DYNAMICS OF LIQUID FILLED SHELL: RESONANCE IN MODIFIED CYLINDRICAL CAVITIES

Abstract

A search was made, using a liquid-filled gyroscope, for resonance frequencies in modified cylindrical cavities. The fill-ratio at which the resonant frequency occurs shows considerable sensitivity to cylindrical modifications. Simple rules are given for predicting, approximately, the change in this fill-ratio as a function of the modifications. In the Appendix, Wedemeyer suggests a better way of prediction. Tests of a cylindrical cavity with a central rod show that the air gap between the column and the free surface of the disturbed fluid should not, at small yaws, be less than 1/16 inch for non-interference with resonant conditions.
