Necessary cookies are absolutely essential for the website to function properly. 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 design originated in medieval times as a siege weapon. 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. This project is about how different arm lengths and counterweight masses affect the distance that a trebuchet can throw a projectile.

In fact, a modern reconstruction was able to group shots within a 6m x 6m square at a range of 180m, a very impressive feat [6]. 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). 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 .

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. This cookie is set by GDPR Cookie Consent plugin. A 1:1 sling length to throwing arm ratio builds up the best amount of speed for the projectile. The hinge also helped to slow down the system when it reached the bottom. The propped counterweight was very similar to the hinged counterweight, except the weight was forced to make an angle with the arm instead of hanging straight down. For an outdoor trebuchet, you can use 2 x 4-inch (5 x 10 cm) planking.

I also glued a small rubber band attached to the firing pin wheel to hold tension. How much time do you have to build your trebuchet? Figure 1, below, shows a modern reconstruction of a trebuchet. Any questions? How much space do you have to test your trebuchet? The poor prospects of surviving an assault from War Wolf prompted the Scottish garrison inside the castle to offer their surrender. General advice is that the optimal ratio is 133:1. 2 stacks of fire arrows are the same. A contemporary image of a trebuchet being loaded SOURCE: medievalists.net. In other words, as long as the release angle is roughly correct, the trebuchet will function as intended. 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. 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. You also have the option to opt-out of these cookies. fit. Next, press the "Simulate" button located under the inputs. In this blog post, we demonstrated that the Multibody Dynamics Module can be used to build a simple model of a counterweight trebuchet. On a trebuchet, it's much closer to the counterweight. The ballista worked well against troops and cavalry, but had no effect upon walls and structures [2]. One is the frame, one is the swing arm, and one is the set of moving parts. This massive weapon was eventually capable of throwing massive boulders over 250 meters, but it did not start that way. 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! (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123-124; Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 275-279). 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. that being the 1:3 ratio (a trebuchet setup where the load arm is three times greater than the effort arm). Some of this energy (not all) will be transformed to kinetic energy of the projectile. See gravitational potential energy. 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. (Weights) - https://www.amazon.com/gp/product/B07XBB4WX6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. Please note: This post contains amazon affiliate links. Simple as it seems, the trebuchet is a complicated dynamical system. listed if standards is not an option). Scrohammer happily hurls these wee glass spheres of doom a surprising distance of 40 feet. 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. How closely do they match? Counterweight is filled with spare change. 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. 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. Less tunable than HCW trebuchets at high ratios. Powered by STLFinder search engine. A build it yourself trebuchet! To begin, enter the parameters of your trebuchet in the input boxes. When assembled it has an internal capacity of 2600ccs. Counterweight powered trebuchet where the counterweight is directly attached to the short arm. Overall, both types of trebuchets were used together during sieges. 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. For a very impressive science project, you could also compare the range of the trebuchet you build to predictions based on hand calculations and/or computer simulations you make (above). The counterweight trebuchet appeared in both Christian and Muslim lands around the Mediterranean in the 12th century. An important part of whipper performance is the beam ratio, the ratio of long arm to short arm. - History and details of the trebuchet, - Plans and directions for building a small trebuchet, http://www.io.com/~beckerdo/other/trebuchet.html. The longer end of the beam would hold the projectile while the shorter end would hold a counter weight [2]. 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) Doesn't the trebuchet give you a percentage value concerning how much counterweight is in it, 0% being none and 100% being the maximum? Below are some examples of different materials used as ballast. 6 What are the advantages of a floating arm trebuchet? The goal of this project is to determine how different physical parameters can affect the range of a trebuchet, using hand calculations, computer simulations, and/or physical experiments. Enjoy! With Just a trebuchet frame and swing arm ready to print. 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. as it ends up shaking around on the A trebuchet built for engineering class. 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. 1. Is there anything heavier than a 100 stack of stone (13.00 "weight") that can be used as a counter? Since the middle ages, however, engineers have developed newer, more efficient styles of the trebuchet. 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.

