One of the most famous examples of a trebuchet is that which was used at the siege of Sterling Castle in 1304. Hence, it really depends how one defines as handling and/or operating. For any other use, please contact Science Buddies. The Counterweight Trebuchet was more complex, instead of men pulling down the beam, another axle with a counterweight was fixed on the end of the beam. VirtualTrebuchet is a web based trebuchet simulator that will allow you to quickly evaluate different trebuchet configurations. Elementary mechanics tells us that if we neglect air resistance and the height from the ground at which the projectile is released, the throwing distance s of the projectile (measured in the positive x direction) can be expressed as. The power delivered to a wall from a device like this could be incredibly devastating. [Weapons 101] Trebuchet - How they work - Traction & Counterweight Trebuchets Medieval Equipment Military History Visualized 190K views 6 years ago How to Operate a Mini Trebuchet Joe Staggs. Whatever you decide you want to launch with your trebuchet, your counterweight should be from 100 to 133 times the weight of your projectile. Science Buddies Staff. These improvements helped the trebuchet maintain dominance on the battlefield. of the sides twice. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 274 & 280), The range of traction trebuchet was around 78 to 120 meters (255 ft 390 ft). trebuchet. 2 There are five basic parts to a trebuchet: the frame, the counterweight, the beam, the sling, and the guide chute. 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." From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). Trebuchet (My version) New axes and counterweight, new printable axes, and modified the counterweight. . Enjoy! These references will be useful for learning about the physics of trebuchets. The sling is attached to the end of the long arm of the lever. L1 is the distance between the pivot and the counterweight's attachment point in meters (m). The technical storage or access that is used exclusively for anonymous statistical purposes. Hill states about the Counterweight Trebuchet: Create an account to follow your favorite communities and start taking part in conversations. Catapulting Science Into Fun.. I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. So it's easier now to fill it with anything you want. Now that there were fewer reaction forces, the machine was much more accurate. Image by Ron L. Toms. Licensed under CC BY 3.0, via Wikimedia Commons. Youll need to cut 8 pieces: Two long base pieces. What is the best ratio for a trebuchet? In addition to building prototypes of a trebuchet, you can also use physics calculations or even a computer simulation to help you design it to have the best range. But the usual weight was probably more around 45 to 90 kg (100 to 200 lbs). The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. 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. This weapon is built on the idea of converting potential energy into kinetic energy to hurl a projectile over a large distance. You can vary the weight on the back easily by putting more or fewer rocks inside. Internet: http://www.trebuchet.com, [Oct. 11, 2006]. If you are trebbing and run out of wood or iron, you can keep repairing the trebuchet up to 2500/5000 health with only one of the mats! The most efficient way for any counterweight to respond to the force of gravity is by falling in . Is there anything heavier than a 100 stack of stone (13.00 "weight") that can be used as a counter? Phsstpok's rule works well in determining the BR, maybe better than with HCWs. What about moments of inertia, which are not labeled in Figure 3? Never "dry fire" the trebuchet - always load a projectile to balance the firing mechanism. A 3D model of Counterweight used in Horizontal Striling Engine, rebuilt this Trebuchet design in Rhino, made it easier to 3d print. To begin, enter the parameters of your trebuchet in the input boxes. Bernhard Kast is a participant in the Amazon.com.ca, Inc. Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.ca. Next, grab the handles and pivot to the angle you want it to fire at, then press the lever to release the brutal weapon. The ballista worked well against troops and cavalry, but had no effect upon walls and structures [2]. Several museums around the world have also built their own, with Middelaldercenteret in Nykbing Falster in Denmark as one of the first modern examples of counterweight trebuchet (Hansen, 1989). The counterweight is cast concrete, 8 inches wide, 15 inch radius from the pivot hole to the curve of the concrete, 108 pounds total. connection. Figure 1, below, shows a modern reconstruction of a trebuchet. The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. 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. Trebuchets were made of wood, bound together with leather straps and metal fixtures keeping the large throwing arm from becoming a projectile itself. . (2020, June 23). fit. This massive weapon was eventually capable of throwing massive boulders over 250 meters, but it did not start that way.

