Re: Optics B/C

As a coach I wanted my team to learn something useful for this event. I taught them to draw their angles, bisect them, and draw the perpendicular line to place the mirror accurately. At regionals they were .2 cm from the target although the laser dot was .5 cm so measurement accuracy is questionable ...

Re: Storm the Castle B

The pictures we found of FAT trebs all show weights split on each side of the arm. The competition only allows one weight hung from the arm. It seems to us that a weight on one side only will twist the arm in the guide possibly causing it to hang or drag. How are FAT builders handling a single weight?

Re: Junkyard Challenge B

Has anyone tried to push their time at a competition into the 60.0 to 60.99 range? Yesterday my team did 59.97 at regionals and I was wondering if I should encourage them to go higher at states or do the event judges just say it went past 60 you're done regardless of the rules? It isn't the points ...

Re: Shock Value B

The values of the resistors that are given to you are nominal. All resistors have a tolerance. For example, the R5=100 ohms may have a 5% tolerance. That means the actual resistance measured may be as low as 95 ohms and as high as 105 ohms. The "theoretical" current and voltage drop across this ...
