Study of Mechanical ComponentsLeonardo da Vinci

741
This folio (c. 1500) shows axles, wheel assemblies, and articulated joints arranged in precise mechanical studies. The configurations relate to experiments in vehicle or artillery motion and the stresses carried through rotating parts. Their clarity shows Leonardo’s analysis of friction and mechanical advantage, ideas that informed later engineering practice.
