Re: Materials Science C

Could anyone explain how one might determine the packing structure of a particular material (i.e. FCC, BCC)? The question is asked several times in the Clio Invitational test that was posted a while back and there are no explanations given. Unfortunately, that one is something that you sort of have...

Re: Materials Science C

WA had a lab on contact angles. We got four different surfaces, and had to compare the contact angle between them, draw the drop etc. We also had to model one of the crystal structures (each team got a different one).

Re: Materials Science C

It's there now. There is a mistake on your answer key. For question 10, you are supposed to list materials in order of increasing Young's modulus. However, the answer key has "rubber" twice instead of having "diamond" in its proper spot. Everything else looks good though! Thanks for the test, it wa...

Re: Astronomy C

Has anyone looked at the test exchange at the Northview 2013 test that could help me on #1? I understand where the formulas come from, but I don't understand where d= 1/.00589^11 came from. I don't understand why the paralax angle is now a decimal, being rasied to the 11th power. Any help? Its not ...

Re: Materials Science C

I'm curious , what was the lab at the Regional Competition? At most invitationals, I have not seen a lab and it has been only a paper test (not entirely within the spirit of the rules for the event). When I ran it at the Northview competition, the lab portion involved measuring and plotting Young's...
