A means for simultaneous determination of the radial and angular vectors of rotary motion of a body relative to a single reference axis, by measurement of the common aid differential states of three position detectors and, together with an axial position detector, thus to allow the measurable modulation of magnetic devices such as to provide measurable vector forces to support that body against the vector effects of any external forces that tend to change its position relative to the reference axis, in the absence of any contact between the rotor and the combined system of sensors and magnetic devices. Measurement of the vector forces applied to the suspended b>dC and its resultant vector displacements, provides the functional basis of a device suitable for measuring the effects of mechanical interaction between that body and any spatially constrained sample material in contact with the b>dC, with respect to the applied vector stresses and resultant vector strains that exist as a result of any shearing or grinding abrasion or indentation deformation or cutting action applied by the rotor to that material during a measured time period. The basic device being consistent with the functions of a rotary viscometer or rheometer or appropriate for use in evaluating the action of a drilling or milling cutter, even when the sample material and the b>dC are confined within a chamber subjected to low or high internal pressure with respect to the external environment. Such confinement also avoids volatile loss of constituents from the sample material and any environmental hazard arising from such loss. |
