To create the Trebuchet Catapult is necessary to know the strength of the stick when bent, compressed or pulled. For this you need to make bodies of evidence, which is nothing more than the likely ways that the sticks will be mounted and thus with the tests, we will know how much they resist. This is essential in the construction of Trebuchet, because the weight of the lever arm will force the entire structure, which moreover has to bear its own weight. Therefore, from calculations similar to a truss system, it is possible to determine how much force is required of each toothpick and thus form the structure of our catapult.
