Check out these trebuchets that people built and see how they compare to the simulation results on
Both of my two older kids are in high school physics and I decided that we needed real work application of concepts. So we built a 10’ throwing arm trebuchet. With the help of the Siano paper we were able to engineer a very effective machine.
VirtualTrebuchet overestimated the actual distance by 5.5%.
This website was one of the best things that helped with my trebuchet. I had built a trebuchet but without the help of this website, it probably would have turned out horrible. Thanks to whoever the designer of this website may be.
VirtualTrebuchet underestimated the actual distance by 28.5%.
Medium sized trebuchet w/ ~300lb counterweight launching gourds. I optimized some of the dimensions using this site, and I was happy to see that we were able to get relatively accurate results when we were doing some test firing.
VirtualTrebuchet overestimated the actual distance by 7.2%.
