TL;DR: In this article, the main parts of the experimental setup currently in development are presented, as well as the general configuration and the main configuration of the test setup, for the Watt balance project.

TL;DR: A preliminary analysis for designing a force comparator to be used in the French watt balance experiment is presented and theoretical calculation results based on realistic assumptions of the static and dynamic behaviors of the balance are presented.

TL;DR: In the French watt balance experiment, a double gimbals with flexure pivots was made out of copper-beryllium alloy as discussed by the authors, which allowed the articulation of the suspension devices of the mass (generating the weight) and coil (on which the electromagnetic force acts) around four coplanar axes which intersect at one point.

TL;DR: The balance du watt as mentioned in this paper is the SI definition of the kilogramme, which is the seule unite de base du Systeme International d'unites (SI) encore definie par un artefact materiel.

TL;DR: In this paper, an exemple d'une telle etude is presented, which permits l'articulation des suspensions de la masse and de la bobine engendrant the force electromagnetique selon quatre axes coplanaires which se coupent en un seul point.
