The projectile undergoes a swinging motion and is released at some suitable position along its trajectory. What tools and safety equipment do you have access to? The Hinged Counterweight Trebuchet (HCW) - a standard trebuchet. The range of a trebuchet has always been important. However, the king would not have it, as he was eager to try out his new trebuchet. There is more than one way to tackle the problem. The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1.

What experience do you need to become a teacher? These cookies will be stored in your browser only with your consent. Sling The sling is attached to the long end of the swing arm lever and holds the projectile that is to be thrown. How long should the arm of a trebuchet be? One of the most famous examples of a trebuchet is that which was used at the siege of Sterling Castle in 1304. (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. The floating arm trebuchet uses a counterweight held on top of a tall drop channel to transfer potential energy into kinetic energy. As an Amazon Associate I earn from qualifying purchases. 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. 2). Lets see if this holds true for the trebuchet model. Your email address will not be published. No support or raft needed. 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 . 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. 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. This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. 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). Please enter a search term in the text box. These references will be useful for learning about the physics of trebuchets. The lead attached to the NOVA-built, fixed-weight trebuchet weighed a hefty six-and-one-half tons. Pictures. Your email address will not be published. The hinge greatly increased the efficiency of the motion involving the counterweight, causing more power to be delivered to the projectile. Licensed under CC BY 3.0, via Wikimedia Commons. Anyone who has played Age of Empires (this includes me, yes), will know exactly what a trebuchet is, and what it does. Also, adding wheels could further stabilize the siege machine and enhance the throwing distance of the projectile. The poor prospects of surviving an assault from War Wolf prompted the Scottish garrison inside the castle to offer their surrender. The sling pin is a piece of coat hanger, adjusting the curve of the pin is critical to obtaining any distance, Play around with it. 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 Trebuchet and Siege Warfare During the Middle Ages, the construction of fortified cities led to a new type of military campaign the siege. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 284) Thus, counterweight trebuchets with hard stones were probably used against fortifications, whereas traction trebuchets were used to attack softer targets like buildings. The technical storage or access that is used exclusively for anonymous statistical purposes. 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. wind could have caused us errors by blowing our projectile off to one side, Feed some string through the hole and tie the bucket in place. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. The simplest trebuchet is basically a throwing arm pivoted on a fulcrum. another potential negative for the trebuchet is its immovability. So, basically, not. Copyright 2002-2023 Science Buddies. The complete trebuchet mechanical system is truly a dynamic one. A heavy counterweight hangs on the short end of the beam. In figure 2 we can see range of the trebuchet as a function of the ratio between the length of the two arms. explanatory. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. 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. Pieces: 166+ pcs Assembly Time: 4h Assembled Size: 14.9x7.8x8.2 in Recommended Age: 14+ Material Description 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.

The power delivered to a wall from a device like this could be incredibly devastating. drill the holes for the smaller axle in the first place. Will allow to have fun in areas such as home and office, for children and adults. Now, since we covered that part, lets get started. To throw the payload as far as possible, how long should the beam be? In addition to unequal weights, the trebuchet uses leverage. Less tunable than HCW trebuchets at high ratios. Enjoy! Enjoy! The trebuchet is an ancient siege engine used for throwing large rocks. Another error Necessary cookies are absolutely essential for the website to function properly. 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]. SOURCE: Skylitzes chronicle, Madrid, National library via medeivalists.net. When the beam is quickly rotated by applying force to the opposite end of . and still have enough energy to throw the projectile at a high velocity.

