Furthermore, a mechanism for pulling down and fixating the long arm was added, which was usually a winch. 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 . As the projectile is swung around by the swinging arm, it describes a nontrivial motion of varying velocity. VirtualTrebuchet is a web based trebuchet simulator that will allow you to quickly evaluate different trebuchet configurations. 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. Required fields are marked *. What is your budget, and what materials do you have access to? For any other use, please contact Science Buddies. Repeat steps 4 8 for all ten settings. Powered by STLFinder search engine. Machines Power Source. Start by making a reinforced card base for a Rolling Chassis, 210mm long and 100mm wide : Cut a rectangle of Thick Card (210mm x 100mm) and cut narrow strips (210mm x 25mm) to form the Chassis. 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. Another error that could have occurred was the axle The Traction Trebuchet is a siege weapon in Age of Empires IV that is unique to the Mongols. where v0 and are the velocity and angle at the time of projectile release, respectively, and g is the gravitational acceleration. Bernhard Kast is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com. The weight of the counterweight must be much greater than 10 times. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. The hinge also helped to slow down the system when it reached the bottom. Because we drilled the The easiest counterweight to attach is a small bucket. Since the counterweight weighs in at 1lb, 6oz (on a postal scale), the ideal projectile seems to be a standard glass marble (lighter than I would have guessed, at .2oz). No support or raft needed. So, basically, not. However, as I said earlier, a 1:4 ratio arm isn't going to throw anything very far on its own. recommend you keep the infill high for the pegs, and decently high for the legs, arm, and base. You can vary the weight on the back easily by putting more or fewer rocks inside. 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. $8.95Skeletal Army - Counterweight Trebuchet. To begin, enter the parameters of your trebuchet in the input boxes. Is there anything heavier than a 100 stack of stone (13.00 "weight") that can be used as a counter? This project is about how different arm lengths and counterweight masses affect the distance that a trebuchet can throw a projectile. 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. This cookie is set by GDPR Cookie Consent plugin. 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. Attach the remaining flat part of the paper clip to the other end of the popsicle stick, with the straightened part pointing outward and up (away from the counterweight). Another error How much space do you have to test your trebuchet? Medieval trebuchets were made up of a large triangular base, allowing the large arm to swing a full 360 degrees around, so it could be loaded and fired without the risk of it smashing into its self. Unbend one end of a paper clip so it is almost, but not quite, straight. The animation below shows the motion of the trebuchet as it is fired. This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. (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) If you search online, there are many different plans and designs for building a trebuchet. Figure 3, below, shows a sketch that can help you start thinking about how to set up the problem, and the variables involved. https://www.thingiverse.com/xbxbxb123/designs, For the Trebuchet, I work on the counterweight and the fire arm. 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. 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]. 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. The FAKA is a trebuchet design invented in late 2006 by Craig Macomber. Looking at their advantages and disadvantages, traction trebuchets were probably used for throwing light missiles, whereas the counter-weight trebuchets used for heavy stones. In other words, as long as the release angle is roughly correct, the trebuchet will function as intended. From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). The addition of a fixed counterweight was a major advancement in trebuchet technology. Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. What are various methods available for deploying a Windows application? Model Trebuchet can be made using Stripwood Technology techniques with card and 8mm x 8mm square timber. Artillery has been the centerpiece of many armies over the centuries because of the massive amounts of destruction, fear, and uncertainty it has caused in enemy camps. Press question mark to learn the rest of the keyboard shortcuts. . Trebuchet Mechanics Donald B. Siano dimona@home.com Mar 28, 2001 Abstract 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. Some errors that we might have had in our experiment include, wind, The range of a trebuchet has always been important. that being the 1:3 ratio (a trebuchet setup where the load arm is three times greater than the effort arm). This allows the longer projectile arm to move 4 times as far for each . Thus, sometimes stones were transported a long way: The longer arm length makes the projectile go further because being longer, it multiplies the mechanical force of the counter weight dropping a longer distance, the average was 3.2 meters, then a shorter arm, the average was 2.8 meters. This is exactly as I predicted. The technical storage or access that is used exclusively for anonymous statistical purposes. L1 is the distance between the pivot and the counterweight's attachment point in meters (m). Hence, it really depends how one defines as handling and/or operating. 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. 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. Despite the multitude of builds, very little has been published about. The Hinged Counterweight Trebuchet (HCW) - a standard trebuchet. another potential negative for the trebuchet is its immovability. fit. A trebuchet is a machine where making a change in any one area has an effect on the final result: the fling. How does the mass and height of the counterweight affect the trebuchet system? Most of these items were meant not to destroy walls, but to humiliate the enemy, taint their water supplies, and spread death and disease. As an Amazon Associate I earn from qualifying purchases. For centuries, the trebuchet was the most powerful war machine in the world. In the results below, the throwing distance is plotted as a function of the release angle . What is the best ratio for a trebuchet? too much ballast can result in wasted energy and machine wear. Now, since we covered that part, lets get started. 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. Military History Visualized subscribestar, Military History Visualized Merchandise. (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 website uses cookies to improve your experience while you navigate through the website. The power delivered to a wall from a device like this could be incredibly devastating. because at 5:1, there was not enough power to lift the arm and the projectile between leverage and speed of the arm to achieve the highest velocity. