Re: Elevated Bridge B/C

I saw the strangest design at regionals. It was an arch bridge were thee frames were close at the center, but he bent them so the frames were much farther at the base. DOes that effect the strenth or was it just a crazy experiment? I had an event when it was being tested

Im sorry for making a gross oversimplifications :( Im not too good at this yet, this is my first year an...

Also @ everyone who thinks arches is a good idea: At Invitationals I but a bridge with an arch and They have to be PERFECTLY SYMETRECAL or the shorter arch will take a majority of...
