What truss bridge design holds the most weight?
In this experiment we have tested which type of truss bridge is the strongest, yet uses the least amount of material. Two of the most used truss bridges are of the Pratt and Howe design. Through our experiment it was found that the bridge design that minimized the maximum compression force was the Howe Bridge.
How much weight can a balsa wood bridge hold?

How do you make a truss bridge stronger?
While connecting two sides, make triangles. If you really have time and want your bridge to be very strong, you may also divide each triangle to 3 smaller triangles. This will give additional strength to your bridge. You may also glue additional strips of pasta over the roadway.

What is the strongest glue for balsa wood?
Gorilla Glue takes longer than average to dry, but forms a strong and rigid glue joint. The glue foams while it dries and penetrates the balsa wood to create a better and stronger hold than average glues. This glue has a unique quality of using water to dry instead of an absence of water like other glues.
Can I use hot glue on balsa wood?
The problem with wood glue is you need sufficient glue surface and clamp pressure to make it work. Hot melt glue will adhere with a much smaller surface. Try it before you write it off.
Can I use wood glue on balsa wood?
Wood glues are fine for balsa.
While there are stronger glues, the added strength is usually unnecessary and strong enough should be sufficient.
What is Balsa cement?
Product description

What is CA Super Glue?
Cyanoacrylate glue is the industrial name for what is commonly known as “Crazy Glue” or “Super Glue”. In fact, the term cyanoacrylate glue generally describes quick-bonding super glues. They can be used to combine anything from metal to plastic and even human skin.
What is super Phatic glue?
Super Phatic is a wicking glue, in other words it penetrates close fitting joints and secures them well.