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. What is the best ratio for a trebuchet? 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. Finally, watch your trebuchet go. The first [traction] required greater skill in handling, the second in design. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 279) 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. . Figure 2: Trebuchet near Urquhart Castle on the shores of Loch Ness, Scotland. I designed the basket for 4x1 oz car wheel weights. - Algorithms of a trebuchet, http://www.legionxxiv.org/trebuchetpage/ 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. 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. While this is happening, the wheel is moved backwards by the torque acting on the arm from the counterweight. The traction trebuchet, which was a rather simple design were the force for firing was provided by men pulling down ropes. It was also easier to transport and had a higher rate of fire. holes for our first axle and had to change the axle when the first one that we 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]! with European battles from England to the balkans. The pivoting arm would then stop and the projectile would be flung forward. A 1:1 sling length to throwing arm ratio builds up the best amount of speed for the projectile. 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. Bernhard Kast is a participant in the Amazon EU Associates Programme, an affiliate advertising programme designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.co.uk. The main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. In use for almost 1000 years, the medieval version of the Chinese trebuchet transformed the battlefield thus changing the world forever. What size planking do I need to make a trebuchet? 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. On the other hand, at the 3:1 ratio there was just the right balance By stlfinder.com. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. 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. You also have the option to opt-out of these cookies. measuring, and the axel connection. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet Print instructionsCategory: Mechanical Toys Summary I rebuilt this Trebuchet design in Rhino, made it easier to 3d print. Mold is made of two plywood arcs with holes at the center. Continued As the counterweight trebuchet became more popular, engineers thickened castle walls to withstand heavier bombardment. The lead attached to the NOVA-built, fixed-weight trebuchet weighed a hefty six-and-one-half tons. Trebuchet counterweight? Next, press the "Simulate" button located under the inputs. The counterweight should be 75 to 100 times the weight of the projectile.

He notes: What is in fact surprising, when one comes to consider the dynamics of the counterweight trebuchet, is that it ever became a useful engine of war at all. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 280) 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! 2). Our model uses the following assumptions and physical dimensions: A schematic of the counterweight trebuchet model. Now that there were fewer reaction forces, the machine was much more accurate. (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). Furthermore, Hill assumes that light trebuchets were used to throw missiles into the city, whereas the heavy trebuchets were used for attacking the walls. These improvements helped the trebuchet maintain dominance on the battlefield. The counterweight is cast concrete, 8 inches wide, 15 inch radius from the pivot hole to the curve of the concrete, 108 pounds total. http://imgur.com/CntygEE A nice working trebuchet to throw around small stones, sweets or whatever Use some coins to fill up the counter weight. The Chinese invented the trebuchet in 300BC, the French were . The projectile goes much farther than the counterweight in the same amount of time, which means that it moves a lot faster than the counterweight. Pictures. From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). The From what we know it seems that counter-weight trebuchets were used with heavier missiles. 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. They work great over a huge range of mass ratios. 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. The whipper trebuchet is a modern take on trebuchets, geared toward throwing lighter objects long distance. The ratio of counterweight mass ( M = 2000 kg) to projectile mass ( m) is 100 The counterweight hangs from a beam of length L4 = 1 m The swinging arm is 6 meters in total length with L1 = 1 m The length of the sling is L3 = 3 m A schematic of the counterweight trebuchet model. The main advantages of the counterweight trebuchet were its ability to fire larger stones and require less manpower during operations. https://youtu.be/5RZazivVX7k 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? 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. 24 dimes should be placed in the counterweight. Before the addition of the sling, the crew had to move the entire trebuchet to change the direction of the trajectory. Science Buddies Staff. One of the most famous examples of a trebuchet is that which was used at the siege of Sterling Castle in 1304. weights from Dick's Sports for $6.99 a piece. This cookie is set by GDPR Cookie Consent plugin. it will likely jam, but the counterweight or the arm might also strike the frame. 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. 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. This happens when one end of the sling slips off the tip of the swinging arm. Reproduction of material from this website without written permission is strictly prohibited. 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! A build it yourself trebuchet! While wood is easier to gather, it does consume more wood than reinforcements. A 3D model of Counterweight used in Horizontal Striling Engine, rebuilt this Trebuchet design in Rhino, made it easier to 3d print. The horizontal distance the payload would travel is called the trebuchet's range. How heavy should the counterweight and the payload be? Edward I of England, who had spent months battering the walls of the castle with massive stone and lead projectiles, was becoming sick of the siege going nowhere. Figure 1, below, shows a modern reconstruction of a trebuchet. What tools and safety equipment do you have access to? When the catapult was released, the ropes would twist back into shape and swing the pivoting arm upward until it reached a vertical position and hit a cushioned pad. Repeat steps 4 7 to get two more trials on this arm ratio setting, 9. While the trebuchet is bieng launched, time the throw from when the Ancient Weapon Inspires Student..

