Homework Help: Balsa Wood Bridge

  1. Feb 9, 2005 #1
    Can anyone or does anyone know where I can get a good explanation of how to figure out how big an arch should be for a bridge?

    I am thinking of making one for our competition, and if I can't get that to work right, I will switch to a king post deisgn.

    Oh, and is it true balsa and other types of wood are better in tension than compression because the cell walls will lose compressive strength if the water is taken away?
