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! I designed the basket for 4x1 oz car wheel weights. The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1. Anyone who has played Age of Empires (this includes me, yes), will know exactly what a trebuchet is, and what it does. A trebuchet (French trbuchet) is a siege engine used in the Middle Ages. 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. One can expect that only a limited number of these special stones were available and used. 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. Repeat steps 4 8 for all ten settings. h is the initial height of the counterweight off the ground. [13] History Forum. Try for yourself by downloading the model file from our Application Gallery. This allows for the beam to rotate vertically through a wide arc (typically over 180). https://youtu.be/5yMxEXfg85k Credit to Ben Goodwin for helping create this Trebuchet. Our model uses the following assumptions and physical dimensions: A schematic of the counterweight trebuchet model. Rolling wheels prevent the crushing lurch. Now, lets examine what happens if we modify the length of the sling by 10% using a parametric sweep. 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 first of these, a "black box" model in which the mechanism for the How closely do they match?

To begin, enter the parameters of your trebuchet in the input boxes. 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. For any other use, please contact Science Buddies. Of course, the hanging CW trebuchet sacrifices counterweight fall distance for this efficiency. and a hose clamp to hold the counterweight on. The catapult consisted of a solid base with a pivoting arm that would be pulled down and locked into place [1]. When the counterweight is raised up, it has lots of gravitational potential energy. Toystub Trebuchet Kit Puzzle 3D Wood Puzzle Wooden Models for Teen. The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1. Copyright 2002-2023 Science Buddies. 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. 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. Enjoy! Can you pick these parameters based on hand calculations or computer simulations (above), or based on design information you found through your own research? This consent may be withdrawn. He forced the Scots to remain inside the castle and restarted his siege. This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. VirtualTrebuchet is a web based trebuchet simulator that will allow you to quickly evaluate different trebuchet configurations. Lets see if this holds true for the trebuchet model. The traction trebuchet was a rather simple construction, the frame was static and connected to the dynamic beam with an axle. I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. The weight of the counterweight must be much greater than 10 times. While the trebuchet is bieng launched, time the throw from when the It . The poor prospects of surviving an assault from War Wolf prompted the Scottish garrison inside the castle to offer their surrender. it will likely jam, but the counterweight or the arm might also strike the frame. https://youtu.be/5RZazivVX7k 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. Summary: The trebuchet, in all its forms, was very much in vogue in the reenactment and research community in the 1980s and 1990s. Trebuchets have appeared in several films and TV shows, such as The Return of the King (2003); Marco Polo (20142016); and even in Monty Python and the Holy Grail (1975), where a cow was catapulted from inside the castle walls toward an unsuspecting King Arthur! The trebuchet consists of a long beam placed off center on a pivot on a large base that would support the entire apparatus (Fig. Can you make a trip to the hardware store and build your trebuchet with wood, nuts, and bolts? Whereas the payload was quite varied from 1 kg up to 59 kg (2 lbs to 130 lbs). 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 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. The main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. Related. This cookie is set by GDPR Cookie Consent plugin. It considers several models of varying complexity and finds a maximum range efficiency of 83% for a 100 pound counterweight, 1 pound projectile, a 5 foot long beam pivoted 1 foot from the point of attachment of the counterweight, and a 3.25 foot long . The cookie is used to store the user consent for the cookies in the category "Analytics". All weapons have their pros and cons with the trebuchet having its fair share of both. trebuchet. Press the backs of your hands against the inside of a door frame for 30 secondsas if youre trying to widen the frameand then let your arms down; youll feel something odd. I assume if one includes maintenance into handling that the counterweight trebuchet was harder to handle. At one end of the beam, a sling is attached to hold the projectile. Image from an illuminated manuscript depicting a Byzantine traction trebuchet at a siege of a citadel, 11th century. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. 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. Internet: http://www.ripcord.ws, [Oct. 11, 2006]. The longer end of the beam would hold the projectile while the shorter end would hold a counter weight [2]. 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. General advice is that the optimal ratio is 133:1. The projectile is inside a pouch hanging on a sling attached to the long end of a balancing beam. Conan Exiles How To Make Trebuchet, Ammo, and Damage Test!https://www.twitch.tv/cainebourneCheck out our server and play with us!YogsPlayground IP 162.251.1. A trebuchet has a lever arm with a large, heavy counterweight on one end and a smaller projectile on the other end. That's a weight ratio of 1:110. What tools and safety equipment do you have access to? 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 range of a trebuchet has always been important. L3 is the length of the sling (m). If this is the case (although it might be I'm just remembering wrong) then it really shouldn't matter what you throw in it as long as you get the percentage you want. 