Semicircular Brick Arch Diagram - Architectural Construction Guide #1883047 (License: Personal Use)

This black-and-white line drawing depicts a classic Roman-style semicircular arch built from uniformly shaped voussoir bricks, converging at the apex without a distinct keystone. The rough, hand-drawn texture suggests an educational or historical illustration, emphasizing construction principles over realism. It illustrates how compressive forces are transferred laterally through the curved form to the abutments.

Used in architecture education, masonry tutorials, historic preservation resources, and civil engineering references; targets students, builders, and heritage restorers seeking foundational knowledge of arch mechanics.
