Arches or beams?

  1. Apr 19, 2008 #1
    Why do pasta bridges made with arches or triangular peaks hold more weight than those made with a flat beam? Assume the weight is attached to the base or deck of the bridge.

    An arch is inherently the strongest structure in nature, and a triangular arrangement is a reasonable approximation thereof. It has to do with how stresses are distributed. An engineer should be along shortly to give you more information.

    That does make sense. Thank you for the input!
