trebuchet counterweight ratio

Figure 2, below, shows a diagram of a trebuchet with the main parts labeled. [4] Trebuchet.com. Modified counterweight to allow for other ballast other than coins. While they are no longer used in warfare, today people still build trebuchets for fun and use them in contests to see who can launch things the farthest. The goal of this project is to determine how different physical parameters can affect the range of a trebuchet, using hand calculations, computer simulations, and/or physical experiments. Enjoy! could be altered, the idea behind the trebuchet was that the counterweight could bring the projectile full circle for a greater arc and therefore a greater throwing distance and force. Not consenting or withdrawing consent, may adversely affect certain features and functions. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123-124; Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 275-279). Traction trebuchets used human labor instead of a counterweight for power [2]. (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. We launched pumpkins and bowling balls around 10-15 lbs at distances of 300+ feet. http://www.io.com/~beckerdo/other/trebuchet.html - Plans and directions for building a small trebuchet, http://www.tbullock.com/trebuchet.html (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 119) Our team of volunteer scientists can help. General advice is that the optimal ratio is 133:1. Proudly created with Wix.com, Weapons That Changed The World: The Counterweight Trebuchet, 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. The counterweight is cast concrete, 8 inches wide, 15 inch radius from the pivot hole to the curve of the concrete, 108 pounds total. To begin, enter the parameters of your trebuchet in the input boxes. The curves shows the best ratio between the arms to be 2.3 : 1 no matter what the length of the counterweight arm within the range 0.321 - 0.5 m considered for my needs. 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. In use for almost 1000 years, the medieval version of the Chinese trebuchet transformed the battlefield thus changing the world forever. Note: A trebuchet utilizes specific measurements to throw a projectile using the power of a falling weight. General advice is that the optimal ratio is 133:1. The power delivered to a wall from a device like this could be incredibly devastating. But opting out of some of these cookies may affect your browsing experience. Is there anything heavier than a 100 stack of stone (13.00 "weight") that can be used as a counter? In movies and computer games Trebuchets are often shown as weapons that can destroy city walls and towers easily. guessed the distance. With Just a trebuchet frame and swing arm ready to print. Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. and still have enough energy to throw the projectile at a high velocity. 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. One can expect that only a limited number of these special stones were available and used. 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. Anyone who has played Age of Empires (this includes me, yes), will know exactly what a trebuchet is, and what it does. Levers provide a fixed movement ratio between the projectile end of the arm and the CW end of the arm. The weight of the counterweight must be much greater than 10 times. A trebuchet is a type of catapult that uses a swinging arm to throw a projectile. Required fields are marked *. These super weapons are the result of over two millennia of trial and error that began with the development of the trebuchet. A trebuchet is a medieval stone-throwing war engine. These cookies will be stored in your browser only with your consent. The Traction Trebuchet is a siege weapon in Age of Empires IV that is unique to the Mongols. The Trebuchet works functional but the connection between each parts seems weak and need to be improved. 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. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. be 3:1 and not 5:1. 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]. Launches 25 feet. Necessary cookies are absolutely essential for the website to function properly. This allows for the beam to rotate vertically through a wide arc (typically over 180). 6 What are the advantages of a floating arm trebuchet? Which is correct everyone do or everyone does? 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. 4.4 4.4 out of 5 stars (13) $32.99 $ 32. 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]. Figure 3, below, shows a sketch that can help you start thinking about how to set up the problem, and the variables involved. You also have the option to opt-out of these cookies. 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. Read the relevant section(s) below for ideas on how to get started on your project. L4 is the length of the rope suspending the counterweight (this distance is zero if the counterweight is fixed directly to the lever arm) (m). Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. The first of these, a "black box" model in which the mechanism for the So it's easier now to fill it with anything you want. I assume if one includes maintenance into handling that the counterweight trebuchet was harder to handle. 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. A trebuchet (French trbuchet) is a siege engine used in the Middle Ages. wind could have caused us errors by blowing our projectile off to one side, This happened (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: 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. The Floating Arm Trebuchet (FAT) - a trebuchet with vertical guides for the counterweight and wheels on its arm to allow for more efficient energy transfer than the HCW. connection. 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. Set out a meter tape starting from the front of the base and lay on Trebuchet. Internet: http://en.wikipedia.org/wiki/Trebuchet, [Oct. 11, 2006]. 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 cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. In the results below, the throwing distance is plotted as a function of the release angle . This consent may be withdrawn. of the sides twice. Before the addition of the sling, the crew had to move the entire trebuchet to change the direction of the trajectory. Pictures. What tools and safety equipment do you have access to? The further between . [12] J. Vaughan. [5] Wikipedia. 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. Is a full counter weight of 100 stone stacks the max power/range of the Treb? 1) and the catapult [1]. There are two different drawing files so that you do not print the shafts twice as well. 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. The The longer end of the beam would hold the projectile while the shorter end would hold a counter weight [2]. As the projectile is swung around by the swinging arm, it describes a nontrivial motion of varying velocity. The earliest trebuchets were traction trebuchets [which] were invented in China in the 5th 3rd centuries B.C.E. [6]. The trebuchet is the hallmark of medieval siege warfare and is synonymous. Trebuchet counterweight? The traction Trebuchet or Mangonel, which was adopted by the Byzantine empire some 100 years after their first recoded use in China, relying on man power to pull ropes and weights to thrown the projectile via the long swinging arm, a very time consuming and some what . 