Question:medium

Arches and shells use primarily which type of strength in their design?

Show Hint

Structural Geometry Advantage: - Beams span spaces by bending (creating heavy internal tension and compression). - Arches and Shells span spaces by squeezing together (pure axial compression). This structural squeezing action allows weak materials like masonry or unreinforced concrete to span massive gaps safely.
