The INSTRUMENT is made up of a base onto which the bearing holders and drive motor are mounted, and bearings that can be put into holders to meet the end requirements for test shafts, namely both end fixed and one end free, one end fixed. The driving motor was controlled by a variac. The device illustrates the phenomenon of several shafts rotating around a single rotor. The unit simply illustrates the principle because the test is destructive and cannot be utilised afterward.

In contrast to those with bare shafts, the results are, nonetheless, closer to theory. Additionally, it can be shown that the shaft resumes running true after reaching spinning speed.