A small-scale replica of War Wolf, a counterweight trebuchet that uses a boulder-holding sling at the end of a swinging arm. Its role is destroying buildings at long range. For a small trebuchet, you may want to make them 1 foot (30 cm) long; for a larger trebuchet, they can be longer. 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 horizontal distance the payload would travel is called the trebuchet's range. wind could have caused us errors by blowing our projectile off to one side, The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. 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. The word Trebuchet comes from the old French 'Trebucher' meaning 'to throw over', and that is exactly what medieval siege weapons like trebuchets were designed to do. From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. It was also easier to transport and had a higher rate of fire. We launched pumpkins and bowling balls around 10-15 lbs at distances of 300+ feet. 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. Some knowledge of physics will be helpful when doing this project. In use for almost 1000 years, the medieval version of the Chinese trebuchet transformed the battlefield thus changing the world forever. The arm then jerks forward and releases the projectile from the sling. http://www.io.com/~beckerdo/other/trebuchet.html - Plans and directions for building a small trebuchet, http://www.tbullock.com/trebuchet.html They stood as tall as 60 feet (18m) and could fling 80 pound (36kg) objects up to 980 . Where should the pivot point be on the beam? This cookie is set by GDPR Cookie Consent plugin. A trebuchet is a type of catapult that uses a swinging arm to throw a projectile. Licensed under CC BY 3.0, via Wikimedia Commons. 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." These cookies will be stored in your browser only with your consent. 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? Now, at first look, it may be quite surprising why it took so long to develop the counterweight trebuchet, after all, it seems just a simple improvement, but Hill argues that is not the case. Looking at their advantages and disadvantages, traction trebuchets were probably used for throwing light missiles, whereas the counter-weight trebuchets used for heavy stones. The main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. How does the mass and height of the counterweight affect the trebuchet system? Whereas the payload was quite varied from 1 kg up to 59 kg (2 lbs to 130 lbs). One of these more modern designs is the . 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. This cookie is set by GDPR Cookie Consent plugin. Trebuchet (My version) New axes and counterweight, new printable axes, and modified the counterweight. Lets begin with the traction trebuchet, which is an older and simpler design. We tried this, 2 thralls is 100 weight, and is Max for the counterweight. When the counterweight is raised up, it has lots of gravitational potential energy. . 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 traction trebuchet, which was a rather simple design were the force for firing was provided by men pulling down ropes. 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. Despite the multitude of builds, very little has been published about. Actual hand-to-hand combat was quite rare and usually only occurred during midnight counterattacks by the besieged or when the walls of the city were finally breached. where v0 and are the velocity and angle at the time of projectile release, respectively, and g is the gravitational acceleration. From what we know it seems that counter-weight trebuchets were used with heavier missiles. 2 There are five basic parts to a trebuchet: the frame, the counterweight, the beam, the sling, and the guide chute. Edit Rate (0) Tags Discuss History Files . Create an account to follow your favorite communities and start taking part in conversations. Yet, the highest given number in the records was up to 1200 men, which sounds ludicrously high. The floating arm trebuchet uses a counterweight held on top of a tall drop channel to transfer potential energy into kinetic energy. By stlfinder.com. However, as I said earlier, a 1:4 ratio arm isn't going to throw anything very far on its own. Reproduction of material from this website without written permission is strictly prohibited. Do you have specific questions about your science project? They work great over a huge range of mass ratios. 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. Some medieval trebuchets had beams of up to 10 meters and could throw stones of 100 kg as far as 300 meters [1]. Your email address will not be published. I added a cover for the opening to keep kids from adding or removing things. As an Amazon Associate I earn from qualifying purchases. First, tape the AA battery to one end of a popsicle stick. How much counterweight does a trebuchet need? From what we know it seems that counter-weight trebuchets were used with heavier missiles. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123). The counterweight should be 75 to 100 times the weight of the projectile. For any other use, please contact Science Buddies. Figure 2 raises several questions about designing a trebuchet. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet, SummaryI rebuilt this Trebuchet design in Rhino, made it easier to 3d print. 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. Lets see if this holds true for the trebuchet model. 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 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. PLEASE NOTE: Posts and pages contain amazon affiliate links. Continued The optimal trebuchet design is one that launches the payload the farthest horizontal distance. All rights reserved. In movies and computer games Trebuchets are often shown as weapons that can destroy city walls and towers easily. What are the advantages of a floating arm trebuchet? (2006, Oct. 12) Military Technology., [8] R. Meyer, Column One; How Far Can a Piano Fly?, [10] D. Moe. They were created for a terrible purpose, but they're also an amazing example of human ingenuity. The Chinese needed so much power for the trebuchet that they had up to 250 solders pulling on ropes to operate the machine [6]. A 3D model of Counterweight used in Horizontal Striling Engine, rebuilt this Trebuchet design in Rhino, made it easier to 3d print. 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? Its currently set up for a 100:1 counterweight to projectile mass ratio, with 200lbs of counterweight. 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. 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. But John France notes: 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. So, if you are in the business of designing trebuchets for medieval kings, you should pay attention to this design parameter. 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. The main advantages of the counterweight trebuchet were its ability to fire larger stones and require less manpower during operations. An easier way to answer this is 'what didn't they throw'. Image from an illuminated manuscript depicting a Byzantine traction trebuchet at a siege of a citadel, 11th century. Furthermore, Hill assumes that light trebuchets were used to throw missiles into the city, whereas the heavy trebuchets were used for attacking the walls. 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. Now you will build the trebuchet's arm. 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. That's a weight ratio of 1:110. The variables in Figure 3 are as follows: How can you use these variables to calculate the range of a trebuchet? 1) and the catapult [1]. Which brings us to the next point, the overall effectiveness of trebuchets. (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). 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! This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. 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. 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. https://www.thingiverse.com/xbxbxb123/designs, For the Trebuchet, I work on the counterweight and the fire arm. The technical storage or access that is used exclusively for statistical purposes. stones up to 275 meters, obliterating walls in their path[7]. Copyright 2002-2023 Science Buddies. Will allow to have fun in areas such as home and office, for children and adults. The Wikipedia page on trebuchets links to a PDF paper which discusses exactly this question. 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. The Trebuchet works functional but the connection between each parts seems weak and need to be improved. with European battles from England to the balkans. [13] History Forum. This cookie is set by GDPR Cookie Consent plugin. The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1. Press question mark to learn the rest of the keyboard shortcuts. Read the relevant section(s) below for ideas on how to get started on your project. Not only does the sling add firing distance to the trebuchet, it gives the crew manning the trebuchet the ability to aim. 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. If you haven't heard of it, then I will attach . This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. Here is an oversimplified diagram of an armed trebuchet. . Is there anything heavier than a 100 stack of stone (13.00 "weight") that can be used as a counter? 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. (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. Machines Power Source. Whereas the traction trebuchet had the force only applied for a short amount of time. At one end of the beam, a sling is attached to hold the projectile. The long sling, basically provided an almost weightless extension of the beam, thus providing the additional force that compensated for the increased weight of the beam. This website uses cookies to improve your experience while you navigate through the website. Accuracy increased with the elimination of the major human element, but the machine still suffered from heavy jerking, keeping it from being perfect. . The counter-weight is usually much heavier than the projectile, typically by a ratio of 10 to 1 or more. It is assumed that it is a Chinese invention and made its way to Europe via the Arab world around the 9th century. $8.95Skeletal Army - Counterweight Trebuchet. because at 5:1, there was not enough power to lift the arm and the projectile [11] Ripcords Trebuchet Stuff.

