Applications,fferent nature. When it was first developed in 1965 its authors had in mind an application to spacecraft. Some details of the mathematics in this case and a typical result will be shown after this introduction. Another filed for applications is found in the study of mechanisms. One aspect will be de

María del Carmen Alanís Figueroalysts will differ in their preference for various ways of formulating equations, one man choosing Lagrange’s equations, a second preferring Hamilton’s principle, and a third relying upon a Newton-Euler formulation, these differences are much less fundamental than the initial choice of a mathematical model of the vehicle.

María del Carmen Alanís Figueroady was rigid, but this is a very special case. The procedure to be followed in developing equations for systems of substructures depends very much on the substructure models. Various approaches will be outlined here without detailed development.
