Sensitivity of mechatronical systems represented by polar graphs and structural numbers as models of discrete systems

There is formulated and formalized parametrical sensitivity concept of bar mechanical or mechatronical system in representation of pole graphs and structural numbers as a stage of making production's decisions assist in synthesizing continuous longitudinally or torsionally vibrating mechanical or mechatronical system. Such formulation makes possible to study continuous mechanical system sensitivity on transformed plane of complex variable r(=th Γs) or p(=th γs).
