Wind Power Div. C

wow...I was looking for a number I could punch into a calculator, but thanks for the equations. now I'm going to contemplate the answer to life. contact me in the next millenium...

if you can find the speed of the wind they provide you...then you can go through a few equations to get some answers.
and besides, you cant always just punch something into the calculator and get a number for everything you want. you have to go through several things to get a calculation...remember, its science olympiad, not special olympics.

Erm, I think he's just writing math incorrectly. I'm guessing "Vinfinity" means "V sub infinity" which would be written as V_infinity. "Vinfinity" as it is written would mean V*i*n*f*i*n*i*t*y.

sorry about the bad quotation. You got what i meant. if it doesnt make sense then its probably not what i was going for. its just easier to write it as one word instead of the whole underscore thing.

I was trying to clarify it for vofbassist, who thought it had something to do with the "number" infinity.

use the materials and build something that resembles a windmill, thats all i can think of

how are they going to measure how much power you generate?

you might want to ask someone thats good at mystery arch or another building event at your school for some help

They use a voltmeter. You have to create a windmill that can produce the most power at a strong and gentle breeze. I'd give some hints but seeing that we'll be competing with Boyceville, WI in 3 weeks...

I'll provide some hints in the near future, though.

Which team are you from? I have the results up on my computer and Mounds Veiw A got 812 between their strong and thier gentile breeze. Our team didn't do very well, but we didn't practice very much.

Edit: Sorry, teams. All three of them did bad. From highest to lowest it went: C, B, A.

Yes, I'm from Mounds View B. I was the event leader for our three teams because I was the only one who had experience at Nationals this year. Surprisingly, I taught my team mates quite well. They took first and third where I took fourth... I was hoping my partner didn't cut up the manila folder but it was too late.

Manila alone works very well for wind power. It is strong enough to withstand the power of the wind so that it does not hit the stake compared to the plain paper. When it hits the stake, it slows down the speed of the fan. Also, I found out that placement of tape varied with the speed of the fan. It can be something to play around with. And, we folded curves so that it can catch more wind. We found that it increased the speed significantly.

We won't be seeing Wind Power again in Minnesota. It was a really fun event.

And initially, our goal was to reach 400. At Nationals, we got around the late 300's and made it to 10th place. A score of 812 from one of our team members was outstanding. I should have went with my instincts, but experimented with plain paper first... You don't even need the plain paper.

Could we get some ideas for the shape of the fan? Right now we're working on a cone shaped one. It looks kinda like a drill.

[Grace]

4 blade pin wheels seem to work very well. That's what all of our three teams used. By not cutting the blades separately, the fan seems to work efficiently. So try to keep your blade design intact. I'm not sure what a cone shaped fan would look like...