Analytical cookies are used to understand how visitors interact with the website. https://youtu.be/5yMxEXfg85k Credit to Ben Goodwin for helping create this Trebuchet. The ballista eventually gave way to the catapult [3]. 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. 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. Unbend one end of a paper clip so it is almost, but not quite, straight. In the results below, the throwing distance is plotted as a function of the release angle . Basic Circuits Kit: Conductors and Insulators. The lead attached to the NOVA-built, fixed-weight trebuchet weighed a hefty six-and-one-half tons. Youll need to cut 8 pieces: Two long base pieces. To fix These super weapons are the result of over two millennia of trial and error that began with the development of the trebuchet. On the other hand, at the 3:1 ratio there was just the right balance 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. Trebuchets were still being used well into the 16 century CE, even though gunpowder weapons had been fairly common on European battle fields for around 100 years. Since they could be mounted on towers they would also outrange the attackers machine. 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. Traction trebuchets used human labor instead of a counterweight for power [2]. . 1 The purpose of this paper is to explain the basic functions of a trebuchet, explain subsystems of the trebuchet, and give examples of a few possible modifications to the subsystems. 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). 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. As an Amazon Associate I earn from qualifying purchases. War Wolf proved its worth, and the rest is, as they say, history. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. The projectile is inside a pouch hanging on a sling attached to the long end of a balancing beam. Yet, one would assume that proper calculations or laborious trial and errors of various variations could produce an effective counterweight-trebuchet. The further between . 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. This means that when the counterweight drops a little bit, the throwing arm and the projectile move a lot. It has many of the advantages of a floating arm trebuchet, but with fewer parts, less friction, and a unique projectile launch path. weights from Dick's Sports for $6.99 a piece. Our team of volunteer scientists can help. 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. However, the king would not have it, as he was eager to try out his new trebuchet. With this power, a trebuchet could destroy even fortified walls quite easily and quickly replaced catapults as the weapon of choice on the medieval battlefield. I needed about 5 lbs so I used 2 plates and adapters and cable-tied them together. Gravity.
