The analysis of arches focuses on their structural efficiency and the transition from bending to axial compression under loads. Key differences from prior concepts include the utilization of polar coordinates for equations. Arches, particularly parabolic and semi-circular forms, serve as economical solutions for spanning large distances, capitalizing on materials optimized for compression while minimizing bending moments.
