SUMMARY
Arch bridges are structurally superior to beam bridges due to their ability to distribute weight more effectively. In a pasta bridge, the arch shape allows for compression forces to be directed along the curve, enabling it to support greater loads compared to flat beam designs. Pasta, being a brittle material, is stronger in compression than in tension, which further enhances the performance of arch structures. The arrangement of pasta in an arch maximizes its load-bearing capacity, making it a more efficient choice for bridge construction.
PREREQUISITES
- Understanding of basic physics principles, particularly forces and load distribution.
