How do you make a really strong balsa wood bridge? - how to make a bridge out of balsa wood without nails or glue
ok so I have a bridge made of balsa wood ..
What are good design and a solid structure?
I need some details, and perhaps links.
I know that the triangles are the strongest, but what can I do to ensure you have a good amount of mass before the break? Thank you.

How To Make A Bridge Out Of Balsa Wood Without Nails Or Glue How Do You Make A Really Strong Balsa Wood Bridge?

Do not open rectangles, are weak and tend to reduce it. Use rectangles with a diagonal the corner connecting member opposite. This is divided into two triangles, a lot stronger.
Bridging as quickly as possible.
Bridging the highest. This increases their 2nd Time zone for vertical bending loads, which means a certain load, producing less stress.
With material from what I can. The largest bending stress is in the middle of the bridge (assuming that is where the force is applied), so that the deck a bit thicker (and higher) in the middle. A cross-section at high short-term runs the length of the bridge cone is a good idea if you miss material.
Align the plan bALSA wood vertical (aligned with the load). It is much harder and stronger in the plane of bending as bending from the plain.
Use a piece of balsa wood to make it short and robust.
If the members of the train or in print, no lateral forces.
Study beams and evaluation of Bow.
