About Trebuchets
Trebuchets are siege engines used in medieval warfare. They are sometimes referred to as counterweight trebuchets or counterpoise trebuchets. They were much more accurate than other medieval catapults and were favored for large sieges or breaking down castle and fortress walls. Trebuchets consist of a large arm with a sling attached which propels an object a great distance and is capable of causing great damage.

History
-
Trebuchets were used in the Middle Ages to smash through walls or throw objects over them. They could be found in China around the 4th century AD and around the 6th century AD in Europe. The contraptions appeared in Christian and Muslim territories as early as the 12th century. Trebuchets became obsolete for use in warfare around the 16th century, after the creation of gunpowder.
How a Trebuchet Works
-
Trebuchets take advantage of leverage to accurately hurl objects towards a target. The sling and arm of a trebuchet swing to a vertical position where one end of the sling releases and effectively propels the object forward, usually with great force. Troughs are located on either side of the device and are rotated in a particular direction for aiming.

Types
-
There are 2 primary types of trebuchets--traction and weight-powered. Traction trebuchets were developed first. They are powered by people pulling on ropes and were typically used for smaller attacks. After use, the beam is quickly returned to its position. Weight-powered trebuchets were used for larger sieges and is powered by a fixed weight attached to the beam, or counterweight. These trebuchets are extremely large and capable of launching objects up to 400 lbs in weight.
Misconceptions
-
Trebuchets are often confused with torsion engines, which were created first, and were smaller and less powerful. The torsion engine is powered by twine or twisted rope instead of using a counterweight and sling like the trebuchet. Both devices are classified as catapults, although they are completely different variants.
Models
-
Small model trebuchets are often constructed in modern times for science and history demonstrations. They are also created for hobby or even competition. Models range in size to 1/30 in scale all the way up to full size trebuchets. The world's largest model trebuchet can be found at Warwick Castle in England. It stands 18 meters tall and weighs 22 tons. The Warwick trebuchet was constructed from medieval drawings and notations.
