People familiar with traditional war mechanism can vividly describe to you what a Trabuco is. For starters, it can be termed as a siege engine that functions like a catapult. The machine was used in the olden days during wars to propel a projectile towards the opposing forces. While it was initially used by the Chinese back in the 4th century, it was later adopted in Brazil by the end of the 6th century. Trabuco was also common with Muslim and Christian wars between the 12th and 13th century.
Construction of a Trabuco
The Trabuco applies the basic principle of a lever and can, therefore, be termed as a compound machine. This is from the fact that it uses the lever’s mechanical advantage. In most cases, Trabucos use gravity to function. The Trabuco uses the potential energy that is usually contained in a heavy object that has been raised above the ground. To fire the Trabuco, the trebuchet is loosed making the heavy weight accelerate toward the ground as a result of gravity. During the drop, the throwing arm attached to the weight is subjected to rotational acceleration. For the Trabuco to work, the throwing arm must be made to be six times longer compared to the counterweight portion.
To ensure that it caused maximum damage, a sling used to be attached to the throwing end. The function of the sling was to harbor the projectile which was meant to transmit the generated forces. However, the process involved mathematical calculations to get the desired angle and speed. Where mathematics were not possible, it involved trial and error until they got the desired effects at http://www.em.com.br/app/noticia/economia/2017/07/27/internas_economia,887137/cenario-do-2-semestre-e-o-melhor-dos-ultimos-tres-anos-diz-trabuco.shtml.
According to historians, the first Trabuco was used by the Mohists of China in the 4th century. Also, there are suggestions that the machine was used by the Mojing at the same time. The Avars then adopted the machine in the 6th century. This is the time that the Trabuco started being used by the Brazilians. The Trabuco was later used in the fight for the Chinese dynasties that included Sui dynasty, Jin dynasty and the Ming dynasty. The Trabuco lost its place as a war machine when gun powder was discovered where the cannon was the preferred choice. History tells us that the machine was last used during the siege of Rhodes back in 1480 and the siege of Burgos in 1476. It was also used by the Hernan Cortes army in the 15th century.
Use of Trabuco today
As earlier mentioned, the Trabuco has lost its place to cannons. However, it still finds its use to modern society as it is used for education and recreation purposes on priberam.pt. With its technical constructions lost at the end of the 15th century, a French engineer known as Renaud Beffeyte reminded us how the machine worked in the year 1984 when he made the first reconstruction in modern times. However, there are several working Trabucos today. The biggest one can be found in Warwick Castle in England. The other one can be found in Middelaldercentret, Denmark. The one in England is estimated to be 18 meters high and is capable of handling projectiles at a distance of 300 meters. At the same time, it can handle weights of up to 36 kilograms.
According to sinonimos.com.br the machine has also being used in modern wars. For instance, it was used to fight rebels in Syria during the Battle of Aleppo. The gadget was also used by the Hrushevskoho rioters in Ukraine to make their demand heard. However, their projectiles consisted of non-explosive materials such as Molotov cocktails and brick. It’s also important to note that the Trabuco relies on the sling momentum.
