STABILITY OF STATIONARY MOTION OF MECHANICAL SYSTEMS IN A RESISTIVE MEDIUM.

The problem of the stability of stationary motion of holonomic mechanical systems with cyclic coordinates is often solved by the Chetaev method which consists of constructing a positive-definite first integral in the form of a combination of the energy integral and integrals corresponding to the cyclic coordinates. It is shown that this method can be applied to the stationary motion of mechanical systems with quasicyclical coordinates when the generalized forces consist of potential and dissipative components.