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. Do you need to build a miniature trebuchet that fits on a tabletop? forcing the projectile out of the leather bag and onto the target. Larger trebuchets would have large 'hamster' style wheels on the side of them, allowing men to run inside them to winch down the large arm where the projectile would be added, a pin would then be removed throwing the large arm upwards. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 274), According to Donald Hill the most detailed account for traction trebuchets are from Chinese sources and he mentions the following numbers that are also similar to Arabic sources, but take them with a large grain of salt: (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 274) The trebuchet is the hallmark of medieval siege warfare and is synonymous. Enjoy! That's a weight ratio of 1:110. Military History Visualized Offical Homepage for the YouTube Channel. When the counterweight is raised up, it has lots of gravitational potential energy. How closely do they match? 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. A trebuchet has a lever arm with a large, heavy counterweight on one end and a smaller projectile on the other end. The projectile is inside a pouch hanging on a sling attached to the long end of a balancing beam. The counterweight is usually very heavy and provides the mechanical force to fire. A trebuchet exists as a medieval rock throwing machine, but quite different to a catapult. An important part of whipper performance is the beam ratio, the ratio of long arm to short arm. 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. A large counterweight trebuchet. 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. (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. Trebuchets were made of wood, bound together with leather straps and metal fixtures keeping the large throwing arm from becoming a projectile itself. Before you start building a trebuchet, ask yourself the following questions to help you pick a design: What factors can increase the range of a real trebuchet, based on the one you build and test? We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. the side of the tape the projectile landed, we just looked at the meter tape and Building a large gallery for him and his entourage to watch the destruction from, he had the trebuchet fired and the walls quickly turned to rubble showing just how terrifying and Ferocious both the king and his massive weapon was. 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. and don't have more than a 1:45 ratio of object mass to counterweight mass. Simple as it seems, the trebuchet is a complicated dynamical system. But opting out of some of these cookies may affect your browsing experience. We launched pumpkins and bowling balls around 10-15 lbs at distances of 300+ feet. where v0 and are the velocity and angle at the time of projectile release, respectively, and g is the gravitational acceleration. The fixed counterweight eventually gave way to a hinged counterweight (Fig. Powered by STLFinder search engine. [7] Encyclopedia Britannica. Namely, the Warwolf. General advice is that the optimal ratio is 133:1. 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. Where should the pivot point be on the beam? VirtualTrebuchet is a web based trebuchet simulator that will allow you to quickly evaluate different trebuchet configurations. Try for yourself by downloading the model file from our Application Gallery. It was also easier to transport and had a higher rate of fire. Required fields are marked *. This book also contains some useful designs and building tips: Autodesk Inventor software is available as a free download for students from: If you like this project, you might enjoy exploring these related careers: You can find this page online at: https://www.sciencebuddies.org/science-fair-projects/project-ideas/ApMech_p013/mechanical-engineering/effect-of-trebuchet-arm-length-or-counterweight-mass-on-projectile-distance. Science Buddies Staff. Here, we build a computational model of a basic trebuchet with the Multibody Dynamics Module and version 5.3 of the COMSOL Multiphysics software. This is probably the most exciting part of investigating how trebuchets work: actually building one! Whereas the traction trebuchet had the force only applied for a short amount of time. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 120). [11] Ripcords Trebuchet Stuff. Thus, sometimes stones were transported a long way: Consenting to these technologies will allow us to process data such as browsing behavior or unique IDs on this site. 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 trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. Launches 25 feet. For a small trebuchet, you may want to make them 1 foot (30 cm) long; for a larger trebuchet, they can be longer. While this is happening, the wheel is moved backwards by the torque acting on the arm from the counterweight. A trebuchet is made of a long beam attached by an axle suspended high above the ground by a stout frame and base. However, as I said earlier, a 1:4 ratio arm isn't going to throw anything very far on its own. The counterweight trebuchet appeared in both Christian and Muslim lands around the Mediterranean in the 12th century. On the other hand, at the 3:1 ratio there was just the right balance 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 main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. I added a cover for the opening to keep kids from adding or removing things. Medieval trebuchets took many master craftsmen money and material to build, allowing defending forces to build their own countermeasures or, simply escape the deadly range and power of the trebuchet. 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. Now, lets examine what happens if we modify the length of the sling by 10% using a parametric sweep. 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. of your trebuchet be? To begin, enter the parameters of your trebuchet in the input boxes. As you can see in my sons video, above, the projectile never swings backward beyond its starting point, reducing the danger to bystanders behind the trebuchet. Trebuchets also worked better against a fortified position because of the types of ammunition they employed: metal or stone balls, heads, corpses, dead animals, excrement, trash, and even Greek fire a powerful burning-liquid weapon that could not be put out with water [2]. One fascinating rumoured example of bodies being used comes from the siege of Kaffa, where in 1347, the plague ridden Mongols outside of the city started to fling over their dead and dying soldiers into the city in a hope that the smell alone, rumoured to be particular foul, would destroy the moral of the defenders calling for their surrender. Some errors that we had in measuring could have happened because we laid the meter tape on the ground in a stationary position and no matter how far to What size planking do I need to make a trebuchet? In order to change the trajectory of the projectile, the operators had the option of either angling the whole machine or changing the angle of the crossbar [1]. In order to maximize their chance of winning, both the attackers and defenders employed trebuchets to help their cause. 