GAUSS PRINCIPLE FOR SYSTEMS WITH IMPERFECT CONSTRAINTS IN THE CASE OF POSSIBLE DISPLACEMENTS THAT SATISFY THE EXTENDED METHOD OF COMBINING CONSTRAINTS

Let us consider the question of the applicability of the Gauss principle for systems with imperfect constraints (constraints with friction) in the case of possible displacements. A mechanical system of material points () with masses, the position of which relative to the inertial Cartesian coordinate system is determined by the radius vectors (). The system is under the action of given forces and is constrained by joint and independent connections, among which there are both geometri
