Abstract

Appareil de mesure d'un effort, notamment de la poussée d'un pack de rugby au cours d'une mêlée. L'appareil comprend un bâti 1 possédant des accessoires de poussee et pouvant se déplacer sur des rails 8 à l'aide de roues 4. Un vérin 3 résiste à l'effort appliqué au bâti et la pression dans le vérin est mesurée par une jauge de pression. Une pompe et une soupape de fuite permettent de faire varier la pression dans le vérin 3.
