De Beghinselen der Weeghconst (The Principles of Statics, lit. The Principles of the Art of Weighing) is a landmark book written in the Dutch language by Simon Stevin in the 16th century.
Importance[]
De Beghinselen of Weeghconst is a book about statics, written by Flemish physicist Simon Stevin. It was published in 1586, in a single volume with De Weeghdaet (The Act of Weighing), De Beghinselen des Waterwichts (Principles of Hydrostatics), and an Anhang (an appendix).[1] In 1605 there was another edition.
The importance of the book was summarized by the Encyclopædia Britannica:[2]
In De Beghinselen der Weeghconst (1586; “Statics and Hydrostatics”) Stevin published the theorem of the triangle of forces. The knowledge of this triangle of forces, equivalent to the parallelogram diagram of forces, gave a new impetus to the study of statics, which had previously been founded on the theory of the lever. He also discovered that the downward pressure of a liquid is independent of the shape of its vessel and depends only on its height and base.
