trebuchet counterweight ratio

While wood is easier to gather, it does consume more wood than reinforcements. No support or raft needed. Launches 25 feet. Whereas the payload was quite varied from 1 kg up to 59 kg (2 lbs to 130 lbs). Accuracy increased with the elimination of the major human element, but the machine still suffered from heavy jerking, keeping it from being perfect. . (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 120). The lead attached to the NOVA-built, fixed-weight trebuchet weighed a hefty six-and-one-half tons. The trebuchet relies on the principle that stored potential energy of the counterweight can be converted into kinetic energy of the payload, launching it into the air. . If the trebuchet is to be designed for maximum throwing distance, a question arises: At what point during its trajectory should the projectile be released? Good luck. A counterweight trebuchet is powered by a very heavy counterweight, acting on a lever arm. The counter-weight is usually much heavier than the projectile, typically by a ratio of 10 to 1 or more. Based on historical designs, it stands 18 metres (59 ft) tall and throws missiles typically 36 kg (80 lbs) up to 300 metres (980 ft). This machine appears to have been invented somewhere in the Mediterranean area in the late twelfth century, and to have spread outward very rapidly from its point of origin into norther Europe and western Islam. When the beam is quickly rotated by applying force to the opposite end of . Construction . A neat pile of stone ball trebuchet ammunition recovered from the moat at Pevensey Castle SOURCE: geography.org.uk via Michael Garlick (Copyright). Basic Circuits Kit: Conductors and Insulators. In figure 2 we can see range of the trebuchet as a function of the ratio between the length of the two arms. Chinese Siege Warfare: Mechanical Artillery & Siege Weapons of Antiquity An Illustrated History Internet: http://authors.historyforum.com/liang_jieming/chinesesiegewarfare>. This weapon is built on the idea of converting potential energy into kinetic energy to hurl a projectile over a large distance. A subreddit dedicated to the discussion of Conan Exiles, the open-world survival game set in the Conan the Barbarian universe! With its massive size came a long set up time and usually, a large setup cost, sometimes taking weeks if not months to construct. The Chinese invented the trebuchet in 300BC, the French were . By the way if the concept of the traction trebuchet is too odd for you, you might check out the following real life video of one and for those who want to rebuild one in the sandbox game besiege, there is also at least one video. weights from Dick's Sports for $6.99 a piece. I needed about 5 lbs so I used 2 plates and adapters and cable-tied them together. When assembled it has an internal capacity of 2600ccs. This website uses cookies to improve your experience while you navigate through the website. stones up to 275 meters, obliterating walls in their path[7]. Less tunable than HCW trebuchets at high ratios. The first of these, a "black box" model in which the mechanism for the Although, the counterweight-trebuchet was quite a feat in engineering, its influence on warfare was limited and the balance between offense and defense was not altered significantly. In the fall of 2005, he was pursuing a B.S. I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. Whereas the traction trebuchet had the force only applied for a short amount of time. The addition of a fixed counterweight was a major advancement in trebuchet technology. The trebuchet is the hallmark of medieval siege warfare and is synonymous. BRs of from 3:1 through 8:1 have been used, but at the low end you lose drop and at the high end you run into geometric problems and frame instability. Pictures. Medieval battlefields consisted mainly of sieges to fortified cities by some hostile force. One is the frame, one is the swing arm, and one is the set of moving parts. [12] J. Vaughan. It is assumed that it is a Chinese invention and made its way to Europe via the Arab world around the 9th century. Record the distance and time on a piece of paper, 8. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. because at 5:1, there was not enough power to lift the arm and the projectile A trebuchet works by using the energy of a falling (and hinged) counterweight to launch a projectile (the payload), using mechanical advantage to achieve a high launch speed. Yet, during operations it needed a large amount of manpower. The traction Trebuchet or Mangonel, which was adopted by the Byzantine empire some 100 years after their first recoded use in China, relying on man power to pull ropes and weights to thrown the projectile via the long swinging arm, a very time consuming and some what . There are many different approaches to building a trebuchet, and you can find many different guides and designs online and in books (see the Bibliography for one example). Finally, watch your trebuchet go. The catapult consisted of a solid base with a pivoting arm that would be pulled down and locked into place [1]. The whipper trebuchet is a modern take on trebuchets, geared toward throwing lighter objects long distance. To fix A trebuchet is made of a long beam attached by an axle suspended high above the ground by a stout frame and base. However, you may visit "Cookie Settings" to provide a controlled consent. with European battles from England to the balkans.