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 . John France notes: [Siege of Acre (1189-1191)]. remember to print the side part twice. Is a full counter weight of 100 stone stacks the max power/range of the Treb? released and stopped it when it landed, which could have been 60 M away. For an outdoor trebuchet, you can use 2 x 4-inch (5 x 10 cm) planking. Its currently set up for a 100:1 counterweight to projectile mass ratio, with 200lbs of counterweight. with European battles from England to the balkans. 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! Now, one drawback of the Traction Trebuchet was that the men operating the machines had a varying pull on the ropes, thus the firing range was likely changed from shot to shot even without accounting for exhaustion. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 274 & 280). In other words, as long as the release angle is roughly correct, the trebuchet will function as intended. However, you may visit "Cookie Settings" to provide a controlled consent. 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. 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. 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. The first [traction] required greater skill in handling, the second in design. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 279) One of the final improvements to reach the trebuchet was the propped counterweight [3]. 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). Thus, although it was a rather simple machine, the handling required quite some training and coordination. Trebuchet (My version) New axes and counterweight, new printable axes, and modified the counterweight. 6 What are the advantages of a floating arm trebuchet? Ancient Weapon Inspires Student.. The results from this were lackluster. Every city occupied by Mongols in Central . https://www.thingiverse.com/xbxbxb123/designs, For the Trebuchet, I work on the counterweight and the fire arm. The technical storage or access is required to create user profiles to send advertising, or to track the user on a website or across several websites for similar marketing purposes. Set out a meter tape starting from the front of the base and lay on that being the 1:3 ratio (a trebuchet setup where the load arm is three times greater than the effort arm). When the trebuchet is fired, the counterweight drops, and the potential energy of the system is converted into a combination of kinetic and potential energy. These cookies ensure basic functionalities and security features of the website, anonymously. Not only does the sling add firing distance to the trebuchet, it gives the crew manning the trebuchet the ability to aim. It does not store any personal data. Will you need help from an adult to use tools like a power drill or saw? Mc=30, Mp=0.5, Sa= -46, and Lc=0.321 or 0.5. Next, press the "Simulate" button located under the inputs. Before the addition of the sling, the crew had to move the entire trebuchet to change the direction of the trajectory. Our hypothesis was not supported because the optimum arm ratio seemed to These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Gravity. Drill a small hole into the back end of the swing arm about 1 inch (2.5 cm) from the end. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123). The earliest trebuchets were traction trebuchets [which] were invented in China in the 5th 3rd centuries B.C.E. [6]. A trebuchet is a type of catapult that uses a swinging arm to throw a projectile. Trebuchet A siege engine for hurling heavy loads BuildingItem Health 5000 Container Size 15 Weight 50.00 Knowledge Engineer ID 89813 Engineer Recipe ID 89801 Level 25 Cost 3 Requires Teaches Siege Foundation A foundation for building siege equipment Crafted at Any carpenter's bench Trebuchet Base A rotating base for a trebuchet [4] Trebuchet.com. Counterweight powered trebuchet where the counterweight is directly attached to the short arm. Rolling wheels prevent the crushing lurch. While wood is easier to gather, it does consume more wood than reinforcements. The easiest counterweight to attach is a small bucket. The Floating Everything Trebuchet (FET) - a poor man's FAT, without the vertical guides. Furthermore, a mechanism for pulling down and fixating the long arm was added, which was usually a winch. Some of this energy (not all) will be transformed to kinetic energy of the projectile. Hence, it really depends how one defines as handling and/or operating. 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. However, counterweight trebuchet was almost never used in ancient China, and traction trebuchet has been the mainstream for thousands of years. 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! The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. 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]. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. also different stuff as counterweight. 2 stacks of fire arrows are the same. 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 ballista worked well against troops and cavalry, but had no effect upon walls and structures [2]. Also, the newfound stability meant that the trebuchet did not have to be repositioned after every shot, so firing time improved to about twice per hour [6]. . (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 274; France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 119) What should the various dimensions and parameters (lever arm length, counterweight mass, etc.) Counterweight is filled with spare change. Do you have a large outdoor area to test a big one? many timing errors. L1 is the distance between the pivot and the counterweight's attachment point in meters (m). 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) This cookie is set by GDPR Cookie Consent plugin. Yet, Hill notes that without the addition of a long sling, there was no possible combination that would have made it feasible weapon. 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). The horizontal distance the payload would travel is called the trebuchet's range. it will likely jam, but the counterweight or the arm might also strike the frame. It is assumed that the usage of heavy missile throwers was far greater in siege warfare in the Middle East than in Western Europe. of the sides twice.

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. 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. 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. There are basically two types of trebuchets, the traction trebuchet, which was operated by men pulling ropes and the counterweight trebuchet, which provided the necessary force by using a counterweight. To summarize, there were two main types of trebuchet that were used during the middle Ages. The trebuchet had a problem of sagging to one side, so I made some guy wires to hold everything relatively straight. Bernhard Kast ist Teilnehmer des Partnerprogramms von Amazon Europe S..r.l. Whereas the payload was quite varied from 1 kg up to 59 kg (2 lbs to 130 lbs). 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. 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. (2006, Oct. 12) Military Technology., [8] R. Meyer, Column One; How Far Can a Piano Fly?, [10] D. Moe. From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). 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? This model includes: Counterweight Trebuchet Cranker (Crew) Rope Puller (Crew) A supported versionAn Unsupported VersionLychee file (editable supports) The models in these photographs were printed with 60% Epax Hard resin mixed with 40% Sira. When assembled it has an internal capacity of 2600ccs. The main advantages of the counterweight trebuchet were its ability to fire larger stones and require less manpower during operations.
