Trabuco was a weapon used in the Middle Ages in the time of war. It was used to throw huge stones over walls much like a catapult. During war, the opposing country could throw 140 kilos at extreme speeds over the adversary’s heads from 800 meters away flawlessly. A gruesome act also happened during war. They would fling very sick people to the enemy in hopes they would get sick too.
Trabucos were created in China around 400 BC. In 600 AD Europe started using Trabucos during their wars. The practice of using them stopped when gunpowder was invented. The difference between catapults and Trabuco was that it was simpler to use and it was easier to make. The way the war machines work were transforming potential energy into kinetic energy. The counterweight was equivalent to the momentum of the projectile so the weightier the counterweight was, the projectile would be more powerful.
