Also, the newfound stability meant that the trebuchet did not have to be repositioned after every shot, so firing time improved to about twice per hour [6]. This is why more than one wheel is used. Has been printed on a MiniFactory and works almost out of the box, some filing or sanding requred. Larger trebuchets would have large 'hamster' style wheels on the side of them, allowing men to run inside them to winch down the large arm where the projectile would be added, a pin would then be removed throwing the large arm upwards.

On one end of the beam was a nest, sling or other element for holding the payload attached and on the other end several ropes for men pulling down the beam in order to provide enough force to propel the payload. An Introduction to Gear Modeling in COMSOL Multiphysics, The Motions and Mechanics of a Truck-Mounted Crane, Multiscale Modeling in High-Frequency Electromagnetics, All of the components are assumed rigid (including the sling), All hinged joints are assumed frictionless, The projectile is prevented from falling through the ground using a penalty stiffness, The counterweight hangs from a beam of length, The swinging arm is 6 meters in total length with.
