Roman Arch Construction Diagram - Engineering Principles Explained #2099111 (License: Personal Use)

This hand-drawn diagram depicts a semicircular Roman arch composed of wedge-shaped stones (voussoirs), with two dashed lines representing the thrust lines converging at the keystone. The illustration highlights how compressive forces travel along the arch’s curve to the abutments, minimizing lateral stress. It serves as an educational tool for understanding classical masonry mechanics.
