Structure of mechanism

Function This scale comprises a horizontal beam holding two brass pans. A needle attached to the beam, pointing upwards, indicates when the device is balanced. The beam rests, via a knife-edge (a steel prism) attached to the beam, on a metal base. The whole mechanism is balanced thanks to a second beam (not visible here) located inside the base.
 

Application

Examples of application This instrument is used to weigh objects. It was used by future teachers during their studies at the men’s and women’s teacher training colleges, now the IUFM (University Teacher Training Institute) in Clermont-Ferrand.
