Project Proposal

Image
Project Proposal- Joey 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.

Week 14 Thursday

Today the rope ended up snapping and breaking on us as of right now the catapult is out of commission until we retrieve more rope. we added more wood support beams 4 X 4 across bottom of the cross bar and two 2 X 6 X 18 on the outside of catapult so that the wood did not snap on us again. i added eye hooks on back 2 X 6 board as our release mechanism. we also added three more 2 X 4 on top of post so the arm stopped earlier and launched the object in to the air.
