Modern Trebuchet

I made a modern version of a trebuchet. on the threat fits a(or 2) m20 nut(s) and you can best throw a ball out of a bearing (diameter is 8mm). This product is designed according to physics and various motion equations and optimized with Matlab. it fits in a 30x10x5cm box (designconstraint) and and has less then 150cm^3 material (another constraint). I have, together with my group of designers/future engineers, made a report about this.
