Which term is not part of masonry arches?

• A. Voussoir
• B. Keystone
• C. Abutment
• D. Quantum

Answer: (D)

This question tests your knowledge of terms used in masonry arches. In a masonry arch, the wedge-shaped blocks that make up the curve are called voussoirs, and they transfer the load along the arch to the supports. The keystone is the central voussoir at the top that locks the arch in place and stabilizes the whole curve. The abutments are the supporting walls or structures at the ends of the arch that resist the horizontal thrust generated by the arch action. All of these are fundamental parts of an arch. Quantum is not a term used for any component of a masonry arch; it’s a word from physics (or general usage meaning a quantity) and has no role in arch construction. So the term that does not belong is Quantum.
