanics, the Rosen-Edelstein model, has been studied. We prove that the new model is a Lagrange problem in which the action integral ∫t1t0 Ldt can be made stationary. The theoretical basis of nonholonomic mechanics is investigated and discussed. Finally, we give the range of practical applications of the Rosen-Edelstein model.