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. Thus, sometimes stones were transported a long way: This created an increase in falling distance and centrifugal force, both of which contributed to greater power. Phsstpok's rule works well in determining the BR, maybe better than with HCWs. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". Furthermore, Hill assumes that light trebuchets were used to throw missiles into the city, whereas the heavy trebuchets were used for attacking the walls. We tried 100x Ironstone ore (10.00 "weight") and Heavy Armor, but none of it seemed to work better. By stlfinder.com. 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. Figure 2 raises several questions about designing a trebuchet. The main advantages of the traction trebuchet were that it was faster and cheaper to build and needed no specialists, unlike the counterweight trebuchet. It will take 1-2 iron reinforcements to repair it back up to 2500 health after each boulder. Christopher Carrillo was born in Monterey Park, CA. One is the frame, one is the swing arm, and one is the set of moving parts. 2 How long should the arm of a trebuchet be? Our team of volunteer scientists can help. 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. However, there have been occasions where trebuchets could reduce the wall to rubble in a few shots. You also have the option to opt-out of these cookies. In use for almost 1000 years, the medieval version of the Chinese trebuchet transformed the battlefield thus changing the world forever. This aspect of warfare has made tremendous advancements throughout history, with current artillery weapons having the capability of sending projectiles past the horizon and landing within a few feet of their intended targets. One of the final improvements to reach the trebuchet was the propped counterweight [3]. An easier way to answer this is 'what didn't they throw'. of your trebuchet be? The ballista was a type of large crossbow that worked very much like a bow, using the tension created by pulling back a string or rope along with a trigger mechanism to fire spear-like ammunition [2]. No support or raft needed. Now you will build the trebuchet's arm. 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. Your email address will not be published. These cookies track visitors across websites and collect information to provide customized ads. 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]. Record the distance and time on a piece of paper, 8. The working principle of a trebuchet is simple. The optimal trebuchet design is one that launches the payload the farthest horizontal distance. Hurl those stones. The trebuchet is a large siege weapon that you might recognize from movies set in the Middle Ages or fantasy worlds. 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. Figure 3: Trebuchet on the grounds of Caerlaverock Castle, Scotland. 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. Figure 2, below, shows a diagram of a trebuchet with the main parts labeled. The hinge also helped to slow down the system when it reached the bottom. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet, I rebuilt this Trebuchet design in Rhino, made it easier to 3d print.

Another error While wood is easier to gather, it does consume more wood than reinforcements. Gurstelle once made a large trebuchet with a 500-pound (226-kilogram) counterweight that was still only powerful enough to launch a small cantaloupe. 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. Licensed under CC BY 3.0, via Wikimedia Commons. 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 arm then jerks forward and releases the projectile from the sling. I needed about 5 lbs so I used 2 plates and adapters and cable-tied them together. 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. 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. 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. A large counterweight trebuchet. (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) They stood as tall as 60 feet (18m) and could fling 80 pound (36kg) objects up to 980 . Some errors that we might have had in our experiment include, wind, By slowing down the system, the trebuchet experienced less strain, increasing the life of the machine and decreasing the jerking forces [3]. In either case, can you make your analysis more realistic by accounting for things like friction and air resistance? The projectile undergoes a swinging motion and is released at some suitable position along its trajectory. Using a parametric sweep, you could easily examine the effect of changing other physical lengths in the model (while keeping the counterweight at fixed height for consistency). These improvements helped the trebuchet maintain dominance on the battlefield. 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]. From what we know it seems that counter-weight trebuchets were used with heavier missiles. 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. The main beam, counterweight box, sling, projectile, trough, windlass, and framework are all clearly visible with dimensions given for some of the component parts. 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 added a cover for the opening to keep kids from adding or removing things. The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. The fulcrum of the lever (usually an axle) is supported by a high frame, and the counterweight is suspended from the short arm of the lever. The simplest trebuchet is basically a throwing arm pivoted on a fulcrum. This cookie is set by GDPR Cookie Consent plugin. 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. $8.95Skeletal Army - Counterweight Trebuchet. Please enter a search term in the text box. weights from Dick's Sports for $6.99 a piece. This is exactly as I predicted. 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). 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. 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. 