Understanding Arch Construction: Keystone and Voussoir Mechanics #13513 (License: Personal Use)

This hand-drawn schematic illustrates a traditional Roman-style stone arch composed of evenly spaced wedge-shaped voussoirs, converging at the apex where the keystone is positioned. A dashed line traces the path from the keystone downward, emphasizing its pivotal role in transferring compressive forces laterally to the abutments. The rough, inked lines suggest an educational or historical context, highlighting foundational principles of load-bearing masonry.

Used in architecture, civil engineering, and history education materials to explain how arches support weight without mortar; matches user intent for learning structural mechanics or designing heritage-inspired builds.
