trebuchet counterweight ratio

(France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 120). 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). m2 is the mass of the payload (kg). 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 . Please note: This post contains amazon affiliate links. A counterweight trebuchet is powered by a very heavy counterweight, acting on a lever arm. We tried 100x Ironstone ore (10.00 "weight") and Heavy Armor, but none of it seemed to work better. 99. . In order to maximize their chance of winning, both the attackers and defenders employed trebuchets to help their cause. For an indoor trebuchet, you can use 1 x 6-inch (2.5 x 15 cm) planking. 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. 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. The trebuchet made improvements upon both of these weapons, able to launch stones that weighed hundreds of kilograms farther and more accurately than either the ballista or the catapult. Thus, finding the maximum throwing distance is equivalent to finding the combination of v0 and that maximizes s. Intuitively, you might think that the angle of release should be = 45. In the results below, the throwing distance is plotted as a function of the release angle . Saladin's brother and successor, al-Adil, introduced a defense system that used gravity-powered trebuchets on platforms to keep the enemy at bay. The animation below shows the motion of the trebuchet as it is fired. In use for almost 1000 years, the medieval version of the Chinese trebuchet transformed the battlefield thus changing the world forever. 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). The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. The traction trebuchet, which was a rather simple design were the force for firing was provided by men pulling down ropes. 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. 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 much smaller catapults used at the time were nowhere near as powerful but, not requiring contacting with the earth (to generate its power) was able to be put on wheels and move to where it was needed, unlike the trebuchets that were built on the location that they were needed and would need to be deconstructed before being moved. As an Amazon Associate I earn from qualifying purchases. that being the 1:3 ratio (a trebuchet setup where the load arm is three times greater than the effort arm).

The FAKA is very efficient for its frame height and arm length as well. measuring, and the axel connection. The frame supports all the other parts, and . The counterweight should be 75 to 100 times the weight of the projectile. To fix 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. 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 . A heavy counterweight hangs on the short end of the beam. Powered by STLFinder search engine. This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. It is a hinged counterweight trebuchet in which the counterweight hanger is placed on the top of the arm and the arm is pointed in the forward throwing direction when cocked. - Algorithms of a trebuchet, http://www.legionxxiv.org/trebuchetpage/ A neat pile of stone ball trebuchet ammunition recovered from the moat at Pevensey Castle SOURCE: geography.org.uk via Michael Garlick (Copyright). A small-scale replica of War Wolf, a counterweight trebuchet that uses a boulder-holding sling at the end of a swinging arm. A large counterweight trebuchet. 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. as it ends up shaking around on the A trebuchet built for engineering class.

Yet, this depictions seems to be a big over exaggerated. I designed the basket for 4x1 oz car wheel weights. Your arms will float up from your sides, as if lifted by an external force. 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. [12] J. Vaughan. This cookie is set by GDPR Cookie Consent plugin. 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.

What is the best ratio for a trebuchet? 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. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. What is the best ratio for a trebuchet? In this blog post, we will build a simplified model of a counterweight trebuchet using the Multibody Dynamics Module and examine some of its design features.

(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) 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. 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. Without a subpoena, voluntary compliance on the part of your Internet Service Provider, or additional records from a third party, information stored or retrieved for this purpose alone cannot usually be used to identify you. Another error that could have occurred was the axle [3] If you want to launch items of various weights, you can set up your trebuchet with a bucket or bag to hold and adjust the counterweight. . General advice is that the optimal ratio is 133:1. Analytical cookies are used to understand how visitors interact with the website. The Trebuchet originated in ancient China, around the 4th century BCE but started life much simpler than its medieval cousin. There are basically two types of trebuchets, the traction trebuchet, which was operated by men pulling ropes and the counterweight trebuchet, which provided the necessary force by using a counterweight.

