The trebuchet was preferred over a catapult due to its greater range capability and greater accuracy. The Chinese needed so much power for the trebuchet that they had up to 250 solders pulling on ropes to operate the machine [6]. The counterweight is raised and the trebuchet is cocked. Consenting to these technologies will allow us to process data such as browsing behavior or unique IDs on this site. How heavy should the counterweight and the payload be? Simplest of all trebuchet designs mechanically. General advice is that the optimal ratio is 133:1. The force that the catapult needed to launch the projectile came from the manipulation of twisted ropes [3]. 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. This is exactly as I predicted. The pivoting arm would then stop and the projectile would be flung forward. The ratio of the mass of the counterweight to the mass of the payload, expressed as CW:P. A typical MR is 100:1. 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 hinge also helped to slow down the system when it reached the bottom. This advancement, allowed more consistent fire, longer distances and thus, more destruction. (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. [7] Encyclopedia Britannica. Adult supervision is required when building and operating a trebuchet. The main beam, counterweight box, sling, projectile, trough, windlass, and framework are all clearly visible with dimensions given for some of the component parts. The Art of the Catapult: Build Greek Ballistae, Roman Onagers, English Trebuchets, and More Ancient Artillery, If you have knowledge of basic physics concepts like, Can you derive equations that describe the position of the payload as a function of time, before. these errors, we could test it on a less windy day, be more careful timing, and in measurements that we had was in the timing. This massive weapon was eventually capable of throwing massive boulders over 250 meters, but it did not start that way. 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. Once the arm was in place, the projectile would be loaded into a cup at the end of the arm. Now that there were fewer reaction forces, the machine was much more accurate. How much counterweight does a trebuchet need? The longer end of the beam would hold the projectile while the shorter end would hold a counter weight [2]. 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. One of these more modern designs is the . 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. One of the most advanced siege engines used in the Middle Ages was the trebuchet, which used a large counterweight to store energy to launch a payload, or projectile. Internet: http://www.trebuchet.com, [Oct. 11, 2006]. 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. From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). All rights reserved. Yet, this depictions seems to be a big over exaggerated. Thus, although it was a rather simple machine, the handling required quite some training and coordination. Do you have a large outdoor area to test a big one? Trebuchet counterweight? The FAKA is a trebuchet design invented in late 2006 by Craig Macomber. The projectile undergoes a swinging motion and is released at some suitable position along its trajectory. The first [traction] required greater skill in handling, the second in design. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 279) A trebuchet is a type of catapult that uses a swinging arm to throw a projectile. 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. These cookies track visitors across websites and collect information to provide customized ads. The person who was timing started the watch when the projectile was 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. The trebuchet is the hallmark of medieval siege warfare and is synonymous. Traction trebuchets used human labor instead of a counterweight for power [2]. 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. Some medieval trebuchets had beams of up to 10 meters and could throw stones of 100 kg as far as 300 meters [1]. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet, SummaryI rebuilt this Trebuchet design in Rhino, made it easier to 3d print. [12] J. Vaughan. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Figure 2, below, shows a diagram of a trebuchet with the main parts labeled. Do you have time to do a fancy design, or do you need to build one quickly? Whatever you decide you want to launch with your trebuchet, your counterweight should be from 100 to 133 times the weight of your projectile. The counter-weight is usually much heavier than the projectile, typically by a ratio of 10 to 1 or more. No support or raft needed. 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. If you haven't heard of it, then I will attach . When the counterweight is raised up, it has lots of gravitational potential energy. Drill a small hole into the back end of the swing arm about 1 inch (2.5 cm) from the end. [Weapons 101] Trebuchet - How they work - Traction & Counterweight Trebuchets Medieval Equipment Military History Visualized 190K views 6 years ago How to Operate a Mini Trebuchet Joe Staggs. Model Trebuchet can be made using Stripwood Technology techniques with card and 8mm x 8mm square timber. of your trebuchet be? Machines Power Source. Anyone who has played Age of Empires (this includes me, yes), will know exactly what a trebuchet is, and what it does. h is the initial height of the counterweight off the ground. 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]! The Chinese needed so much power for the trebuchet that they had up to 250 solders pulling on ropes to operate the machine [6]. 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. 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. 