This is a brief tutorial on trebuchet physics and useful tricks to make your trebuchet throw farther. Much of this isn't obvious if you're new to trebuchets and I overlooked many of the key energy transfer methods when I was starting out. Hopefully, this will help you optimize your trebuchet

In this tutorial, I discuss how to use sling stalls and CW-arm stalls to your advantage. Having a basic understanding of both is necessary when designing an efficient trebuchet.

For the purposes of the tutorial, I made a tabletop hanging counterweight trebuchet. This means that the tutorial will primarily focus on Hanging Counterweight trebuchets, but the concepts also apply to floating arm trebuchets (once you have the rail gaps worked out, a floating arm trebuchet is like a hanging counterweight trebuchet with greater fall distance and a vertical CW-arm stall point... hence, it is far more forgiving...)

Also briefly mentioned is the multiple rotations trebuchet, where a link is included....
