trebuchet counterweight ratio

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) 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! Can you pick these parameters based on hand calculations or computer simulations (above), or based on design information you found through your own research? because at 5:1, there was not enough power to lift the arm and the projectile 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? Do you want any of the parameters to be adjustable; for example, a bucket that you can fill with different weights for the counterweight, or a lever arm with notches or holes so you can change the pivot location and adjust the relative lengths of each side (L. The hinge greatly increased the efficiency of the motion involving the counterweight, causing more power to be delivered to the projectile. [12] J. Vaughan. Gurstelle once made a large trebuchet with a 500-pound (226-kilogram) counterweight that was still only powerful enough to launch a small cantaloupe. This cookie is set by GDPR Cookie Consent plugin. This cookie is set by GDPR Cookie Consent plugin. Some of this energy (not all) will be transformed to kinetic energy of the projectile. Some errors that we had in measuring could have happened because we laid the meter tape on the ground in a stationary position and no matter how far to and don't have more than a 1:45 ratio of object mass to counterweight mass. Lets see if this holds true for the trebuchet model. of your trebuchet be? This cookie is set by GDPR Cookie Consent plugin. What are the advantages of a floating arm trebuchet? 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. Do you have time to do a fancy design, or do you need to build one quickly? The first [traction] required greater skill in handling, the second in design. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 279) weights from Dick's Sports for $6.99 a piece. A contemporary image of a trebuchet being loaded SOURCE: medievalists.net. 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? Youll need to cut 8 pieces: Two long base pieces. This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. 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 . Do you need to build a miniature trebuchet that fits on a tabletop? 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 . (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123). How much counterweight does a trebuchet need? Christopher Carrillo was born in Monterey Park, CA. CW stands for counterweight, and the release . Trebuchet (My version) New axes and counterweight, new printable axes, and modified the counterweight. These cookies track visitors across websites and collect information to provide customized ads. The counterweight is usually very heavy and provides the mechanical force to fire. Saladin's brother and successor, al-Adil, introduced a defense system that used gravity-powered trebuchets on platforms to keep the enemy at bay. Not only does the sling add firing distance to the trebuchet, it gives the crew manning the trebuchet the ability to aim. In addition to unequal weights, the trebuchet uses leverage. It will take 1-2 iron reinforcements to repair it back up to 2500 health after each boulder. 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. Since they could be mounted on towers they would also outrange the attackers machine. 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. The floating arm trebuchet uses a counterweight held on top of a tall drop channel to transfer potential energy into kinetic energy. (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: Trebuchets may be dead on the battlefield, but they are still very much alive in the hearts of students and hobbyists who take joy in discovering the workings of these amazing machines. A build it yourself trebuchet! The ratio of the mass of the counterweight to the mass of the payload, expressed as CW:P. A typical MR is 100:1. sometimes sliding around. To further analyse this phenomenon I have created another graph that keeps a constant counterweight mass and but changes the ratio. 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 . Whereas the traction trebuchet had the force only applied for a short amount of time. - user21033 Mar 24, 2013 at 16:03 Add a comment 0 too much ballast can result in wasted energy and machine wear. Whatever you decide you want to launch with your trebuchet, your counterweight should be from 100 to 133 times the weight of your projectile. These cookies will be stored in your browser only with your consent. 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. 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. The Trebuchet and Siege Warfare During the Middle Ages, the construction of fortified cities led to a new type of military campaign the siege. There is more than one way to tackle the problem. 2 stacks of fire arrows are the same. The arm then jerks forward and releases the projectile from the sling. A trebuchet is made of a long beam attached by an axle suspended high above the ground by a stout frame and base.

