2009. – 18 p. Catapult physics is basically the use of stored energy to hurl a projectile (the payload), without the use of an explosive. The three primary energy storage mechanisms are tension, torsion, and gravity. The catapult has proven to be a very effective weapon during ancient times, capable of inflicting great damage. The main types of catapults used were the...
Santa Fe, New Mexico: Desert Academy. – 19 p. The word trebuchet sounds like something you would find on a menu in a fancy French restaurant. But this medieval weapon of mass destruction was certainly not edible. Trebuchets were used to break through castle walls from about 850-1350 C.E. Dead livestock or giant rocks were the usual ammunition, but sometimes prisoners of war or...
Scientific edition. — Prague: Vědecko vydavatelské centrum «Sociosféra-CZ», 2013. — 212 p. — ISBN: 978-80-87786-52-9. This book deals with the problems of reconstructing ballistic performance, based on eclectic source material. Included are some concrete examples of the identification of the parameters of naval artillery. Also included is a database of naval artillery from the...
European journal of physics. 2005, 26, p. 561– 577. doi:10.1088/0143-0807/26/4/002 A siege engine is an ancient mechanical device designed to hurl rocks or other materials at or over the walls of a besieged fortress. It was usually constructed of wood such as oak, and often strapped with iron or rope for reinforcement. The engines of classical antiquity, such as the onager,...
(Mark Denny. Their arrows will darken the light of the sun. The evolution of ballistics as a science.) Baltimore, USA: The Johns Hopkins University Press, 2011. — 184 p. Ballistic science has been important to humans for as long as they have hunted or waged war, but it is only over the past 250 years that the scientific discipline of ballistics has matured from a craft art. A...
2015. — 10 p. Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. One of the most advanced siege engines used in the Middle Ages was the trebuchet, which used a large counterweight to store energy to launch a payload, or projectile. The horizontal distance the payload would travel...

Historia Mathematica 38, 2011. — р. 506–547 Mathematical ballistics in the United States until the First World War was largely dependent on the work of European authors such as Francesco Siacci of Italy. The war brought with it a call to the American mathematical community for participation in ballistics problems. The community responded by sending mathematicians to work at...
2008. – 32 p. Das absolute non-plus-ultra der mittelalterlichen Kriegsführung waren Festungen, in denen sich die Fürsten eines Landes verschanzen konnten. Meterdicke Mauern auf zumeist erhöht liegenden Plätzen, von denen Feinde schon aus der Ferne entdeckt und beschossen werden konnten und viel Stauraum für Nahrungsmittel und Soldaten. So ließ sich eine Belagerung bequem...
Crusader, 2015, Vol.(1), Is. 1. With a helping of simple mathematical models there was analyzed the ballistic information of the Arab arrow on medieval Arabic treatise "Arab archery". It is shown that there were no any errors on the text and the translation was correct, then, apparently, Arabian heavy arrow had specific design and can no to be in one quiver with the light...
Document in PDF-format. 2008. – 42 p. From engineering school class web sites. A trebuchet (French trébuchet) is a type of catapult that was used as a siege engine in the Middle Ages. It is sometimes called a counterweight trebuchet or counterpoise trebuchet, to distinguish it from an earlier weapon called the traction trebuchet, where men pulling ropes provided the power. The...

Document in PDF-format. 2006. – 65 p. The trebuchet, a medieval catapult driven by a falling, hinged counterweight, has been simulated to progressively more accurate approximations by successively more realistic physical models. The first of these, a "black box" model in which the mechanism for the transfer of the potential energy of the counter-weight to the kinetic energy of...
Document in PDF-format. – 22 p. The trebuchet was an immense counterpoise siege engine that became the artillery weapon of choice throughout the middle ages. This project’s aim was to model the mechanics of one such engine by use of an Euler method as opposed to the more common Lagrangian form. While the mechanics of second complexity level have been modelled quite successfully...
Oberwolfach Reports, European Mathematical Society, 2013, 10 (1). Throughout the 18th and 19th centuries, various methods were used to integrate the ballistic differential equation and to calculate firing tables for the needs of artillery. Mathematicians, military engineers and artillerymen, although belonging to different milieus and different countries, collaborated and...
2009. — 24 p. A trebuchet is a battle machine used in the middle ages to throw heavy payloads at enemies. The payload could be thrown a far distance and do considerable damage, either by smashing down walls or striking the enemy while inside their stronghold.
