Salimbeni: Opuscoli di geometria e balistica 1780

Leonardo Salimbeni (* 1752 in Spalato , † 1823 in Verona ) was an Italian mathematician and engineer .

Salimbeni studied at the military academy in Verona, where he was a student of Antonio Maria Lorgna , whose successor he became head of the academy, even when it was moved to Modena in 1798 under Napoleon .

He is known for his early contributions to statics, especially the statics of vaults and arches made of masonry, about which he published a book in 1787. Lorenzo Mascheroni and, in France, Philippe de la Hire , Charles Bossut and Charles Augustin de Coulomb were forerunners in this direction . In contrast to his predecessors, after Edoardo Benvenuto he is also interested in the forces during the construction phase of a vault. Salimbene followed a geometrical approach (which he later translated into analytical formulas), but was only partially successful as a forerunner of graphic statics of the 19th century (Benvenuto). According to Jean-Victor Poncelet , his actual new contribution is buried under numerous geometrical evidence (in the style of old authors such as Christiaan Huygens ): Salimbene found the support line of arches of constant finite cross-sectional thickness and found that it no longer corresponded to the chain line of the idealization of infinitely thin arches as many engineers assumed until the 19th century.

In 1788 he published a textbook on statics resulting from his lectures. He also published on ballistics.

Among the eighteenth-century authors, he found only Coulomb and Salimbeni worth investigating.
