Abstract
Il s'agit par exemple du contrôle de la flexion latérale dont est l'objet le bras de volée BII d'une flèche de manutention articulée 10 à raison de l'obliquité vis-à-vis de celui-ci de la charge à laquelle cette flèche est attelée Suivant l'invention, le pivot B par lequel le bras de volée BII est articulé au bras de relevage BI correspondant forme un capteur de force porteur de jauges de contrainte, qui sont disposées de manière à n'être sensibles qu'aux seuls efforts tranchants, et qui sont montées en pont de Wheastone de manière appropriée Application aux engins à flèche de manutention articulée.
