Trebuchet Models

We decided on four differemt models. These are the "black box" trebuchet, a see saw trebuchet, a trebuchet with a hinged counterweight, and a trebuchet with a sling. We decided to use these, in part, because they are (some of) the models used by Donald Siano in his paper "Trebuchet Mechanics". You can download it from The Algorithmic Beauty of the Trebuchet. The models, of course have some unrealistic qualities. First, there is no friction. And, second, all of the parts are rigid. The lengths and angles used in the models are as follows.
