(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) 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. When the beam is quickly rotated by applying force to the opposite end of . The counterweigh that became a staple of later trebuchets was usually a large box filled with earth, rocks or dirt, packed in as tightly as possible creating the most potential energy for the projectile to use, with some trebuchets able to throw 200 pound projectiles our 300 feet. Two of the major predecessors of the trebuchet were the ballista (Fig. Trebuchet with variable arm ratios, 2. It . I assume if one includes maintenance into handling that the counterweight trebuchet was harder to handle. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 280-282) The pivoting arm would then stop and the projectile would be flung forward. Any questions? The Image by Ron L. Toms.

With starting and stopping points this uncertain, there could have been Trebuchet. http://www.io.com/~beckerdo/other/trebuchet.html - Plans and directions for building a small trebuchet, http://www.tbullock.com/trebuchet.html 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 . Try for yourself by downloading the model file from our Application Gallery. The simplest trebuchet is basically a throwing arm pivoted on a fulcrum. When assembled it has an internal capacity of 2600ccs. This is why more than one wheel is used. Counterweight powered trebuchet where the counterweight is directly attached to the short arm. Military History Visualized Offical Homepage for the YouTube Channel. (2006, Oct. 12) Military Technology., [8] R. Meyer, Column One; How Far Can a Piano Fly?, [10] D. Moe. https://youtu.be/5yMxEXfg85k Credit to Ben Goodwin for helping create this Trebuchet. Is there anything heavier than a 100 stack of stone (13.00 "weight") that can be used as a counter? Do you have time to do a fancy design, or do you need to build one quickly? The trebuchet had a problem of sagging to one side, so I made some guy wires to hold everything relatively straight. On the other hand, at the 3:1 ratio there was just the right balance Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. Gurstelle once made a large trebuchet with a 500-pound (226-kilogram) counterweight that was still only powerful enough to launch a small cantaloupe. pushing it forward, or pushing it backwards. Thus, sometimes stones were transported a long way: Your email address will not be published. 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. 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. What about moments of inertia, which are not labeled in Figure 3? http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet, SummaryI rebuilt this Trebuchet design in Rhino, made it easier to 3d print. For example, when I first shot my trebuchet I was using a 2.26kg payload and a 22.6kg counterweight. These improvements helped the trebuchet maintain dominance on the battlefield. Defenders used trebuchets against siege towers and the enemy artillery, thus providing what we would call counter-battery fire nowadays. For a sling, I use the handle from a plastic grocery bag. [13] History Forum. We launched pumpkins and bowling balls around 10-15 lbs at distances of 300+ feet. So, basically, not. 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. The hinge greatly increased the efficiency of the motion involving the counterweight, causing more power to be delivered to the 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. 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. The major drawbacks were it a complex machine and required specialists that were rare and few. First, tape the AA battery to one end of a popsicle stick. However, as I said earlier, a 1:4 ratio arm isn't going to throw anything very far on its own. Powered by STLFinder search engine. too much ballast can result in wasted energy and machine wear. 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. https://youtu.be/Hb05YVnp0Tw. Cocking . Enjoy! The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1. 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 range of a trebuchet has always been important. The design originated in medieval times as a siege weapon. 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. Medieval battlefields consisted mainly of sieges to fortified cities by some hostile force. It has many of the advantages of a floating arm trebuchet, but with fewer parts, less friction, and a unique projectile launch path. 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. Will you need help from an adult to use tools like a power drill or saw? When the counterweight is raised up, it has lots of gravitational potential energy. Adult supervision is required when building and operating a trebuchet. On one end of the beam was a nest, sling or other element for holding the payload attached and on the other end several ropes for men pulling down the beam in order to provide enough force to propel the payload. 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) 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. 2 stacks of fire arrows are the same. these errors, we could test it on a less windy day, be more careful timing, and 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. many timing errors. One of the final improvements to reach the trebuchet was the propped counterweight [3]. While this is happening, the wheel is moved backwards by the torque acting on the arm from the counterweight. listed if standards is not an option). 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. of your trebuchet be? How high off the ground should the pivot be? 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. General wisdom has a 5:1 ratio being the norm for a standard trebuchet, although 4:1 is sometimes used. In the fall of 2005, he was pursuing a B.S. The further between . The whipper trebuchet is a modern take on trebuchets, geared toward throwing lighter objects long distance. For a small trebuchet, you may want to make them 1 foot (30 cm) long; for a larger trebuchet, they can be longer. Record the distance and time on a piece of paper, 8.

