A multi‐body system with several degrees of freedom and friction‐affected constraints (guidances and journal bearings) is considered. It is supposed that the original system and all systems, which must be considered as result of sticking coordinates, are kineto‐statically determinate structures. It is also assumed that the relative velocities in the constraints depend respectively on one of the generalized coordinates and its derivative. A criterion is presented, which establishes the state of the system, when relative movements in some constraints with friction stop simultaneously. As an example a system with four degrees of freedom and seven friction‐affected constraints is considered.
