Since the class is going to build a trebuchet i thought it would be pretty cool to find some pictures and videos on the subject. Trebuchets are not exactly the kind of catapolts we are used to seeing. It is a catapolt and is one of the youngest. The trebuchet was used first in the second century AD by the Chinese. They became improved by the French and were very popular during the Medieval Ages. Trebuchets were used for castle seiges and were placed far away so that they could not be attacked by archers. They were not like other catapolts which used wound strings to launch projectiles. Tribuchets have a large weight on them that by using gravity launches a projectile. By using gravity they can launch pretty much anything. They are also able to move to any position to attack a weak spot on castle walls or even launch projectiles over and into castle walls.