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! On a trebuchet, it's much closer to the counterweight. A f2k trebuchet has an arm that rides on wheels, which roll forward on rails, while the weight bar running through the arm falls down in a vertical groove. 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. Press J to jump to the feed. [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. 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. How much counterweight does a trebuchet need? A trebuchet works by using the energy of a falling (and hinged) counterweight to launch a projectile (the payload), using mechanical advantage to achieve a high launch speed. This makes sense intuitively since range is a key factor when staging an attack on an enemy. How does the mass and height of the counterweight affect the trebuchet system? Unbend one end of a paper clip so it is almost, but not quite, straight. For a sling, I use the handle from a plastic grocery bag. He forced the Scots to remain inside the castle and restarted his siege. The projectile undergoes a swinging motion and is released at some suitable position along its trajectory. 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 . 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? Finally, watch your trebuchet go. 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. Science Buddies Staff. 2020 by History University. 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 projectile goes much farther than the counterweight in the same amount of time, which means that it moves a lot faster than the counterweight. But the question of the exact provenance of the invention, whether in Europe or in Islam, is not resolved. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 275-276). The variables in Figure 3 are as follows: How can you use these variables to calculate the range of 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. Not only coins =) Video https://youtu.be/jpWVBItSfHg And I highly recomend to use this ajustable hook https://www.thingiverse.com/thing:2554790. But John France notes: This advancement, allowed more consistent fire, longer distances and thus, more destruction. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet. Powered by STLFinder search engine. The main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. 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. Also, the newfound stability meant that the trebuchet did not have to be repositioned after every shot, so firing time improved to about twice per hour [6]. Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. Can you make a trip to the hardware store and build your trebuchet with wood, nuts, and bolts? Gurstelle once made a large trebuchet with a 500-pound (226-kilogram) counterweight that was still only powerful enough to launch a small cantaloupe. Repeat steps 4 7 to get two more trials on this arm ratio setting, 9. Counterweight is filled with spare change. explanatory. (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) The floating arm trebuchet uses a counterweight held on top of a tall drop channel to transfer potential energy into kinetic energy. 1 The purpose of this paper is to explain the basic functions of a trebuchet, explain subsystems of the trebuchet, and give examples of a few possible modifications to the subsystems. 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. Of course, the hanging CW trebuchet sacrifices counterweight fall distance for this efficiency. . Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. However, you may visit "Cookie Settings" to provide a controlled consent. There is more than one way to tackle the problem. The main beam, counterweight box, sling, projectile, trough, windlass, and framework are all clearly visible with dimensions given for some of the component parts. Lets see if this holds true for the trebuchet model. (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. In terms of operating, it depends to a certain degree on the perspective, which one was, Hill notes the following: Why is it a complicated design? [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]. Trebuchets were still being used well into the 16 century CE, even though gunpowder weapons had been fairly common on European battle fields for around 100 years. When assembled it has an internal capacity of 2600ccs. 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. Since they could be mounted on towers they would also outrange the attackers machine. Furthermore, a mechanism for pulling down and fixating the long arm was added, which was usually a winch. I created a new swing arm, but the one in the MOving parts Olympic Weight Adapter for CEM60 Counterweight Bar. 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. I was able to use the collars from my weight set to hold the weights as they were slightly bigger than 1". The ratio between the counterweight and the payload is important, and this may dictate the size of your trebuchet. Bernhard Kast is a participant in the Amazon.com.ca, Inc. Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.ca. The plot reveals that deviations of the order of 5 from this optimum only affect the throwing distance by a few meters. To throw the payload as far as possible, how long should the beam be? 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]. (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. Figure 1, below, shows a modern reconstruction of a trebuchet. 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. Do you need to use household materials like cardboard, duct tape, and string? Lets begin with the traction trebuchet, which is an older and simpler design. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet, I rebuilt this Trebuchet design in Rhino, made it easier to 3d print. 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. Hurl those stones. 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. 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! with European battles from England to the balkans. The catapult operator would twist ropes that surrounded the pivoting arm, causing immense tension. What about moments of inertia, which are not labeled in Figure 3? 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. This cookie is set by GDPR Cookie Consent plugin. The plot below shows that the maximum throwing distance that can be obtained is greatly affected by the length of the sling. It will take 1-2 iron reinforcements to repair it back up to 2500 health after each boulder. 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. All of the parts required to assemble one Trebuchet counterweight. Attach the remaining flat part of the paper clip to the other end of the popsicle stick, with the straightened part pointing outward and up (away from the counterweight). The results from this were lackluster. Hill states about the Counterweight Trebuchet: Science Buddies Staff. Simplest of all trebuchet designs mechanically. [7] Encyclopedia Britannica. Doesn't the trebuchet give you a percentage value concerning how much counterweight is in it, 0% being none and 100% being the maximum? Christopher Carrillo was born in Monterey Park, CA. The machine is generally associated with hurling boulders at a castle wall to bring it down, but trebuchets have also been used to throw Greek fire and wreak all kinds of havoc. 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.
