How to Build a Catapult. As Jason and I walked the shop floor, trying to picture how to layout the frame, we came up with this:The base of the frame would be 3' x 8' and made out of 2X4'sThe frame would be shaped like an off-balance "A"The frame will be 6' tallLay out two of the 8' 2X4's on the floor, and space them 4' apart.

How to Build a Catapult

Cut two 3' sections of 2x4's on the miter saw and lay one of them on one end of the frame.Lay the other 3' section about 2' in from the end of the 8' sections, this is so that when the arm comes forward, it doesn't throw the whole 'pult forward as well. Cut the 4X4's to 6' in length, and stand them up so that they are on the inside of the frame and flush up the indented 2x4. Cut one length of 4x4 to 3' and save it for later - this will be used as the cross-brace at the top.

All about Catapults. Catapult Physics. Catapult physics is basically the use of stored energy to hurl a projectile (the payload), without the use of an explosive.

Catapult Physics

The three primary energy storage mechanisms are tension, torsion, and gravity. The catapult has proven to be a very effective weapon during ancient times, capable of inflicting great damage. The main types of catapults used were the trebuchet, mangonel, onager, and ballista. These types of catapults will be described, and pictures and illustrations will be included. Catapult Physics — The Trebuchet Source: Wikipedia via ChrisO A trebuchet is a battle machine used in ancient times to throw heavy payloads at enemies.

Among the various types of catapults, the trebuchet was the most accurate and among the most efficient in terms of transferring the stored energy to the projectile. A trebuchet works by using the energy of a falling (and hinged) counterweight to launch a projectile (the payload), using mechanical advantage to achieve a high launch speed.
