rock :
I have money wagered on this contest, so it is important I get the best design.
RULES:
I can use any kind of commercial brand pasta
The bridge must be made solely of pasta and glue.
Winner is the legal bridge with the highest official load divided by bridge weight (most efficient).
I guess I didn’t make this clear. I too had a balsa wood competition in 8th grade and came in first place (what school did you go to? do i know you?).
Anyways, I want the diagrams of the exact design.

Use Long strand Spaghetti and design a truss Bridge!
Use lasagna sheets, you know, for the bottom. Then like, linguini or something thicker than spaghetti for the rest of it.
I
did the same thing in 8th grade with balsa wood and glue.
Key: Triangles are the strongest shape.
I’ve always wanted to do this: shred up the pasta and mix it with the glue to form a sort of cement mortar. Then fill a mold lined by pasta with the mortar and let it dry…
This type of bridge should be able to withstand a lot more than a tensile bridge.
If you want to run an experiment on the strongest pasta it’d be easy to buy a few different brands and set them on the edge of a table underneath like, a book or something. Then hang weighs on the ends until they break, the ones that can hold the most weight are the strongest to use for the bridge. I’d take a guess and say rice noodles would be the strongest, especially since they would turn to mush in the glue and solidify into a single block
Grinding the pasta into powder and using it to connect the polymer chains in the glue into a network will work a lot better than gluing together pieces of pasta; build an arch bridge that way, and viola.
If you want a diagram, look up an inverted catenary curve. Build an arch like that.
