Re: Elevated Bridge B/C

I would. I typically use a warren truss, which has always worked great for me. Go check it out online somewhere, just google it. The vertical members will provide support, and help keep the shape of your structure.

Re: Elevated Bridge B/C

My bridge of 8 grams held a decent amount to get me an efficiency of over 600. Unfortunately, the rope stretched and the bucket touched the ground at 600 efficiency, and when i released the pressure, two members broke. But i'm pretty happy with my design and bridge. Regionals is on Saturday! So i'm ...

Re: Remote Sensing C

Have they never been national champs from way way back? That's the impression I got from some of them. I know they're state champs, they beat us every year at State. I may have just heard them wrong. Either way, they're a strong competitor.

Re: Remote Sensing C

1) I'm homeschooled! So yeah :p. But i've found a great little study done by NC SO, so that will be perfect. There's not too much on forests, but this has a lot on it.

2) I never said they were RS champions, i meant just overall champions. At least that's what i've been told by them.

Re: Remote Sensing C

I've taken a couple practice tests. I got 50% of the one, which isn't bad, considering my sister got 50% at regionals and won (against Oak Ridge, national champs). Of course, the test was probably a lot easier. I was still unsure what to study afterwards. It's a broad subject! A lot of the test was ...

Re: Photocell Bonus

Hey guys,

thanks everyone! I actually managed to get it work, I used a very bright lamp. Now I just need to find a bulb that will be bright enough. I am using 4 AA batteries, and that seemed to work.
