Table Top Trebuchet

Download/DVD: http://hilaroad.com/video/
This video explains the science behind a trebuchet. The trebuchet is a medieval machine designed to throw objects at or into castles. This video explains that the gravitational potential energy stored in the raised counterweight is converted into kinetic energy in the projectile. Trebuchets make excellent science fair projects. Plans for building the trebuchet featured in this video can be found at

Congratulations! Thanks for posting this video. It´s very useful for science teaching. Very good!

if anyone wants to build a trebuchet you should know that if you put wheels on the bottom it throws objects farther

that is really cool. i am making a big one for physics class. it is about 7 feet tall to the fulcrum. im going to have about 150 to 200 pounds in it. the throwing arm is 12 feet long with the long end being about 8 feet. i was wondering how big/long to make the sling. do i make it as big as the long part of the arm or is yours like that because it is small.

awesome, approximately how far do you think it would throw a tennis ball? cuz that's what my science project has to do.

hey i watched ur video and we did that same thing in school but in a different design ours used heavy washers instead of ur weight and we had 2 places to put the weights soo then the closer it was to the middle, the farther it went,and the farther it is, the higher it went we used basicly the same desgins as you did (not EXACTLY the same)

HI

I watched your video!

How far does the table trebuchet go??

Would adding a pulley along with the counterweight make it go further?

I am doing a class project and the requirement is 12m. So I would like to go more than 12 m incase.

When loaded how long and how high is it?

[awilhelm12]

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.