Whereas the payload was quite varied from 1 kg up to 59 kg (2 lbs to 130 lbs). The construction and operation of the counterweight-trebuchet was the province of specialist engineers, who were not always available, and it was ponderous to transport. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123) Please note: This post contains amazon affiliate links. The Hinged Counterweight Trebuchet (HCW) - a standard trebuchet. Simple as it seems, the trebuchet is a complicated dynamical system. A trebuchet is made of a long beam attached by an axle suspended high above the ground by a stout frame and base. stones up to 275 meters, obliterating walls in their path[7]. Once you have derived an equation for the range of a trebuchet based on the physical parameters above, can you come up with any design guidelines or rules of thumb for designing a trebuchet with the best possible range? However, counterweight trebuchet was almost never used in ancient China, and traction trebuchet has been the mainstream for thousands of years. 2). Now you will build the trebuchet's arm. What size planking do I need to make a trebuchet? As an Amazon Associate I earn from qualifying purchases. I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. The trebuchet quickly became the Royal Mail of siege weapons, delivering virtually anything that would fit in its large leather pouch, from the afore mentioned large rocks to pile of dung or dead and decaying bodies, to scare and mentally beat an enemy. The Traction Trebuchet is a siege weapon in Age of Empires IV that is unique to the Mongols. A trebuchet (French trbuchet) is a siege engine used in the Middle Ages. The Yet, Hill notes that without the addition of a long sling, there was no possible combination that would have made it feasible weapon. the design and manufacturing of trebuchets changed little, once the counterweight had been added to the design, the overall look and effectiveness of the weapon varied little between time periods and the people using them. This happens when one end of the sling slips off the tip of the swinging arm. [5] Wikipedia. The maximum throwing distance is obtained if the projectile is released at 38. How much counterweight does a trebuchet need? The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1. This counterweight was affixed to the end of the shorter arm and, without the need for ropes and people to pull the machine, space was available for lengthening the sling, which allowed the projectile to go even farther [3]. (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. Anyone who has played Age of Empires (this includes me, yes), will know exactly what a trebuchet is, and what it does. could be altered, the idea behind the trebuchet was that the counterweight could bring the projectile full circle for a greater arc and therefore a greater throwing distance and force. You can print every part with standard settings. Our team of volunteer scientists can help. All weapons have their pros and cons with the trebuchet having its fair share of both. Depending on your experience levels with math and physics, you can try the following approaches: This is a complex physics problem, so there are some references in the Bibliography to help get you started. I was able to use the collars from my weight set to hold the weights as they were slightly bigger than 1". Apparently, the French name Loup de Guerre (wolf of war) proved more than a mouthful for the English soldiers, so it was condensed into Ludgar. Set out a meter tape starting from the front of the base and lay on (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 121) The counterweight was filled with stone, sand, lead or other heavy material. This makes sense intuitively since range is a key factor when staging an attack on an enemy. The animation below shows the motion of the trebuchet as it is fired. https://www.thingiverse.com/thing:3627759. you can make your own counterweight (i used old 1.25 lb plates) the peg for the counterweight is just under 1.1 in. The cookie is used to store the user consent for the cookies in the category "Analytics". Proudly created with Wix.com, Weapons That Changed The World: The Counterweight Trebuchet, It is rumoured that Edward was so keen on trying out his new toy that he ordered the recently surrendered Scots back into the castle, quoted to have said ", You do not deserve any grace, but must surrender to my will" and. The velocity, distance, and trajectory are not only dependant on the ratio of projectile weight to counterweight but also the sling length, cog length and angles, and beam length and angles and counterweight motion. The traction trebuchet, which was a rather simple design were the force for firing was provided by men pulling down ropes. Many teachers also use trebuchets to teach the fundamentals of physics to their students, and hobbyists build huge devices to enter in competitions that require the trebuchets to launch a wide variety of objects including pumpkins, pianos, cars, coffins, and even the builders themselves [8]! Most of these items were meant not to destroy walls, but to humiliate the enemy, taint their water supplies, and spread death and disease. https://youtu.be/5RZazivVX7k [3] If you want to launch items of various weights, you can set up your trebuchet with a bucket or bag to hold and adjust the counterweight. As with the longbow, the time of the trebuchet was cut short by the introduction of both handheld fire arms and large wall destroying cannons, ushering in a new age of death and destruction. