I just edited the wiki for this year check it out and tell me what you think. How do I put in a table of contents. I am not quite finished yet.
What materials have you been using I want to see what I need to do differently.

um... I am not saying that you are wrong but are you sure you got a cantilever to go 49cm out? And if so, what did you use for the lever, or thing that hangs off?

Your tower should be taller than that. It is very short in comparrison with your other structures. how did you make you cantilever and bridge so long.?

our groups tower, bridge, and cantaliver are all built the same way. i promised my group that i would not revile how we built them. we used duct tape as a counterweight, is that allowed?

Most are prabably built the same/similar technique.

There is no rule against it. Will you have enough left for a counter weight when you structures get big enough. We just use all of our extra supplies.

This is my first year of competing and i was wondering if any of the veterans had any advice. My partner isn's doing much , so I'm doing most of the work. Please and thank you :!:
