Semicircular Brick Arch Diagram - Construction & Structural Design #1819492 (License: Personal Use)

This hand-drawn diagram illustrates a classic Roman-style semicircular arch composed of wedge-shaped bricks (voussoirs) arranged radially around a central axis, with a keystone at the apex. The irregular ink lines suggest a historical or educational sketch, emphasizing structural integrity through compression forces. Such arches were foundational in ancient and medieval architecture for spanning openings without internal supports.