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); The medieval battlefield was dominated by large artillery weapons, and among these the trebuchet was king. A powerful catapult had the capability to launch a 27-kilogram stone, but had little effect on walls or fortified buildings located over 160 meters away [3]. Used to hurl giant stones or boulders (see image below) directly at the walls of castles or fortifications or, simply to throw disease ridden bodies or other unpleasantries over the walls, to sap moral and infect the inhabitants waiting inside. The ratio of the mass of the counterweight to the mass of the payload, expressed as CW:P. A typical MR is 100:1. The results from this were lackluster. pushing it forward, or pushing it backwards. Although they have not been used in any important military capacity in hundreds of years, trebuchets are awesome pieces of engineering that still create excitement in todays society. A trebuchet is a machine where making a change in any one area has an effect on the final result: the fling. Lets begin with the traction trebuchet, which is an older and simpler design. Yet, during operations it needed a large amount of manpower. The counter-weight is usually much heavier than the projectile, typically by a ratio of 10 to 1 or more. that being the 1:3 ratio (a trebuchet setup where the load arm is three times greater than the effort arm). Chinese Siege Warfare: Mechanical Artillery & Siege Weapons of Antiquity An Illustrated History Internet: http://authors.historyforum.com/liang_jieming/chinesesiegewarfare>. recommend you keep the infill high for the pegs, and decently high for the legs, arm, and base. Gravity. (2006, Oct. 12) Military Technology., [8] R. Meyer, Column One; How Far Can a Piano Fly?, [10] D. Moe. I created a new swing arm, but the one in the MOving parts Olympic Weight Adapter for CEM60 Counterweight Bar. This is probably the most exciting part of investigating how trebuchets work: actually building one! Mc=30, Mp=0.5, Sa= -46, and Lc=0.321 or 0.5. In either case, can you make your analysis more realistic by accounting for things like friction and air resistance? 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. Some of this energy (not all) will be transformed to kinetic energy of the projectile. By providing your email address, you consent to receive emails from COMSOL AB and its affiliates about the COMSOL Blog, and agree that COMSOL may process your information according to its Privacy Policy. Gurstelle once made a large trebuchet with a 500-pound (226-kilogram) counterweight that was still only powerful enough to launch a small cantaloupe. But John France notes: 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). Counterweight trebuchet was invented by Muslims, and then the Mongols introduced it into the Chinese battlefield and used it to capture China's Xiangyang, that is, the special unit of the Mongolian campaign. Figure 1, below, shows a modern reconstruction of a trebuchet. Repeat steps 4 8 for all ten settings. You manually load it by placing the ammo on the trebuchet in the inventory menu, then place rocks in the counterweight section to determine how far the projectile will fly. The force that the catapult needed to launch the projectile came from the manipulation of twisted ropes [3]. 2 How long should the arm of a trebuchet be? Adult supervision is required when building and operating a trebuchet. The main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. See gravitational potential energy. another potential negative for the trebuchet is its immovability. What are various methods available for deploying a Windows application? The person who was timing started the watch when the projectile was On the other hand, at the 3:1 ratio there was just the right balance In use for almost 1000 years, the medieval version of the Chinese trebuchet transformed the battlefield thus changing the world forever. Can you pick these parameters based on hand calculations or computer simulations (above), or based on design information you found through your own research? 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. If you search online, there are many different plans and designs for building a trebuchet. An Introduction to Gear Modeling in COMSOL Multiphysics, The Motions and Mechanics of a Truck-Mounted Crane, Multiscale Modeling in High-Frequency Electromagnetics, All of the components are assumed rigid (including the sling), All hinged joints are assumed frictionless, The projectile is prevented from falling through the ground using a penalty stiffness, The counterweight hangs from a beam of length, The swinging arm is 6 meters in total length with. How heavy should the counterweight and the payload be? The proper ratio for the counterweight to the projectile is about one hundred to one while the ratio of the throwing arm to the short arm is about four to . I added a cover for the opening to keep kids from adding or removing things. be 3:1 and not 5:1. What real-world things (like air resistance, or how exactly the payload is released from the sling) were difficult to account for in your calculations or simulations? 