I made a "trigger" for the catapult out of two big shackles and a rod . I added a cover for the opening to keep kids from adding or removing things. Pick something with a high ratio of strength to weight. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 119; Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 271-272) It was the dominant form of artillery in Western warfare during the period of 1000 to 1300 AD. L2 is the distance between the pivot and the sling's attachment point (m). Here, we build a computational model of a basic trebuchet with the Multibody Dynamics Module and version 5.3 of the COMSOL Multiphysics software. Model Trebuchet can be made using Stripwood Technology techniques with card and 8mm x 8mm square timber. The traction trebuchet, which was a rather simple design were the force for firing was provided by men pulling down ropes. Figure 2 raises several questions about designing a trebuchet. Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. These improvements helped the trebuchet maintain dominance on the battlefield. The counterweight is raised and the trebuchet is cocked. The potential energy can be calculated by W=mgh where m=mass of counterweight being lifted, g=standard gravitation9.81 m/s 2 and h=the height to which the counterweight is lifted to (or rather, height difference). A trebuchet is a medieval stone-throwing war engine. Enjoy! One of these more modern designs is the . Scrohammer happily hurls these wee glass spheres of doom a surprising distance of 40 feet. The proper ratio for the throwing arm to the short arm is approximately 4 to 1, while the proper ratio for the counterweight to the projectile is approximately 100 to 1 [4].

It does not store any personal data. Enjoy! - Theory and mathematics of trebuchets, http://www.algobeautytreb.com/ 3). The technical storage or access that is used exclusively for statistical purposes. If you get stuck, you may need to consult a physics textbook, ask your physics teacher for help, or do your own internet search for "trebuchet physics." How much counterweight does a trebuchet need? Hill states about the Counterweight Trebuchet: The word trebuchet has been used for convenience to designate the rotating-beam siege machines, in the full knowledge that other terms were also used in the Middle Ages, and that the question of nomenclature remains unresolved. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 271) Counterweight trebuchets use gravity; potential energy is stored by slowly raising an extremely heavy box (typically filled with stones, sand, or lead) attached to the shorter end of the beam (typically on a hinged connection), and releasing it on command. It took over 1000 years of innovation, experimentation, and modification to transform a moderately effective projectile-throwing machine into an agent of mass destruction and fear, and finally, in modern times, into an agent of instruction and pleasure. A small-scale replica of War Wolf, a counterweight trebuchet that uses a boulder-holding sling at the end of a swinging arm. The machine is generally associated with hurling boulders at a castle wall to bring it down, but trebuchets have also been used to throw Greek fire and wreak all kinds of havoc. And the more complex counterweight Trebuchet were the force was provided by a counterweight, although it gives a rather simple impression, it was a quite complicated machine once you dive into the dynamics of it. Image from an illuminated manuscript depicting a Byzantine traction trebuchet at a siege of a citadel, 11th century. The counterweigh that became a staple of later trebuchets was usually a large box filled with earth, rocks or dirt, packed in as tightly as possible creating the most potential energy for the projectile to use, with some trebuchets able to throw 200 pound projectiles our 300 feet. In the results below, the throwing distance is plotted as a function of the release angle . Lets see if this holds true for the trebuchet model. It considers several models of varying complexity and finds a maximum range efficiency of 83% for a 100 pound counterweight, 1 pound projectile, a 5 foot long beam pivoted 1 foot from the point of attachment of the counterweight, and a 3.25 foot long . The counterweight is usually very heavy and provides the mechanical force to fire. Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. The curves shows the best ratio between the arms to be 2.3 : 1 no matter what the length of the counterweight arm within the range 0.321 - 0.5 m considered for my needs. We use technologies like cookies to store and/or access device information. L4 is the length of the rope suspending the counterweight (this distance is zero if the counterweight is fixed directly to the lever arm) (m). How much time do you have to build your trebuchet? Now, lets look at the range, there are no proper accounts according to Hill, but he assumes that 275 m (900 ft) should be correct. Every city occupied by Mongols in Central . In order to maximize their chance of winning, both the attackers and defenders employed trebuchets to help their cause. A golf ball projectile (1.62 oz) should fire best with 13.46 lbs of counterweight - and a 14 lb bowling ball should have 1862 lbs pulling on the other side of the arm to reach maximum distance. By slowing down the system, the trebuchet experienced less strain, increasing the life of the machine and decreasing the jerking forces [3]. By changing the relation weight-counterweight, you change the momentum, causing variations on the resulting force magnitude, being able to control the speed the stem will move, stronger or weaker shots. From this equation it is clear that the greater the gravitational potential energy of the counterweight therefore the greater the mass of the counterweight m1, and the greater the height to which it is raised/ falls through h, and the smaller the mass of the projectile, m2, the greater the initial velocity of the . The weight of the counterweight must be much greater than 10 times. Due to its low accuracy when targeting units it is ineffective against them. However, there have been occasions where trebuchets could reduce the wall to rubble in a few shots. On one end of the beam was a nest, sling or other element for holding the payload attached and on the other end several ropes for men pulling down the beam in order to provide enough force to propel the payload. Your arms will float up from your sides, as if lifted by an external force. Our model uses the following assumptions and physical dimensions: A schematic of the counterweight trebuchet model. Edward called upon his master castle builder, James of St. George to oversee to construction of a massive trebuchet that would be able to hurl 300 pound projectiles at the walls. Lets begin with the traction trebuchet, which is an older and simpler design. Trebuchet (My version) New axes and counterweight, new printable axes, and modified the counterweight. Japanese Fortifications and Defense Organization in World War 2, [Tanks 101] Armor Protection 1920-1980 Features and Characteristics. 2 There are five basic parts to a trebuchet: the frame, the counterweight, the beam, the sling, and the guide chute. Since they could be mounted on towers they would also outrange the attackers machine. Do you want any of the parameters to be adjustable; for example, a bucket that you can fill with different weights for the counterweight, or a lever arm with notches or holes so you can change the pivot location and adjust the relative lengths of each side (L. I hope you enjoyed this and would love to hear what you think, please leave me a comment and follow me on Instagram @chrisriley_ for more medieval history! The Chinese needed so much power for the trebuchet that they had up to 250 solders pulling on ropes to operate the machine [6]. For example, when I first shot my trebuchet I was using a 2.26kg payload and a 22.6kg counterweight. That's a weight ratio of 1:110. Furthermore, a mechanism for pulling down and fixating the long arm was added, which was usually a winch. The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network. Kaffa was a port city, so the disease soon spread across the Mediterranean and into European ports [3]. They work great over a huge range of mass ratios. Our hypothesis was not supported because the optimum arm ratio seemed to The ballista eventually gave way to the catapult [3]. The Hinged Counterweight Trebuchet (HCW) - a standard trebuchet. h is the initial height of the counterweight off the ground. Sling The sling is attached to the long end of the swing arm lever and holds the projectile that is to be thrown. It is assumed that the usage of heavy missile throwers was far greater in siege warfare in the Middle East than in Western Europe. The optimal trebuchet design is one that launches the payload the farthest horizontal distance. - History and details of the trebuchet, - Plans and directions for building a small trebuchet, http://www.io.com/~beckerdo/other/trebuchet.html. The sling is attached to the end of the long arm of the lever. 2 How long should the arm of a trebuchet be? How much weight can a trebuchet hold? For a small trebuchet, you may want to make them 1 foot (30 cm) long; for a larger trebuchet, they can be longer. 