Physics project. Carried westward by the Avars, the technology was adopted by the Byzantines in the late 6th century AD and by their neighbors in the following centuries. De korte kant van de arm heeft een zeer zwaar draaibaar contragewicht van minstens enkele tonnen. Trebuchet is een Oudfrans woord, dat is afgeleid van het Oudfranse trabuchier "vallen". The projectiles were several feet in diameter, and when they fell to the earth they made a hole three or four feet deep. The rotation speed of the throwing beam increases smoothly, starting slow but building up quickly. Chevedden, Paul E.; et al. A trebuchet[nb 1] (French: trébuchet) is a type of catapult[3] that uses a long arm to throw a projectile. The entire argument for the existence of hybrid trebuchets rests on accounts of increasingly more effective siege weapons. 5 ingenieurs en 49 timmerlieden waren drie maanden bezig om het gevaarte op te bouwen. [58] In 1989, Middelaldercentret became the first place in the modern era to have a working trebuchet.[58]. The difficulties of coordinating the pull of many men together repeatedly and predictably makes counterweight trebuchets preferable for the larger machines, though they are more complicated to engineer. The first is the traction trebuchet, or mangonel, which uses manpower to swing the arm. Of this, the Hongwu Emperor stated in 1388: "The old type of trebuchet was really more convenient. [38] Possible references to counterweight trebuchets also appear for the second siege of Tyre in 1124, where the crusaders reportedly made use of "great trebuchets". De trebuchet kan per uur tot 2 projectielen van 90 kilogram 300 meter wegslingeren. The record-holder in that contest for trebuchets is the Yankee Siege II from New Hampshire, which at the 2013 WCPC Championship tossed a pumpkin 2835.8 ft (864.35 metres). [62] A more radical design; Jonathan, Orion, and Emmerson Stapleton's "walking arm",[63] described as "...a stick falling over with a huge counterweight on top of the stick..."[64] debuted in 2016[65] and in 2018 won both the Grand Champion Best Design and Middleweight Open Division of the 10th annual Vermont Pumpkin Chuckin Festival. [12][23] The rapid replacement of previous siege engines was probably made possible by the deterioration of artillery expertise in the late Roman Empire. Vroege slingerarmen zoals de hierboven geschreven machines werkten volledig op trekkracht, maar de trebuchet werkt volledig op zwaartekracht; het zware contragewicht levert de benodigde energie.

Long before the development of modern artillery, bow and arrow were the only items of weaponry used, in addition to hand held knives and spears. wordt een dergelijk apparaat beschreven. They were used as defensive weapons stationed on walls and sometimes hurled hollowed out logs filled with burning charcoal to destroy enemy siege works. [61] Instead of using the traditional axle fixed to a frame, these devices are mounted on wheels that roll on a track parallel to the ground, with a counterweight that falls directly downward upon release, allowing for greater efficiency by increasing the proportion of energy transferred to the projectile. "[47] The traction trebuchet continued to serve as an anti-personnel weapon. Each weapon is built one tenth of the actual size. Because of its design, it allowed for greater throwing distance than the mangonel (comparable to that of a trebuchet).
De trebuchet bestaat uit een slingerarm met aan de lange kant als tweede draaipunt een slinger, die aan de ene kant vastzit aan de arm en aan de andere kant met een ring over een pin op het uiteinde van de slingerarm geschoven is.

[39] Chevedden argues that given the references to new and better trebuchets that by the 1120–30s, the counterweight trebuchet was being used in a variety of places by different peoples such as the crusader states, the Normans of Sicily and the Seljuks. Nadat de arm naar beneden is getakeld, wordt deze vastgezet. The mangonel could fire off more rocks than an onager.
