Realization of Nonholonomic Constraints and Singular Perturbation Theory for Plane Dumbbells
Sergiy Koshkin, Vojin Jovanovic
We study the dynamics of pairs of connected masses in the plane, when nonholonomic (knife-edge) constraints are realized by forces of viscous friction, in particular its relation t…
