===Definition===
The radial distance of the point from z-axis of re-oriented coordinate system along principal moments of the tensor inertia '''I'''.
The radial distance of the point along a selected axis of the superimposed coordinate system of a reference structure. Any axis of the superimposed coordinate system can be selected.
