Yea.. I’m in eighth grade, and we have to build an at least 80 cm bridge that can hold at least 30 lbs… within 2 weeks.

Does anyone know the strongest type of truss to use for a bridge that will be supporting a hanging a mass in the centre?

LOL. That would be my result!

What types of materials can you use to make a drawbridge that can hold the weight of many cars at one time?

I haven’t been lucky enough to see many drawbridges but up in Portland Oregon they are mostly steel (the parts that raise and lower)
and concrete at the pillars that hold the bridge up.

I created an expirement for my fourth grade science fair that tested both the flat truss and the warred truss using the exact same materials; balsa wood and glue. The flat truss held up 46.3 pounds of water, the warren only held 30.9. They both were across a span of eleven inches and in the end I only had chunks of demolished bridge…