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. Less tunable than HCW trebuchets at high ratios. 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]. This abbreviated engineering project idea will help you get started with three different ways to investigate what factors can increase the range of a trebuchet: You can decide whether you want to try just one, two, or all three of these approaches. To do better, you'll want a sling. Reproduction of material from this website without written permission is strictly prohibited. Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare 1000-1300. 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? Yet, the highest given number in the records was up to 1200 men, which sounds ludicrously high. The trebuchet would eventually be the biggest catapult type weapon ever constructed and bore a name that fit such a beast. Unbend one end of a paper clip so it is almost, but not quite, straight. 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. Science Buddies Staff. Trebuchet Essay. I would recommend bring at least 2-300 . I was able to use the collars from my weight set to hold the weights as they were slightly bigger than 1". What size planking do I need to make a trebuchet? Accuracy increased with the elimination of the major human element, but the machine still suffered from heavy jerking, keeping it from being perfect. Below are some examples of different materials used as ballast. wind could have caused us errors by blowing our projectile off to one side, Next, grab the handles and pivot to the angle you want it to fire at, then press the lever to release the brutal weapon. stones up to 275 meters, obliterating walls in their path[7]. Since the middle ages, however, engineers have developed newer, more efficient styles of the trebuchet. A trebuchet is a medieval stone-throwing war engine. 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 . Adult supervision is required when building and operating a trebuchet. 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! We use technologies like cookies to store and/or access device information. The traction trebuchet, which was a rather simple design were the force for firing was provided by men pulling down ropes. (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). 2020 by History University. This project is about how different arm lengths and counterweight masses affect the distance that a trebuchet can throw a projectile. 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. The person who was timing started the watch when the projectile was Answer (1 of 5): I would guess you would do exponentially better to launch small arrows with a high rate of fire, except that arrows could potentially be cast aside by wind over medium or long distances, hence the need for propellant and guidance and modern warfare techniques. 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) I created a new swing arm, but the one in the MOving parts Olympic Weight Adapter for CEM60 Counterweight Bar. [5] Wikipedia. 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. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Edit Rate (0) Tags Discuss History Files . another potential negative for the trebuchet is its immovability. War Wolf was the largest trebuchet ever made and was rumored to send boulders of about 150 kilograms across a distance of over 200 meters. The 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! Pieces: 166+ pcs Assembly Time: 4h Assembled Size: 14.9x7.8x8.2 in Recommended Age: 14+ Material Description 4.4 4.4 out of 5 stars (13) $32.99 $ 32. 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. Thus, the counter-weight trebuchet had to be constructed with a stronger beam, which reduces its effectiveness quite considerably.

[Check out this Video of a small modern rebuild of a real life traction trebuchet], [Check out this video of a rebuild of traction trebuchet in the game Besiege]. The trebuchet is the hallmark of medieval siege warfare and is synonymous. What is your budget, and what materials do you have access to? Despite the multitude of builds, very little has been published about. Pick something with a high ratio of strength to weight. Every city occupied by Mongols in Central . I made a "trigger" for the catapult out of two big shackles and a rod . Your internet explorer is in compatibility mode and may not be displaying the website correctly.

Might want to attach something heavier to act as a counter weight. Whatever you decide you want to launch with your trebuchet, your counterweight should be from 100 to 133 times the weight of your projectile. A small-scale replica of War Wolf, a counterweight trebuchet that uses a boulder-holding sling at the end of a swinging arm. When the beam is quickly rotated by applying force to the opposite end of . The hinge greatly increased the efficiency of the motion involving the counterweight, causing more power to be delivered to the projectile. Consenting to these technologies will allow us to process data such as browsing behavior or unique IDs on this site. I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. It is assumed that it is a Chinese invention and made its way to Europe via the Arab world around the 9th century. 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]. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123), Lets take a short look at the main differences of the Traction and Counterweight Trebuchets: Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. in measurements that we had was in the timing. - History behind the trebuchet, http://www.ripcord.ws/theory.html The easiest counterweight to attach is a small bucket. 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. They work great over a huge range of mass ratios. The ratio of the mass of the counterweight to the mass of the payload, expressed as CW:P. A typical MR is 100:1. 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. Simplest of all trebuchet designs mechanically. (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) drill the holes for the smaller axle in the first place.
