Storm the Castle B

[knittingfrenzy18]

Agreed

Dimensions: 120′x107′, ceiling height of 27′ to the rafters (32′ to the actual ceiling)

Got 5th in region because the people running the event gave us a 1kg counter weight saying that it was 2kg with a 50 gram ball.

[quadmaster]

Our projectiles at states were this: http://www.toywiz.com/angrybird3yellow. ... nQodHUZQAQ
and this: http://www.toywiz.com/angrybird3pig.html . Cute and all, but the yellow bird fell 4 and a half meters short of what we predicted (when our test projectiles all fell within a meter of each other at that mass ratio) and then on the second shot fell out of the sling and went backwards.

It's not like our team was incompetent. We had done over 90 test shots, and once we knew just how badly these flew, we managed to get the green pig (which at least was approximately spherical instead of approximately a frilly beaked triangle) in the box at 15 meters on the first try.

Is there any chance we can get the judges to decide on the type of projectile next year and announce it beforehand? I'd be a lot happier knowing the projectile would be a water balloon with an unknown amount of sand in it (with the amount of sand announced after impound) rather than it being anything "approximately spherical" and "under" 6 cm.

Why do I put "under" in quotation marks? because at regionals we were presented with a 7 cm diameter tennis ball, and the angry bird plushies we were given at states are clearly labelled as "three inch."

Our State was the same projectiles and Counterweights. A hamburger dog toy and a messed-up tennis ball with a 1kg and 2kg Counter weight.

Heyy guys....
The rules state that the counterweight must fit in a 20x20x20 box but on the NY state and the Eastern Long Island Regionals and National as I remember, they used a counterweight which has the building directions on soinc.org (http://soinc.org/sites/default/files/Ho ... 120106.pdf). What if the event supervisor makes a plain or box with the hook inside it. Then to put that box on my trebuchet, or even some other trebuchet would cause it to tilt, in my case disqualifying me. What sould I expect? FYI I have done Strom before so I know the event supervisor well, so I saw the counterweight before.

Does anyone know how big the building will be for nationals? Hight and Length?
Here is a link to it: http://www.scienceolympiad2012.com/tour ... he-castle/

Doesn't it say the dimensions at the bottom of the page you linked to?

um well little bit of a fail... look underneath the pics it states the dimensions very clearly

[Wil4+1]

Any story of your device at Nats?

[knittingfrenzy18]

Uhhhhhhh, yeeeaah.

(Not that I'm on the StC team, but I watched it.)

So we were all perfectly ready and fine and ready to place high! However the people driving the trebuchet got cut in front of and crashed by some guy. They think it was intentional, but we don't know.

Anyways the arm broke and they had to reassemble it.

And at the competition, when they wanted the dimensions, they wanted it in firing mode. So they had to add a heavy bolt to one side of the arm.

But that wasn't what got us 53rd place.

The guy's dad said it was because when they reassembled it, they had tightened something too much, making more friction than there was when they calibrated it.

Oh well.

Oh and the guy's dad said "Fix that [whatever key thing that you pull out to launch it] for next year." It was because they couldn't get that in because they didn't get 4 shots--they almost had it but they ran out of time and only got 3 in.
