Radial kinetic nonholonomic trajectories are Riemannian geodesics!
arXiv:2010.12444
Abstract
Nonholonomic mechanics describes the motion of systems constrained by nonintegrable constraints. One of its most remarkable properties is that the derivation of the nonholonomic equations is not variational in nature. {However, in} this paper, we prove (Theorem 1.1) that for kinetic nonholonomic {systems}, the solutions starting from a fixed point are true geodesics for a family of Riemannian metrics on the image submanifold of the nonholonomic exponential map. This implies a surprising result: the kinetic nonholonomic trajectories with starting point , for sufficiently small times, minimize length in !
