Quizplus · Accepted Answer

The transfer of stress from the center of an arch outward to its legs results in horizontal forces pushing outward. This can cause the arch to collapse or spread apart, which is why buttresses are often added to support and reinforce the structure. Columns and different types of arches may also be used in architecture, but they may not specifically address the issue of stress distribution in an arch.
