The book discusses the mechanics of a particle; the mechanics of systems; the principle of virtual work; and d’alembert’s principle. The text also describes oscillation problems; the kinematics, statics, and dynamics of a rigid body; the theory of relative motion; and the integral variational principles of mechanics. Lagrange’s equations for generalized coordinates and the theory of Hamilton are also considered. Physicists, mathematicians, and students taking Physics courses will find the book invaluable.