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. Powered by STLFinder search engine. Hence, it really depends how one defines as handling and/or operating. 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). Trebuchet with variable arm ratios, 2. 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. Ancient and Medieval Siege Weapons: A Fully Illustrated Guide to Siege Weapons and Tactics. 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. They stood as tall as 60 feet (18m) and could fling 80 pound (36kg) objects up to 980 . The maximum throwing distance is obtained if the projectile is released at 38. Copyright 2002-2023 Science Buddies. Basic Circuits Kit: Conductors and Insulators. This created an increase in falling distance and centrifugal force, both of which contributed to greater power. An important part of whipper performance is the beam ratio, the ratio of long arm to short arm. 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 The construction and operation of the counterweight-trebuchet was the province of specialist engineers, who were not always available, and it was ponderous to transport. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123) stones up to 275 meters, obliterating walls in their path[7]. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. In the Middle Ages, soldiers had to make sure their trebuchets had a long enough range to stay outside the range of defending archers on castle walls. The Wikipedia page on trebuchets links to a PDF paper which discusses exactly this question. The trebuchet had a problem of sagging to one side, so I made some guy wires to hold everything relatively straight. The counterweight is usually very heavy and provides the mechanical force to fire. I needed about 5 lbs so I used 2 plates and adapters and cable-tied them together. The easiest counterweight to attach is a small bucket. 6 What are the advantages of a floating arm trebuchet? To begin, enter the parameters of your trebuchet in the input boxes. Will you need help from an adult to use tools like a power drill or saw? The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1. I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. Can you pick these parameters based on hand calculations or computer simulations (above), or based on design information you found through your own research? page revision: 7, last edited: 29 Jan 2011 23:58. Not only coins =) Video https://youtu.be/jpWVBItSfHg And I highly recomend to use this ajustable hook https://www.thingiverse.com/thing:2554790. We tried 100x Ironstone ore (10.00 "weight") and Heavy Armor, but none of it seemed to work better. 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. 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). On the other hand, at the 3:1 ratio there was just the right balance The first of these, a "black box" model in which the mechanism for the Whereas the traction trebuchet had the force only applied for a short amount of time. What size planking do I need to make 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. (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: We do this to improve browsing experience and to show personalized ads. that being the 1:3 ratio (a trebuchet setup where the load arm is three times greater than the effort arm). . 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. 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. In this blog post, we demonstrated that the Multibody Dynamics Module can be used to build a simple model of a counterweight trebuchet. 1) and the catapult [1]. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. Not only does the sling add firing distance to the trebuchet, it gives the crew manning the trebuchet the ability to aim. 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. Military History Visualized subscribestar, Military History Visualized Merchandise. Overall, both types of trebuchets were used together during sieges. Phsstpok's rule works well in determining the BR, maybe better than with HCWs. Try for yourself by downloading the model file from our Application Gallery. Based on historical designs, it stands 18 metres (59 ft) tall and throws missiles typically 36 kg (80 lbs) up to 300 metres (980 ft). 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). A trebuchet (French trbuchet) is a siege engine used in the Middle Ages. The longer the ratio, the greater the speed that tip of the throwing arm will reach but also increasing the force required to move it quickly. However, the king would not have it, as he was eager to try out his new trebuchet. 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? 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. The floating arm trebuchet uses a counterweight held on top of a tall drop channel to transfer potential energy into kinetic energy. If you search online, there are many different plans and designs for building a trebuchet. 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. between leverage and speed of the arm to achieve the highest velocity. Is there anything heavier than a 100 stack of stone (13.00 "weight") that can be used as a counter? If you are trebbing and run out of wood or iron, you can keep repairing the trebuchet up to 2500/5000 health with only one of the mats! The counterweight trebuchet appeared in both Christian and Muslim lands around the Mediterranean in the 12th century. How much space do you have to test your 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. 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. Note: A trebuchet utilizes specific measurements to throw a projectile using the power of a falling weight. Enjoy! PLEASE NOTE: Posts and pages contain amazon affiliate links. