Kinematyczna równoważność układów sił

Stefan Piechnik
In the paper the definition of kinematic equivalence of a system has been formulated. From the set of forces in which the relation of statical equivalence is given, one can distinguish the equivalence class of forces giving the same kinematic effects. In contrary to static equivalence, the kinematical one depends on the shape of the loaded body. Several examples are presented in which the introduced definition is used in the analysis of slender bars.
