Project Proposal

Project Proposal-

Image result for torsion catapultsJoey and I would like to build a torsion catapult. Basically you have your wood base and support bar. Unlike a trebuchet where the catapult works with counter weight this one uses rope/torsion. So as your pull back mechanism brings the arm back the rope becomes tighter and tighter. Once you unhook the mechanism the rope throws the arm forward into the supporting arm bar. When the arm his the arm bar the sling carries the object forewords then it flys out of the sling and becomes a projectile. Image result for torsion catapults
