Summary

[edit]
Description
Deutsch: Labormodell eines Wägeprinzips mit Parallelogrammführung und Federwaage. Es ist eine abgewandelte Roberval-Waage, bei der die rechte Seite der Roberval-Waage durch eine Feder ersetzt wurde. An der Länge der Feder kann man die Kraft ablesen und damit das Gewicht auf dem Wiegefläche errechnen. Man würde durch Auflegen von bekannten Gewichten eine Skale erstellen. Ein ähnliches Prinzip wurde bei Briefwaagen verwendet.
  • Drehpunkt links oben - Betrachtung der Zugkraft auf das Lager des oberen Querlenkers
  • Drehpunkt links unten - Betrachtung der Druckkraft auf das Lager des unteren Querlenkers
  • Drehpunkt rechts oben - Betrachtung der Zugkraft auf das Lager der senkrechten Stange
  • Drehpunkt rechts unten - Betrachtung der Druckkraft auf das Lager der senkrechten Stange
English: Mock-up model of a weighing principle with parallelogram guiding and spring scale. It's a modified Roberval balance, where the right side is replaced by a spring. The length of the spring is equal to the drag. Then the weigh on the scale tray could be calculated. There would be a calibrated scale reading on the spring scale. A similar Principle was used for letter scales.
