Builiding a bridge

I gotta build a model bridge for my Honors Algebra 2 class at school. Any suggestions how to do it??

I was thinking popsicle sticks, but thats just me.

ALL Suggestions Welcome

I would think popsicle sticks would work just fine. Failing that, you could always use some strong cardboard.

does it have to be functional? be able to hold up a certain weight?

Look at my picture, I dunno if this would work for you but it's an idea.

I don't think its going to be graded on functionality, but It's gonna be tested with wieghts on it...

cool, we did a similar thing at a training course at work.

We were limited to a certain amount of building materials, they gave us a span that we had to bridge over and then they tested it by hanging a weight in the middle.

Think triangulation and truss like structural shape.....

circular objects are best for distorting weight...

for a tech class while i was at school we had to build 1 side of a bridge that spanned a 2 meter gap we used a lower arch and a upperarch with a triangle crossing pattern in the middle.

we made it out of 5mm x 5mm strips of wood and becuase it was so thin we could bend it causing it to have a high tension so it could be compresed with lots of load.

I have attached a scetch of the bridge that we built (please ignore my total lack of graphics skillz)

the top image (1) is a side view with the cross pattern and arches. (you will have to work out the best cross span for your design).

2) is the front view as you can see yet one more triangle meaning the force can be pushed downward over the supporting arch.

by the way we ran out of weights trying to test this bridge so if you are willing to put in alot of testing to work out the correct distances between triangles and where the bridges lower arch joins the central beam your bridge should beable to support alot of weight.
