means no hinging too huh? ;)
it's nonsense ether because you don't limit weight of frame so it can be +inf density.

why you draw box not using grid and at -2000 coordinates? :wtf:

You gave us a .061kg projectile and a 2000kg CW limit. That's a 33,000:1 mass ratio. Really big trebs people build for actual Punkin Chunkin have an MR of about 3000:1 max, and throws are usually performed at more like 1500:1. So first things first, heavier projectile please (or lower CW limit).

Note that it's possible to throw really far with actually a quite low MR. A couple hundred to one is more than enough for efficient treb designs.

How does a 500 kg counterweight limit sound?

How about look into similar contests first and into game itself before start any contest :D

this doesn't break any rules. it is not fixated, it is just infinity density.
it throws the ball so far hat it hits the roof.

this is a cool device that doesn't really break any rules, but it doesn't look like a traditional catapult.
it is really cool, and it can throw the ball so far that it will hit the killer plane on top..