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? Yet, one would assume that proper calculations or laborious trial and errors of various variations could produce an effective counterweight-trebuchet. By clicking Accept All, you consent to the use of ALL the cookies. One of the most important components of the trebuchet is the sling, which greatly increases the range of the weapon by simply extending the length of the throwing arm [5]. For centuries, the trebuchet was the most powerful war machine in the world. The variables in Figure 3 are as follows: How can you use these variables to calculate the range of a trebuchet? Is there anything heavier than a 100 stack of stone (13.00 "weight") that can be used as a counter? Science Buddies Staff. Looking at their advantages and disadvantages, traction trebuchets were probably used for throwing light missiles, whereas the counter-weight trebuchets used for heavy stones. There are other accounts for other sieges giving a value of about 250 kg (560 lbs). The weight of the counterweight must be much greater than 10 times. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. Since the middle ages, however, engineers have developed newer, more efficient styles of the trebuchet. Hurl those stones. If you are interested in learning more about multibody dynamics modeling, check out these additional blog posts: Wondering why War Wolf was also called Ludgar? L2 is the distance between the pivot and the sling's attachment point (m). One of the worst cases of such early chemical warfare came in the 14th century when Mongols fired corpses that contained the Black Death into the city of Kaffa. The cookies is used to store the user consent for the cookies in the category "Necessary". Read the relevant section(s) below for ideas on how to get started on your project. The actual size of War Wolf is unknown but, we do know that once dissembled, the parts fit into over 30 wagons and modern estimates have the massive structure at over 300 feet tall. The trebuchet is a large siege weapon that you might recognize from movies set in the Middle Ages or fantasy worlds. The projectile is inside a pouch hanging on a sling attached to the long end of a balancing beam. This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet, SummaryI rebuilt this Trebuchet design in Rhino, made it easier to 3d print. It is assumed that it is a Chinese invention and made its way to Europe via the Arab world around the 9th century. The Wikipedia page on trebuchets links to a PDF paper which discusses exactly this question. 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 inconstant tool. The FAKA is very efficient for its frame height and arm length as well. A trebuchet is a type of catapult that uses a swinging arm to throw a projectile. Repeat steps 4 7 to get two more trials on this arm ratio setting, 9. One nonfictional and historically notable trebuchet is War Wolf (known to the English soldiers at the time as Ludgar). [13] History Forum. The quantity s is shown along the projectile trajectory, and it represents the throwing distance that would follow from releasing the projectile at a certain point on this trajectory. 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 . https://youtu.be/5yMxEXfg85k Credit to Ben Goodwin for helping create this Trebuchet. 24 dimes should be placed in the counterweight. Military History Visualized subscribestar, Military History Visualized Merchandise. m2 is the mass of the payload (kg). Related. 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 . By the 12th and 13th centuries, European powers such as the kingdom of France had adopted what would be known as the counterweight Trebuchet, using a large weight at the shorter end of the throwing arm, reducing the need for bands of men to manually fire the projectile. In movies and computer games Trebuchets are often shown as weapons that can destroy city walls and towers easily. But opting out of some of these cookies may affect your browsing experience. A modern scale model of War Wolf showing the large wheels which men would run in to pull the large arm down ready for loading SOURCE: Ron L. Toms Via Trebuchet.com. The horizontal distance the payload would travel is called the trebuchet's range. So a trebuchet with a long arm and a heavy counter weight will throw a projectile further then a trebuchet with a short arm and a light counter weight. Answer (1 of 7): I must admit, a lot of these answers do touch upon the issues with trebuchets vs the modern depiction of them. We tried 100x Ironstone ore (10.00 "weight") and Heavy Armor, but none of it seemed to work better. Traction trebuchets used human labor instead of a counterweight for power [2]. 1) and the catapult [1]. listed if standards is not an option). The floating arm trebuchet uses a counterweight held on top of a tall drop channel to transfer potential energy into kinetic energy. Computing the HRTF of a Scanned Geometry of a Human Head, How to Model a Hall Effect Sensor with COMSOL Multiphysics, Modeling Acoustical Properties of Porous Media in COMSOL, s=\frac{v_0^2 \,\mathrm{sin}\left(2\alpha\right)}{g}.

