does the arm that holds the sling need to be elastic? I have a trebuchet in the making and I'm contemplating how to make a proper sling without the projectile staying in the sling...

Its not that i cant build the trebuchet..its that i get so confuse on were to put the release point or wat i should use. Have any suggestions?

Multiplied your measurements by 4 to make a killer trebuchet, still in the making but thanks for the plans.

thx

the counterweight should be atleast 80 times heavier than the object your slinging.
WootMapler (November 30, 1999 at 12:00 am)
yes.

yup, its been done before. I'm sure there's something on YouTube 'bout it.

Hi 'Skull --
Water balloons should work just fine because there is no slamming pressure or force with a trebby -- unlike a catapult that has an arm that comes to an instant stop while the projectal SP continues on.
The science is all in the size of the arm and the weight of the bucket of rocks, etc.
I would think you need to make one about 7 feet high to pitch water balloons.

Do you think it would be possible to build a trebuchet that would launch water balloons? That is what I am going to try and find out for my science fair. The only factor I am worried about and considering is that the water balloon might simply pop the moment too much force is applied to it. |
