Quizplus · Accepted Answer

When a load is placed on a properly arched structure, the arch distributes the load uniformly across its curve, which causes compressive forces to act on the structure. These compressive forces strengthen the structure as they are transmitted along the curve to the foundation or abutments, resulting in increased stability and load-bearing capacity. Therefore, compression strengthens the structure.