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 traction trebuchet was a rather simple construction, the frame was static and connected to the dynamic beam with an axle. Some medieval trebuchets had beams of up to 10 meters and could throw stones of 100 kg as far as 300 meters [1]. 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 Pieces: 166+ pcs Assembly Time: 4h Assembled Size: 14.9x7.8x8.2 in Recommended Age: 14+ Material Description 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. Simple as it seems, the trebuchet is a complicated dynamical system. Whereas the payload was quite varied from 1 kg up to 59 kg (2 lbs to 130 lbs). drill the holes for the smaller axle in the first place. 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. Next, grab the handles and pivot to the angle you want it to fire at, then press the lever to release the brutal weapon. 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. Sling The sling is attached to the long end of the swing arm lever and holds the projectile that is to be thrown. 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). Also, adding wheels could further stabilize the siege machine and enhance the throwing distance of the projectile. How much time do you have to build your trebuchet? Enjoy! 1) and the catapult [1]. Trebuchet Essay. 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. They were created for a terrible purpose, but they're also an amazing example of human ingenuity. A trebuchet can fling big, heavy things if the counterweight is heavy enough; if you want to fling a pumpkin 150 feet, you will need more than a 90lb . Not consenting or withdrawing consent, may adversely affect certain features and functions. Yet, during operations it needed a large amount of manpower. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. Not only coins =) Video https://youtu.be/jpWVBItSfHg And I highly recomend to use this ajustable hook https://www.thingiverse.com/thing:2554790. Due to its low accuracy when targeting units it is ineffective against them. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 277-278) Whereas another scholar notes that modern replicas suggest a range in the order of only 100-120 m, which would be about the same as the traction trebuchet. 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. Some of this energy (not all) will be transformed to kinetic energy of the projectile. Image by Ron L. Toms. 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. the side of the tape the projectile landed, we just looked at the meter tape and 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]. The Floating Everything Trebuchet (FET) - a poor man's FAT, without the vertical guides. Not only does the sling add firing distance to the trebuchet, it gives the crew manning the trebuchet the ability to aim. https://youtu.be/5yMxEXfg85k Credit to Ben Goodwin for helping create this Trebuchet. Enjoy! One nonfictional and historically notable trebuchet is War Wolf (known to the English soldiers at the time as Ludgar). The longer end of the beam would hold the projectile while the shorter end would hold a counter weight [2]. Do you have time to do a fancy design, or do you need to build one quickly? projectile leaves the sling to when it hits the ground, 7. Every city occupied by Mongols in Central . 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. The arm then jerks forward and releases the projectile from the sling. He forced the Scots to remain inside the castle and restarted his siege. und Partner des Werbeprogramms, das zur Bereitstellung eines Mediums fr Websites konzipiert wurde, mittels dessen durch die Platzierung von Werbeanzeigen und Links zu amazon.de Werbekostenerstattung verdient werden knnen. For a sling, I use the handle from a plastic grocery bag. l trebuchet counterweight to projectile weight ratio 3d models . (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. "Effect of Trebuchet Arm Length or Counterweight Mass on Projectile Distance.". Yet, one would assume that proper calculations or laborious trial and errors of various variations could produce an effective counterweight-trebuchet. If you want to do hand calculations to design a trebuchet with the best range, you will need to understand the physics involved. In terms of operating, it depends to a certain degree on the perspective, which one was, Hill notes the following: One of the final improvements to reach the trebuchet was the propped counterweight [3]. 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! Ether way the trebuchet became an essential part of a medieval sieges, and turning up without one was like forgetting to put your trousers on in the morning! . Enjoy! This created an increase in falling distance and centrifugal force, both of which contributed to greater power. 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]. How long should the arm of a trebuchet be? Edwards War Wolf was probably the largest structure most of his men had even seen outside of castles themselves and when the Scottish defenders saw the weapon of mass destruction, they quickly surrendered. Overall, both types of trebuchets were used together during sieges. Necessary cookies are absolutely essential for the website to function properly. When we assembled it with only 120lbs (all the three of us could lift and attach at that height), it threw a Bocce ball roughly 250ft. There are other accounts for other sieges giving a value of about 250 kg (560 lbs). The Chinese needed so much power for the trebuchet that they had up to 250 solders pulling on ropes to operate the machine [6]. CW stands for counterweight, and the release . Please enter a search term in the text box. When the beam is quickly rotated by applying force to the opposite end of . More About scull_mech This is a general description of how to create a floating arm (f2k) trebuchet. The working principle of a trebuchet is simple. 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]. John France notes: For a small trebuchet, you may want to make them 1 foot (30 cm) long; for a larger trebuchet, they can be longer. 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 trebuchet is an ancient siege engine used for throwing large rocks. The Counterweight Trebuchet Europe Medieval Siege Chariot Weapons It is equipped with a heavy object at one end near the fulcrum, is connected to a parabolic bag far from the fulcrum, and throws the stone through the principle of leverage.
