De Beghinselen der Weeghconst ("The Principles of the Art of Weighing") is a book about statics written by the Flemish physicist Simon Stevin in Dutch. It was published in 1586 in a single volume with De Weeghdaet ("The Act of Weighing"), De Beghinselen des Waterwichts ("The Principles of Hydrostatics") and an Anhang (an appendix).[1] In 1605, there was another edition.