24 dimes should be placed in the counterweight. Rolling wheels prevent the crushing lurch. The counterweight should be 75 to 100 times the weight of the projectile. Defenders used trebuchets against siege towers and the enemy artillery, thus providing what we would call counter-battery fire nowadays. m2 is the mass of the payload (kg). Your email address will not be published. Large trebuchets of this type would typically feature a counterweight roughly ten times the weight of the projectile, which would put War Wolfs counterweight in the neighborhood of 1.5 tons! Enjoy! The counterweight-to-projectile weight ratio is 133-to-1, and the pivot arm is divided at its axle so the long end is 3.75 times the length of the short end. Create an account to follow your favorite communities and start taking part in conversations. Another error that could have occurred was the axle Its a cheaper version of the Counterweight Trebuchet (even cheaper than a Mangonel) with lower range, attack and hit points, in return for higher rate of fire, movement speed . of your trebuchet be? Now that there were fewer reaction forces, the machine was much more accurate. YAQUMW The Mini Counterweight Trebuchet with Wheel Europe Medieval Siege Chariot Catapult Weapons DIY 3D Wooden Puzzles Mechanical Model Kits for Adults STEM Projects Tabletop Toys Birthday Gift. 99. . Anyone who has played Age of Empires (this includes me, yes), will know exactly what a trebuchet is, and what it does. The trebuchet was preferred over a catapult due to its greater range capability and greater accuracy. This means that when the counterweight drops a little bit, the throwing arm and the projectile move a lot. It is sometimes called a counterweight trebuchet or counterpoise trebuchet, to distinguish it from an earlier weapon called the traction trebuchet, which employed pulling men working the mechanism. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. A large counterweight trebuchet. In 1304, on one of his campaigns to defeat Scotland, King Edward I besieged Stirling Castle and ordered his engineers to build a giant trebuchet. The hinge also helped to slow down the system when it reached the bottom. Repeat steps 4 8 for all ten settings. Ancient Weapon Inspires Student.. On the other hand, at the 3:1 ratio there was just the right balance (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 124), Note that trebuchets were not only used in the offense, quite on the contrary, there were also used effectively by defenders. The range of a trebuchet has always been important. What about moments of inertia, which are not labeled in Figure 3? I was able to use the collars from my weight set to hold the weights as they were slightly bigger than 1". One of the main difference to the traction trebuchet is the fact that a lot of force is applied on the beam, when the trebuchet is readied and held in position. Uninterrupted action by massed forces of large machines would surely have smashed masonry in time, but the conditions in which large numbers of such machines could be gathered and operated were relatively rare, and before the end of the twelfth century there is little evidence of artillery smashing the main masses of castles and walled cities. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 120), Another aspect in attacking walls was, that the quality of the stones was very important, because if the stone shatters on the wall, the damage is quite limited. The same counterweight but without supports. The projectile is inside a pouch hanging on a sling attached to the long end of a balancing beam. Namely, the Warwolf. Cocking . These cookies ensure basic functionalities and security features of the website, anonymously. A contemporary image of a trebuchet being loaded SOURCE: medievalists.net. A trebuchet (French trbuchet) is a siege engine used in the Middle Ages. The animation below shows the motion of the trebuchet as it is fired. Analytical cookies are used to understand how visitors interact with the website. A trebuchet is a type of catapult that uses a swinging arm to throw a projectile. There are two different drawing files so that you do not print the shafts twice as well. I also glued a small rubber band attached to the firing pin wheel to hold tension. Copyright 2002-2023 Science Buddies. An easier way to do it might be to find the Lagrangian of the system, KE-U, and find the equations of motion from that. Bernhard Kast ist Teilnehmer des Partnerprogramms von Amazon Europe S..r.l. A f2k trebuchet has an arm that rides on wheels, which roll forward on rails, while the weight bar running through the arm falls down in a vertical groove. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 121) Something that was not the case with the Counter-weight Trebuchet, so lets take a closer look at it. also different stuff as counterweight. General advice is that the optimal ratio is 133:1. There are many different factors that can affect the range of a trebuchet; for example, the mass of the counterweight or the length of the lever arm. As an Amazon Associate I earn from qualifying purchases. From what we know it seems that counter-weight trebuchets were used with heavier missiles. Below are some examples of different materials used as ballast. The graph displays the range of projectile as the y-axis and the ratio as the x-axis. Which is correct everyone do or everyone does? between leverage and speed of the arm to achieve the highest velocity. Trebuchets may be dead on the battlefield, but they are still very much alive in the hearts of students and hobbyists who take joy in discovering the workings of these amazing machines.