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 124), Note that trebuchets were not only used in the offense, quite on the contrary, there were also used effectively by defenders. Mold is made of two plywood arcs with holes at the center. [Siege of Acre (1189-1191)]. Since they could be mounted on towers they would also outrange the attackers machine. The projectile is inside a pouch hanging on a sling attached to the long end of a balancing beam. trebuchet. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 274 & 280). [5] Wikipedia. There is more than one way to tackle the problem. There is a small trebuchet competition, You are allowed a maximum height of 1 meter, when it's in the cocked position, and the supplied ammo will be tennis balls. Yet, during operations it needed a large amount of manpower. 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. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Catapulting Science Into Fun.. Never "dry fire" the trebuchet - always load a projectile to balance the firing mechanism. Military History Visualized Offical Homepage for the YouTube Channel. As an Amazon Associate I earn from qualifying purchases. CW stands for counterweight, and the release . Gurstelle once made a large trebuchet with a 500-pound (226-kilogram) counterweight that was still only powerful enough to launch a small cantaloupe. However, there have been occasions where trebuchets could reduce the wall to rubble in a few shots. 1. Chinese Siege Warfare: Mechanical Artillery & Siege Weapons of Antiquity An Illustrated History Internet: http://authors.historyforum.com/liang_jieming/chinesesiegewarfare>. 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 trebuchet consists of a long beam placed off center on a pivot on a large base that would support the entire apparatus (Fig. An easier way to do it might be to find the Lagrangian of the system, KE-U, and find the equations of motion from that. 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. Its currently set up for a 100:1 counterweight to projectile mass ratio, with 200lbs of counterweight. A trebuchet is a machine where making a change in any one area has an effect on the final result: the fling. 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? Medieval battlefields consisted mainly of sieges to fortified cities by some hostile force. What is the best ratio for a trebuchet? Levers provide a fixed movement ratio between the projectile end of the arm and the CW end of the arm. Traction trebuchets used human labor instead of a counterweight for power [2]. 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. Image from an illuminated manuscript depicting a Byzantine traction trebuchet at a siege of a citadel, 11th century. The Hinged Counterweight Trebuchet (HCW) - a standard trebuchet. Ancient Weapon Inspires Student.. 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. 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. Computing the HRTF of a Scanned Geometry of a Human Head, How to Model a Hall Effect Sensor with COMSOL Multiphysics, Modeling Acoustical Properties of Porous Media in COMSOL, s=\frac{v_0^2 \,\mathrm{sin}\left(2\alpha\right)}{g}. How high off the ground should the pivot be? weights from Dick's Sports for $6.99 a piece. 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. Next, press the "Simulate" button located under the inputs. Lets see if this holds true for the trebuchet model. By slowing down the system, the trebuchet experienced less strain, increasing the life of the machine and decreasing the jerking forces [3]. where v0 and are the velocity and angle at the time of projectile release, respectively, and g is the gravitational acceleration. 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]. It does not store any personal data. When assembled it has an internal capacity of 2600ccs. Although, the counterweight-trebuchet was quite a feat in engineering, its influence on warfare was limited and the balance between offense and defense was not altered significantly. 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! Counterweight powered trebuchet where the counterweight is directly attached to the short arm. While designers of the Middle Ages had to rely largely on intuition or trial and error to build their trebuchets, modern builders have many helpful tools available. These improvements helped the trebuchet maintain dominance on the battlefield. connection. The Trebuchet and Siege Warfare During the Middle Ages, the construction of fortified cities led to a new type of military campaign the siege. For a small trebuchet, you may want to make them 1 foot (30 cm) long; for a larger trebuchet, they can be longer. If you want to do hand calculations to design a trebuchet with the best range, you will need to understand the physics involved. Before the addition of the sling, the crew had to move the entire trebuchet to change the direction of the trajectory. forcing the projectile out of the leather bag and onto the target. From what we know it seems that counter-weight trebuchets were used with heavier missiles. Furthermore, Hill assumes that light trebuchets were used to throw missiles into the city, whereas the heavy trebuchets were used for attacking the walls. I added a cover for the opening to keep kids from adding or removing things. 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) 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. To fix The trebuchet is a large siege weapon that you might recognize from movies set in the Middle Ages or fantasy worlds. It is assumed that it is a Chinese invention and made its way to Europe via the Arab world around the 9th century. 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. 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). holes for our first axle and had to change the axle when the first one that we Physics involved came from the manipulation of twisted ropes [ 3 ] the hallmark of siege...
