EFFECTS OF EXTERNAL FORCES ON VIBRATING CRYSTAL PLATES

Abstract

Frequency deviation data obtained by the application of compressional stress to a vibrating circular AT piezoid have been extended in the resonant frequency domain. Special efforts have been made to carry out experiments in the region near the X axis, which is ordinarily obscured by the excitation mechanism. It is hoped to establish both experimentally and theoretically the absence of discontinuities in the deviation function and its derivatives at this rather natural boundary. The crystal is found especially sensitive to compressional stress in that angular locality, but otherwise the frequency deviation remains fairly constant in observations made thus far. (Author)
