COULOMB, Charles Augustin de (1736-1806). "Essai sur une application des rgles de Maximis & Minimis quelques Problmes de Statique, relatifs l'Architecture." In: Mmoires de mathmatique et de physique, Anne 1773, pp. 343-382. Paris: Imprimerie Royale, 1776.
4o (252 x 183 mm). 18 folding engraved plates (2 illustrating Coulomb's essay). Contemporary French mottled calf gilt (minor wear to extremities).
FIRST PRINTING OF COULOMB'S FIRST AND MOST IMPORTANT MEMOIR ON MECHANICS which provided engineers with an advanced working theory for determining the strength of materials. In this essay he introduced three propositions relating to equilibrium and resolution of forces, considered friction and cohesion, and gave virtually a theory of the flexure of beams and rupture and shear of brittle materials. Coulomb also determined for the first time the neutral surface of a beam. He was ahead of his time in using the calculus of variations to approach the fundamental problems of structural mechanics. This important memoir provided engineers with an advanced working theory for determining the strength of materials. Singer Technology IV, pp. 479-80; Norman 525.