A trebuchet is a type of catapult that uses a counterweight to engage the armwhich is attached to a slingand launch projectiles. 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 appeared in both Christian and Muslim lands around the Mediterranean in the 12th 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. Figure 2, below, shows a diagram of a trebuchet with the main parts labeled. The Traction Trebuchet is a siege weapon in Age of Empires IV that is unique to the Mongols. Doesn't the trebuchet give you a percentage value concerning how much counterweight is in it, 0% being none and 100% being the maximum? Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. Assembly video: in measurements that we had was in the timing. (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. The cookies is used to store the user consent for the cookies in the category "Necessary". [5] Wikipedia. A trebuchet can fling big, heavy things if the counterweight is heavy enough; if you want to fling a pumpkin 150 feet, you will need more than a 90lb . On a trebuchet, it's much closer to the counterweight. 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! 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. 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. John France notes: 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. Bernhard Kast is a participant in the Amazon EU Associates Programme, an affiliate advertising programme designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.co.uk. in Electrical Engineering from the University of Southern California. Do you have time to do a fancy design, or do you need to build one quickly? For centuries, the trebuchet was the most powerful war machine in the world. It is assumed that it is a Chinese invention and made its way to Europe via the Arab world around the 9th century. Please enter a search term in the text box. Press J to jump to the feed. Next, press the "Simulate" button located under the inputs. Namely, the Warwolf. 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) Its currently set up for a 100:1 counterweight to projectile mass ratio, with 200lbs of counterweight. Now, the number of ropes in the illustration is not correct, they were usually around 40 to 125 ropes and pulled by 40 to 250. 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. Some knowledge of physics will be helpful when doing this project. The force that the catapult needed to launch the projectile came from the manipulation of twisted ropes [3]. In this blog post, we demonstrated that the Multibody Dynamics Module can be used to build a simple model of a counterweight trebuchet. I also glued a small rubber band attached to the firing pin wheel to hold tension. The projectile is inside a pouch hanging on a sling attached to the long end of a balancing beam. 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) 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! released and stopped it when it landed, which could have been 60 M away. - user21033 Mar 24, 2013 at 16:03 Add a comment 0 The trebuchet was preferred over a catapult due to its greater range capability and greater accuracy. Which brings us to the next point, the overall effectiveness of trebuchets. One nonfictional and historically notable trebuchet is War Wolf (known to the English soldiers at the time as Ludgar). The counterweight is usually very heavy and provides the mechanical force to fire. Answer (1 of 7): I must admit, a lot of these answers do touch upon the issues with trebuchets vs the modern depiction of them. 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. Thanks. So it's easier now to fill it with anything you want. ground, 6. The weight of the counterweight must be much greater than 10 times. This cookie is set by GDPR Cookie Consent plugin. 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? (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 277-278) Whereas another scholar notes that modern replicas suggest a range in the order of only 100-120 m, which would be about the same as the traction trebuchet. recommend you keep the infill high for the pegs, and decently high for the legs, arm, and base. The FAKA is a trebuchet design invented in late 2006 by Craig Macomber. Levers provide a fixed movement ratio between the projectile end of the arm and the CW end of the arm. 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]. These improvements helped the trebuchet maintain dominance on the battlefield. The graph displays the range of projectile as the y-axis and the ratio as the x-axis. The counter-weight arm of the seesaw is usually shorter than the projectile arm by a ratio of 4 to 1 or more. . L2 is the distance between the pivot and the sling's attachment point (m). Pieces: 166+ pcs Assembly Time: 4h Assembled Size: 14.9x7.8x8.2 in Recommended Age: 14+ Material Description (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) Not only coins =) Video https://youtu.be/jpWVBItSfHg And I highly recomend to use this ajustable hook https://www.thingiverse.com/thing:2554790. 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. This allows for the beam to rotate vertically through a wide arc (typically over 180). Edit Rate (0) Tags Discuss History Files . (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 284) Thus, counterweight trebuchets with hard stones were probably used against fortifications, whereas traction trebuchets were used to attack softer targets like buildings. 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 . 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. The counterweight is cast concrete, 8 inches wide, 15 inch radius from the pivot hole to the curve of the concrete, 108 pounds total. Here, we build a computational model of a basic trebuchet with the Multibody Dynamics Module and version 5.3 of the COMSOL Multiphysics software. Yet, Hill notes that without the addition of a long sling, there was no possible combination that would have made it feasible weapon. This is probably the most exciting part of investigating how trebuchets work: actually building one! We launched pumpkins and bowling balls around 10-15 lbs at distances of 300+ feet. . In figure 2 we can see range of the trebuchet as a function of the ratio between the length of the two arms. Trebuchet Mechanics Donald B. Siano [email protected] 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.

Has been printed on a MiniFactory and works almost out of the box, some filing or sanding requred. 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. holes for our first axle and had to change the axle when the first one that we Trebuchet with variable arm ratios, 2. The trebuchet is a large siege weapon that you might recognize from movies set in the Middle Ages or fantasy worlds. The main beam, counterweight box, sling, projectile, trough, windlass, and framework are all clearly visible with dimensions given for some of the component parts. Now, since we covered that part, lets get started. [11] Ripcords Trebuchet Stuff. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 119) Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. The ratio between the counterweight and the payload is important, and this may dictate the size of your trebuchet. 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. Larger trebuchets would have large 'hamster' style wheels on the side of them, allowing men to run inside them to winch down the large arm where the projectile would be added, a pin would then be removed throwing the large arm upwards. 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. and still have enough energy to throw the projectile at a high velocity. many timing errors. Three parts. Launches 25 feet. Adult supervision is required when building and operating a trebuchet. Yet, the highest given number in the records was up to 1200 men, which sounds ludicrously high. 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. 24 dimes should be placed in the counterweight. Our model uses the following assumptions and physical dimensions: A schematic of the counterweight trebuchet model. 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. The main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. Lets see if this holds true for the trebuchet model. 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. 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. The cookie is used to store the user consent for the cookies in the category "Analytics". This happened From what we know it seems that counter-weight trebuchets were used with heavier missiles. The simplest trebuchet is basically a throwing arm pivoted on a fulcrum. Licensed under CC BY 3.0, via Wikimedia Commons. Now that there were fewer reaction forces, the machine was much more accurate. Since the middle ages, however, engineers have developed newer, more efficient styles of the trebuchet. 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. 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. This consent may be withdrawn. So, basically, not. The person who was timing started the watch when the projectile was between leverage and speed of the arm to achieve the highest velocity. An easier way to answer this is 'what didn't they throw'. Is a full counter weight of 100 stone stacks the max power/range of the Treb? 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]. 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. The main advantages of the counterweight trebuchet were its ability to fire larger stones and require less manpower during operations. The first of these, a "black box" model in which the mechanism for the Kaffa was a port city, so the disease soon spread across the Mediterranean and into European ports [3]. . Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. Figure 3: Trebuchet on the grounds of Caerlaverock Castle, Scotland. You can vary the weight on the back easily by putting more or fewer rocks inside. 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? Bernhard Kast is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com. 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. https://www.thingiverse.com/xbxbxb123/designs, For the Trebuchet, I work on the counterweight and the fire arm. Create an account to follow your favorite communities and start taking part in conversations. There are other accounts for other sieges giving a value of about 250 kg (560 lbs). 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. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 119; Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 271-272) It was the dominant form of artillery in Western warfare during the period of 1000 to 1300 AD. (Weights) - https://www.amazon.com/gp/product/B07XBB4WX6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. The Chinese invented the trebuchet in 300BC, the French were . 3).
