So you get penalized if it doesn't go all the way back

Yeah isn't that automatic tier 4? But what if it only goes back a few meters?
Tier 2, but that is still not good.
In response to your first question:
I meant it is Tier 2 not Tier 4, which still hurts your chances.

In response to your second question:
It just has to back up a noticable amount to be Tier 1.

That was what I was wondering, thank you.

As for the tier thing, I got confused because the last people who built our mousetrap were tier 4, but I guess they had a building violation in there.

Man, I sure wish I had a copy of the rules. Well that's probably the only good thing about school starting tomorrow, that I will be able to get one...

3.f means that the distance between the two axles has to be between 30.0cm and 34.0cm, correct? It seems to be outlined clearly, yet I keep questioning it.

I'm using CD's as wheels, but when I did my calculations, I got the result that my bar would need to be around 60 cm long to travel all 14ish meters. Am I doing something wrong, or do I actually need that long of a bar?

### Re: Mousetrap Vehicle C

What kind of design are you using?

If you have 2 mousetraps in opposing directions, then the bar only has to be 30cm to travel 7m in each direction.

Oh, I'm using the 2-mousetrap powering with fancy winding, so you have two bars each 30 cm, so I guess it makes sense if I have one that's 60.

I put this little circular thing in on the base in front of the axle so that it would wind straight. You could use a piece of a straw but the string would probably cut through it.
wouldn't that still be loose even with a straw? how does that get me a consistent wind every time?

use thinner axles
and that is split with 2 mousetraps
