Yes, a mistake that is made over and over again.
There was some ado some time ago about some students who had put a
gyroscope on a precision 'balance'.
They noticed a change of weight that depended on the sense of rotation.
Apparently the bearings are smoother in the direction in which they are
normally run, producing less vibration to rectify, Jan

nonsense, the center of mass is moving along the axis of rotation, which is a fact. See a doctor.
