### Re: Elevated Bridge B/C

if you can find thhe right way to use an arch, then they work really well.
What kind of efficiency is "really well"?

### Re: Elevated Bridge B/C

State of Indiana (B) 1st - 2nd above -2000, 4th place-980. Yeah that was me, Valparaiso won with an efficiency of 2186. 6.86 g holding all 15 kg. Unfortunately we finished 3rd overall so we won't be at nationals. Some advice, you won't get above 1500 without doing the math and figuring out the opti...

### Re: Technical Problem Solving

So I take back what I said about probably not needing calculus in this event because on the regional test I took last saturday for a few of the problems it said specifically that you had to use calculus to solve them. We got them, but I felt bad for the younger ones in the room because that's not ex...

### Re: Technical Problem Solving

I thought of another good problem similar to some stuff we did in chem II. In an signifigantly large arrangement of perfect spheres stacked in the most compact way possible, what percent of the arrangement is empty space? I would say no calculus required like ever. Trig and basic stats is as far as ...

### Re: Technical Problem Solving

This event seems mostly to be interpreting graphs and doing trig/calc math. If you've had Trig/Calc, Bio, Phys, and Chem, I think you should be fine.
How do you think they are gonna have you use calc in this event?

### Re: Technical Problem Solving

Std. dev. is doable on a regular scientific calculator. There is really anything they can ask you to do. I'd say that knowing physics and chem is crucial and you also have to be able to think on your feet really well. This is definitely an event that favors seniors who have taken a lot of science co...

Our team is doing alright so far (same school as dickeyjones). We are coming along better than I thought we would since some underclassmen have stepped up to help make up for all the seniors we lost. Bottle rockets is the only building event I'm really worried about and we haven't launched the last ...

### Re: Elevated Bridge 2009

Umm she was almost definitely talking about the old rules for bridges since this is the first year for elavated bridge and there hasn't been a national competition with this event. The efficiencies this year are going to be lower than 3000 I would guess but 2500 is probably not out of reach for the ...

### Re: Trajectory B&C

I think our team calculated it to be about 55-60 degrees if you want it to be pretty safe.
