Engineers: Best Bridge Structural Efficiency?

Joshy asked:


Hey guys,

I am creating a bridge out of 3/32″ Balsa Wood, and need to give it the best structural efficiency.

I have asked this question before, but got minimal replies.

Which type of bridge has more potential for great Structural Efficiency, meaning, what design can I use that will be very light, and carry the biggest load possible.

To put this into perspective, I need to carry a maximum load of 15,000g (15KG), looking for the total mass of the bridge to be about 10 grams.

These numbers are not exact, and I dont need to hold the biggest mass, I just need the best structural efficiency (E=Max Load Supported/Mass of Bridge)

Thanks for looking, I only have a couple of days to do this so any tips are appreciated!

There is a general wiki article with the types of bridges =D
