I used the fully elastic equation with our cord. Haven't gotten the opportunity to test if it matches the actual cord, though. I'll update you guys if I do get that chance.

Hi there everyone! Just thought I'd check in with y'all after my state competition down in Las Vegas. So I'm really upset with the running of this event at my competition. I originally had TPS and Astronomy on consecutive shifts. During lunch, they decided to move every event forward--but then in th...

Hi there everyone! Just thought I'd check in with some things I figured out only a few days before the competition, and how my state competition was. So, the equation doesn't work with masses at the extremes--and I can't believe I didn't realize this at all before. At low masses, the weight of the c...

Hi you guys, I'd like to check in with you all after my states competition last week. So my event was run by someone that really wanted us to have a great competition--but IIRC, he was only put in the event that morning. We explained both portions of the event to him during the event. We had a 3 que...

Lol, our states test for TPS had nothing of the forensic sort one might expect. My partner and I spent weeks studying bullet trajectory, blood splatter, thermodynamics, etc. Well, we had only lab to do at states...and it dealt with just analyzing momentum and impulse... -___- The scenario was a car...

Do you have any tips on reading absorption spectra? I know what they're supposed to look like and the standard absorption bands, but I saw a test recently that had cutouts from (I think) this picture and asked us to label OBAGKFM. Problem was, I couldn't distinguish between G5 and K0 (among others ...

Could someone please explain the hook thing? Im confused :( Whoops, thought I reliped to you last night... So each mass will be attached to a loop, as specified in the rules. But with some compound levers, it's difficult or impossible to actually hook them onto the lever. In order to solve this, so...
