FIELD: measurement equipment.SUBSTANCE: proposed method involves determination of angular rotation speed of a spinner and angular precession speed of the spinner in straight and reverse positions of the spinner. A disk with through holes in the form of a segment, which is put on an axis, is used as a spinner. Angular rotation speed of the spinner is determined as per the number of intersections of light flux with the disk segments per unit of time. Angular precession speed of the spinner is determined as per the number of intersections of light flux with the spinner axis. Gravity acceleration is calculated by formulawhere ?- angular rotation speed of the spinner and ?- angular precession speed of the spinner in straight position, and ?- angular rotation speed of the spinner and ?- angular precession speed of the spinner in reverse position, L - spinner axis length, R - disk radius.EFFECT: improving determination accuracy of gravity acceleration.2 cl, 2 dwg |
