	The trebuchet (sometimes "trebucket", but that is less common) is essentially a lever supported by an axle through upright posts of a frame, closer to one end than the other. The long end has a sling resembling a handheld [[sling]] and a release pin. The short end has the counterweight, which is many times more massive than the mass of the object to be thrown.

	The ~~bjective~~ is to apply the energy of a large mass slowly falling for a short distance into throwing a relatively small mass at high velocity for a long distance.		The objective is to apply the energy of a large mass slowly falling for a short distance into throwing a relatively small mass at high velocity for a long distance.

	The two main counterweight designs are "fixed" and "hinged". The fixed type has the weight solidly fastened to the end somewhat like a hammerhead. The hinged type suspends the counterweight from short vertical bars that are hinged at the short end of the lever and (preferably) at the point where they attach to the counterweight itself. The advantage of the hinge suspension is that as the counterweight drops during the firing sequence, it follows a more nearly vertical path rather than an arc.

	===Advantages===		===Advantages===
	A trebuchet can be extremely accurate (particularly the fixed and counterweight types) because successive shots can land in a relatively small grouping, and one can make adjustments to either the pin angle or the sling length or both to obtain better results, which may then be repeated with consistency provided the ammunition is consistent in both mass and volume.

	Trebuchets can be scaled up in size for throwing very large projectiles, more easily than onagers, ballistae, or arbelests. Hence the nickname of "the atomic bomb of the Middle Ages".

	Traction trebuchets have a very short reloading time because you do not need to winch the arm down to prepare them for firing. For SCA combat, this allows a rapid rate of fire.
