LIQUID FILLED GYROSCOPE: THE EFFECT OF REYNOLDS NUMBER ON RESONANCE

Abstract

A gyroscope with frictionless bearings was designed and built. Resonance experiments with oils of various viscosities substantiated the results of the authors previous work, i.e., to account for the observed behavior of the gyroscope at resonance, Stewartson's inviscid theory requires a viscous correction. The experiments also showed that the rate of growth of the nutational amplitude at resonance is strongly influenced by the nature of the boundary layer. At larger amplitudes, non-linear behavior of the oscillating fluid appears to dominate responses of the gyroscope.