These cookies track visitors across websites and collect information to provide customized ads. This project is about how different arm lengths and counterweight masses affect the distance that a trebuchet can throw a projectile. Ideally a ratio of around 100/1 ballast to projectile weight should be used, this results in . Lets see if this holds true for the trebuchet model. The further between . But the question of the exact provenance of the invention, whether in Europe or in Islam, is not resolved. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 275-276). A trebuchet exists as a medieval rock throwing machine, but quite different to a catapult. The first of these, a "black box" model in which the mechanism for the 99. . The trebuchet is the hallmark of medieval siege warfare and is synonymous. More About scull_mech This is a general description of how to create a floating arm (f2k) trebuchet. Which is correct everyone do or everyone does? holes for our first axle and had to change the axle when the first one that we Not consenting or withdrawing consent, may adversely affect certain features and functions. I would recommend bring at least 2-300 . All rights reserved. A counterweight trebuchet is powered by a very heavy counterweight, acting on a lever arm. What tools and safety equipment do you have access to? Why do trebuchets have wheels? With the sling in place, the crew just has to change the angle of the sling and the projectile will be aimed at its new target. In addition to unequal weights, the trebuchet uses leverage. No support or raft needed. Figure 2, below, shows a diagram of a trebuchet with the main parts labeled. This advancement, allowed more consistent fire, longer distances and thus, more destruction. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet, I rebuilt this Trebuchet design in Rhino, made it easier to 3d print. It was also easier to transport and had a higher rate of fire. These super weapons are the result of over two millennia of trial and error that began with the development of the trebuchet. Thanks. John France notes: The main advantages of the traction trebuchet were that it was faster and cheaper to build and needed no specialists, unlike the counterweight trebuchet. Sling The sling is attached to the long end of the swing arm lever and holds the projectile that is to be thrown. However, since the trebuchet is much easier to aim at a large stationary target than small mobile targets, it was usually much more effective for the side laying siege[1]. - user21033 Mar 24, 2013 at 16:03 Add a comment 0 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. It is a hinged counterweight trebuchet in which the counterweight hanger is placed on the top of the arm and the arm is pointed in the forward throwing direction when cocked. PLEASE NOTE: Posts and pages contain amazon affiliate links. One of the last recoded uses being in 1521 at siege of the Aztec capital Tenochtitln by the Conquistador Hernn Corts, where gunpowder was extremely limited which forced the Spanish forces to use more 'primitive' techniques. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 276-277) Another major factor was the use of a long sling, which was not unique to the Counterweight trebuchet, but more on this later. Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. Now, the number of ropes in the illustration is not correct, they were usually around 40 to 125 ropes and pulled by 40 to 250. Regardless of wether this specific event took place, bodies or at least body parts were used to ruin the days of besieged peoples, leading sometimes to mass outbreaks of diseases, wiping out entire cities without the attackers ever storming the walls.
