Also known as Trabuco, Trabucos is a siege weapon that was used in the Middle Ages for crushing masonry walls or even firing projectiles and it resembles the catapult. At times, it is also known as the balancing Trabuco so as to differentiate it from another weapon which is the traction Trabuco, which was created before Trabucos. A counterweight blunderbuss, Trabucos first appeared in Muslim and Christian nations around the Mediterranean. The weapon could throw 140 kilos worth of projectiles at high speeds to enemies who were over 800 meters away. The
Trabucos were first invented in China approximately 400 BC and were introduced to Europe about 600 AD according to veja.abril.com.br. Trabucos were abandoned during the outbreak of gunpowder.
The mechanism of Trabuco consists of transforming the energy potential into kinetic energy. This mechanism is derived from the sling. Trabuco uses the mechanism that the size of the counterweight is normally direct proportional to the projectile velocity, since the larger the counterweight, the powerful and stronger the launched projectile. The invention of Trabuco comes from the old sling which contained a tiny piece of wood meant to extend the weapon and to offer a better lever. Through the traction bolt of the Chinese, this weapon evolved to make it more effective and accurate. There is a smaller form of Trabuco that has a smaller extension but more portable and a smaller time interval in between the launches on tudo-sobre.estadao.com.br.
Most Trabucos were however designed in bigger sizes and needed about 15-45 men to be able to handle them. The people who operated the siege weapon were the local citizens who assisted in the attack in the defense of their city. The smallest Trabuco could however be operated by one man. The first ever clear record of a Trabuco was from an Islamic scholar known as Mardi Al-Tarsus according to pt.wiktionary.org. The scholar wrote about Trabucos being machines that were invented by unbelieving demons. Trabucos were last used by the Hernan Cortes in the year 1521 during the attack of the Rhodes. Today, Trabucos are used as a form of fun and for the explanation of crucial principles of mechanics. It can now be found in museums as a type of weapon that helped in winning battles over the centuries.
