Hinged Medium Trebuchet
We made a few modifications to the design, adding some reinforcements to the axle, removing the wheels, and generally bulking everything up. We loaded up to 300 lbs. into this counterweight box, and we launched anything from a soccer ball to produce up to 200 ft. The pictures include our first attempt at a box-style hinged trebuchet. This design clearly worked much better than our previous version. While not perfect, suffering from excessive weight on small wheels and not enough clearance for the box, we learned some helpful discoveries in the process.