Here is an oversimplified diagram of an armed trebuchet. Copyright 2002-2023 Science Buddies. Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare 1000-1300. A contemporary image of a trebuchet being loaded SOURCE: medievalists.net. But John France notes: The actual size of War Wolf is unknown but, we do know that once dissembled, the parts fit into over 30 wagons and modern estimates have the massive structure at over 300 feet tall. PLEASE NOTE: Posts and pages contain amazon affiliate links. In movies and computer games Trebuchets are often shown as weapons that can destroy city walls and towers easily. A trebuchet is a type of catapult that uses a swinging arm to throw a projectile. Scrohammer happily hurls these wee glass spheres of doom a surprising distance of 40 feet. Youll need to cut 8 pieces: Two long base pieces. 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. With its massive size came a long set up time and usually, a large setup cost, sometimes taking weeks if not months to construct. The horizontal distance the payload would travel is called the trebuchet's range. Is a full counter weight of 100 stone stacks the max power/range of the Treb? We tried 100x Ironstone ore (10.00 "weight") and Heavy Armor, but none of it seemed to work better. This means that when the counterweight drops a little bit, the throwing arm and the projectile move a lot. . However, since the trebuchet is much easier to aim at a large stationary target than small mobile targets, it was usually much more effective for the side laying siege[1]. Do you have specific questions about your science project? The Hinged Counterweight Trebuchet (HCW) - a standard trebuchet. For an outdoor trebuchet, you can use 2 x 4-inch (5 x 10 cm) planking. How does the mass and height of the counterweight affect the trebuchet system? Assembly video: Below are some examples of different materials used as ballast. We use technologies like cookies to store and/or access device information. These cookies track visitors across websites and collect information to provide customized ads. 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 work great over a huge range of mass ratios. [12] J. Vaughan. Gravity. Create an account to follow your favorite communities and start taking part in conversations. 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. 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. Enjoy! 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! made broke, the connection between the new axle and the arm was loose and Ancient Weapon Inspires Student.. See gravitational potential energy. 3). be 3:1 and not 5:1. 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. How long should the arm of a trebuchet be? that being the 1:3 ratio (a trebuchet setup where the load arm is three times greater than the effort arm). Our model uses the following assumptions and physical dimensions: A schematic of the counterweight trebuchet model. 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. It is rumoured that Edward was so keen on trying out his new toy that he ordered the recently surrendered Scots back into the castle, quoted to have said "You do not deserve any grace, but must surrender to my will" and to prepare to feel the full might of the English crown, in the form of a bombardment from War Wolf. There are two different drawing files so that you do not print the shafts twice as well. Thanks. At one end of the beam, a sling is attached to hold the projectile. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". 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. As the counterweight trebuchet became more popular, engineers thickened castle walls to withstand heavier bombardment. 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). Once the arm was in place, the projectile would be loaded into a cup at the end of the arm. 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. 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. 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. These super weapons are the result of over two millennia of trial and error that began with the development of the 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. A trebuchet is a type of catapult that uses a counterweight to engage the armwhich is attached to a slingand launch projectiles. From what we know it seems that counter-weight trebuchets were used with heavier missiles. Now, lets examine what happens if we modify the length of the sling by 10% using a parametric sweep. However, the king would not have it, as he was eager to try out his new trebuchet. The counter-weight arm of the seesaw is usually shorter than the projectile arm by a ratio of 4 to 1 or more. We also use third-party cookies that help us analyze and understand how you use this website. 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. When the trebuchet is fired, the counterweight drops, and the potential energy of the system is converted into a combination of kinetic and potential energy. These references will be useful for learning about the physics of trebuchets. Since they could be mounted on towers they would also outrange the attackers machine. This weapon is built on the idea of converting potential energy into kinetic energy to hurl a projectile over a large distance. One of these more modern designs is the . I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. Why is it a complicated design? 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. Read the documentation or contact us. In order to maximize the distance the projectile flies, the trebuchet needs to have a relatively long throwing arm compared to the counterweights arm, and a relatively large weight relative to the object being thrown. weights from Dick's Sports for $6.99 a piece. 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. The sling is attached to the end of the long arm of the lever. This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. it will likely jam, but the counterweight or the arm might also strike the frame. Not only coins =) Video https://youtu.be/jpWVBItSfHg And I highly recomend to use this ajustable hook https://www.thingiverse.com/thing:2554790. Internet: http://www.ripcord.ws, [Oct. 11, 2006]. A trebuchet is a medieval stone-throwing war engine. We tried 100x Ironstone ore (10.00 "weight") and Heavy Armor, but none of it seemed to work better. Mc=30, Mp=0.5, Sa= -46, and Lc=0.321 or 0.5. The cookies is used to store the user consent for the cookies in the category "Necessary". (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). . There are many different approaches to building a trebuchet, and you can find many different guides and designs online and in books (see the Bibliography for one example). released and stopped it when it landed, which could have been 60 M away. Necessary cookies are absolutely essential for the website to function properly. Not only does the sling add firing distance to the trebuchet, it gives the crew manning the trebuchet the ability to aim. The catapult consisted of a solid base with a pivoting arm that would be pulled down and locked into place [1]. Uninterrupted action by massed forces of large machines would surely have smashed masonry in time, but the conditions in which large numbers of such machines could be gathered and operated were relatively rare, and before the end of the twelfth century there is little evidence of artillery smashing the main masses of castles and walled cities. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 120), Another aspect in attacking walls was, that the quality of the stones was very important, because if the stone shatters on the wall, the damage is quite limited. The catapult operator would twist ropes that surrounded the pivoting arm, causing immense tension. Image from an illuminated manuscript depicting a Byzantine traction trebuchet at a siege of a citadel, 11th century. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 119) 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! [5] Wikipedia. John France notes: 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 . 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).
