Abstract
It is the purpose of this paper to discuss fundamental concepts involved in mechanical impedance and mobility. The equations used in the formulation of the concepts are examined for meaning and content. It is demonstrated for any prescribed structure that every possible observed mobility element is independent of the number and location of the other measurement points, and every possible observed mechanical impedance element is not. The effects upon the mobility and impedance arrays are discussed for simple expansions and contractions of the tensor. Numerical examples are used to illustrate some of these points.Keywords
