Pierre Couplet
Pierre Couplet des Tortreaux (around 1670 - December 23, 1743 ) was a French engineer.
Couplet was the son of the engineer and member of the Académie des Sciences Claude-Antoine Couplet (1642-1722). In 1696, Pierre Couplet himself became a member of the French Académie des Sciences, in which he replaced his father as treasurer in 1717. Soon after entering the academy, he took part in an astronomical expedition to Brazil that lasted two and a half years, and in 1700 in the geodetic longitude measurement of Jacques Cassini . He became professor of mathematics for the pages of the Grande Écurie .
Between 1726 and 1733 he published some treatises on building technology and mechanics in the communications of the French Academy. Among other things, about the earth pressure on retaining walls (De la poussée des terres contre leurs revetements 1726–1730), wind forces, trusses, sleds, carriages and the pulling force of horses. He also dealt with the load bearing capacity of vaults (De la poussée des voutes 1729/31, Seconde partie de l'examen de la poussée des voutes 1730/32), which was later recognized by Jacques Heyman .
