On the instability of equilibrium of a mechanical system with nonconservative forces

Autor: Vesković Miroslav, Čović Vukman

Publikováno v: Theoretical and Applied Mechanics, Vol 31, Iss 3-4, Pp 411-424 (2004)

In this paper the stability of equilibrium of nonholonomic systems, on which dissipative and nonconservative positional forces act, is considered. We have proved the theorems on the instability of equilibrium under the assumptions that: the kinetic e
