October 5, 2012 by Multimedia Publications and Printing Services

Lecturer: M. Fabbrichesi , SISSA

In this lesson the professor make an extension of Hamilton's principle to non-conservative and non-holonomic systems introducing the method of Lagrange undetermined multiplier. He solves three examples using this technique, the problem of a hoop rolling down an inclined plane, one with 4 degree of freedom of a disc that can move in a plane and can rotate around the principal axis and around the center of mass and a more complicated one with 6 degree of freedom, the two-body problem with central forces , the motion of the Sun and the Earth.
