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.

[disownedpear]

Bridge:98in
tower:50in
cantaliver :49in

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?

[Littleboy]

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.?

[disownedpear]

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.

Regarding these scores, what is it holding? After all at the compition it could be 1 of 3 possiblities. As for these scores, this was while holding a golf ball.

Bridge: 6 feet
Tower: 7.5 feet
Cantilever: N/A

Does anyone know if duck brand duct tape metallic??

Duct tape is normally made with plastic (vinyl), cloth strands (cotton), and adhesive.
It is not magnetic and not metallic BUT, it is unclear if the prohibition on metallic tape is intended prevent duct tape from being used.

The only truely metallic tape I am aware of is used for heater ducts (hence the confusion) but is actually called muffler tape.

Maybe you should submit a clarification if you plan to use duct tape so you can find out the intent

so far:
Bridge: 123" (10'3")
Tower: 82" (6'10")
Cantilever: 6'0" (72")

all held all three balls, all built in thirty minutes with materials that fit in box with appropriate dimensions

new tower height:109 inches

[Littleboy]

how do you guys get your balls up on the top of the tower? The Soinc FAQs say that you cant stand on a chair or someones shoulders and that stuff but then we have trouble getting the balls on the top
our bridge is excellent.

I understand a ladder will be made available to place the cup & ball if asked to build a tower...
