Label the parts of the diagram using key terms from the lesson. A labeled diagram of an arch. The very center stone of the arch is labeled A. The stones of the curve are labeled B. The stones of the straight portion are labeled C. The direction of weight thrust is on the B stones. The springing point is on the C stones. Look at the diagram above. Label parts of the arch: A, B, and C.

Short Answer

The keystone is the essential component of an arch, securing the other stones and maintaining stability. Voussoirs, the wedge-shaped stones, ensure even weight distribution, while springers are at the base, marking the start of the curve and supporting the arch’s structure.

Step-by-Step Solution

Step 1: Identify the Keystone

The keystone is the key component of an arch, positioned at the very top center. It is crucial as it locks all the other stones in place and ensures the entire structure remains stable. Without this central stone, the arch would not be able to bear weight effectively.

Step 2: Understand the Voussoirs

The voussoirs are the wedge-shaped stones that line the curve of the arch. Their unique shape allows them to fit together tightly while distributing weight evenly across the structure. This helps transfer the load from the keystone downwards towards the supports.

Step 3: Recognize the Springers

The springers are the stones located at the base of the arch. They mark the point where the arch begins to curve and sit on the supports. Springers play a vital role in holding the arch in place and help to manage the vertical load from the arch to the ground.
