Abstract

Dynamomètre dans lequel l'amplitude d'une force, par exemple le poids d'une charge, est déterminée par l'effort engendré dans un barreau de flexion auquel la charge est appliquée. Il comporte un système à levier permettant l'utilisation d'un barreau relativement épais. Il en resulte une grande précision des mesures et la possibilité de les répéter, même lorsque la capacité du dynamomètre est relativement faible. Domaine d'application : mesure de forces.
