The da Vinci Catapult makes a great science or history project. how to make eclipse box mod Make a Catapult. This is not an ideal design, so you don’t need to copy us exactly, you just need the basic mechanism. We first made a square of lolly pop sticks.

  • By doing this we store the potential energy of the catapult in the tension in the ropes and the arm. The tension is stored much like in a spring, therefore the equation of potential energy is the same as the for the Ballista. The k constant must be determined experimentally by find how much force is required to move the arm back a certain distance F=kx. The x is how far back the arm is stretched.
  • A torsion catapult, or mangonel, is a type of catapult used frequently in Medieval siege warfare. The mangonel works by twisting up a rope as tight as possible on the end of a throwing arm.
  • The action of a catapult uses tension, torsion and gravity. Like the catapults in Peter Jackson’s movie the “Return of the King,” catapults are siege weapons that hurl projectiles at …
