The D Alembert Lagrange Principle: Geometrical Aspect
(389K, pdf)

ABSTRACT.  The d Alembert Lagrange Principle and the theory of ideal constraints are the central 
topic in the theoretical mechanics. We consider the theory of ideal constraints and the d Alembert 
Lagrange Principle from the modern differential geometry and tensor analysis point of view. This 
article is pure methodological.
