| Funktion |
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. |
