Query: Lagrange-d'Alembert-Poincar\`e equations by several stages   The aim of this paper is to write explicit expression in terms of a given
principal connection of the Lagrange-d'Alembert-Poincar\`{e} equations in
several stages. This is obtained by using a reduced Lagrange-d'Alembert's
Principle in several stages, extending methods introduced for the case of two
stages by one of the authors and collaborators. The case of the Euler's disk is
described as an illustrative example.
