| Abstract: | Lagrange-d′alembert equation is a unified and unified one in dynamics which reveals its general laws and serves as both a general method for solving dynamics problems and a base for analytical mechanics. A further research in this respect is of great value from both the the-oretical and practical points of view.This paper deals with its general meaning,points out theconditions that limit its applications.By deducing,three general laws of mechanics and the law ofconservation of mechanical energy have been put forward.the limitations of the equation andthe problems not so easy solve have also been studied. |
