rybak+bridge

well out of our class our bridge was the most efficient.we did the most simple design.it was just not high enough off the plain. the x's we had on the side of the bridge were there to spred the weaight through out the side of the bridge with the push and pull.it snapped on the side of the bridge. but it was still over 600% efficent so it just gose to show the best looking one dosent always make it the strongest one. the supplies like how much glue you use also playes a big role.