Bernhard Kast ist Teilnehmer des Partnerprogramms von Amazon Europe S..r.l. 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. How closely do they match? 99. . 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. in measurements that we had was in the timing. 2020 by History University. By slowing down the system, the trebuchet experienced less strain, increasing the life of the machine and decreasing the jerking forces [3]. Record the distance and time on a piece of paper, 8. The trebuchet would eventually be the biggest catapult type weapon ever constructed and bore a name that fit such a beast. I would recommend bring at least 2-300 . [13] History Forum. The range of a trebuchet has always been important. Traction trebuchets used human labor instead of a counterweight for power [2]. 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. The counterweight is raised and the trebuchet is cocked. I was able to use the collars from my weight set to hold the weights as they were slightly bigger than 1". He forced the Scots to remain inside the castle and restarted his siege. 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). Some of these references contain advanced math, including calculus and differential equations, but you can still use them to help you get started. The fixed counterweight eventually gave way to a hinged counterweight (Fig. But the usual weight was probably more around 45 to 90 kg (100 to 200 lbs). The projectile undergoes a swinging motion and is released at some suitable position along its trajectory. Hill states about the Counterweight Trebuchet: First, tape the AA battery to one end of a popsicle stick. Internet: http://www.ripcord.ws, [Oct. 11, 2006]. "Effect of Trebuchet Arm Length or Counterweight Mass on Projectile Distance.". 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. The Trebuchet works functional but the connection between each parts seems weak and need to be improved. these errors, we could test it on a less windy day, be more careful timing, and I also glued a small rubber band attached to the firing pin wheel to hold tension. An easier way to answer this is 'what didn't they throw'. 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. 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. Drill a small hole into the back end of the swing arm about 1 inch (2.5 cm) from the end. 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. 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 . 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. The A trebuchet a simple machine from the middle ages when attacking the opposing side. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 121) Something that was not the case with the Counter-weight Trebuchet, so lets take a closer look at it. It is assumed that the usage of heavy missile throwers was far greater in siege warfare in the Middle East than in Western Europe. Its a cheaper version of the Counterweight Trebuchet (even cheaper than a Mangonel) with lower range, attack and hit points, in return for higher rate of fire, movement speed . The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. The hinge also helped to slow down the system when it reached the bottom. Ideally a ratio of around 100/1 ballast to projectile weight should be used, this results in . und Partner des Werbeprogramms, das zur Bereitstellung eines Mediums fr Websites konzipiert wurde, mittels dessen durch die Platzierung von Werbeanzeigen und Links zu amazon.de Werbekostenerstattung verdient werden knnen. 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. You can print every part with standard settings. Here is an oversimplified diagram of an armed trebuchet. For an outdoor trebuchet, you can use 2 x 4-inch (5 x 10 cm) planking. From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). How much space do you have to test your trebuchet? 2). Unbend one end of a paper clip so it is almost, but not quite, straight. The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. 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. The working principle of a trebuchet is simple. Model Trebuchet can be made using Stripwood Technology techniques with card and 8mm x 8mm square timber. Repeat steps 4 8 for all ten settings. What is the best ratio for a trebuchet? The ballista eventually gave way to the catapult [3]. Where should the pivot point be on the beam? 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? These super weapons are the result of over two millennia of trial and error that began with the development of the trebuchet. 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. Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. [5] Wikipedia. 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 cookie is used to store the user consent for the cookies in the category "Analytics". 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. Hurl those stones. 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. 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) 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. Which brings us to the next point, the overall effectiveness of trebuchets. in Electrical Engineering from the University of Southern California. 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). https://youtu.be/5RZazivVX7k We launched pumpkins and bowling balls around 10-15 lbs at distances of 300+ feet. h is the initial height of the counterweight off the ground. Figure 3, below, shows a sketch that can help you start thinking about how to set up the problem, and the variables involved. The same counterweight but without supports.

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. (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). Press J to jump to the feed. I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. When assembled it has an internal capacity of 2600ccs. 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. Two of the major predecessors of the trebuchet were the ballista (Fig. Every city occupied by Mongols in Central . Mold is made of two plywood arcs with holes at the center. Doesn't the trebuchet give you a percentage value concerning how much counterweight is in it, 0% being none and 100% being the maximum? The sheer size and potential destructive force, forced a well supplied garrison to give up on an incredibly important castle, showing just how dangerous trebuchets could be. Less tunable than HCW trebuchets at high ratios. L3 is the length of the sling (m). 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. Any questions? Now, lets examine what happens if we modify the length of the sling by 10% using a parametric sweep. I assume if one includes maintenance into handling that the counterweight trebuchet was harder to handle. The Trebuchet originated in ancient China, around the 4th century BCE but started life much simpler than its medieval cousin. This counterweight was affixed to the end of the shorter arm and, without the need for ropes and people to pull the machine, space was available for lengthening the sling, which allowed the projectile to go even farther [3]. These cookies ensure basic functionalities and security features of the website, anonymously. Launches 25 feet. Edit Rate (0) Tags Discuss History Files . The counterweight should be 75 to 100 times the weight of the projectile. The main advantages of the traction trebuchet were that it was faster and cheaper to build and needed no specialists, unlike the counterweight trebuchet. wind could have caused us errors by blowing our projectile off to one side, Levers provide a fixed movement ratio between the projectile end of the arm and the CW end of the arm. holes for our first axle and had to change the axle when the first one that we How long should the arm of a trebuchet be? 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. Try for yourself by downloading the model file from our Application Gallery. 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. Kaffa was a port city, so the disease soon spread across the Mediterranean and into European ports [3]. The main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. $8.95Skeletal Army - Counterweight Trebuchet. When the counterweight is raised up, it has lots of gravitational potential energy. Bernhard Kast is a participant in the Amazon.com.ca, Inc.

L1 is the distance between the pivot and the counterweight's attachment point in meters (m). Enjoy! Our team of volunteer scientists can help. 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 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. John France notes: The Floating Everything Trebuchet (FET) - a poor man's FAT, without the vertical guides. Please note: This post contains amazon affiliate links. The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. The relation in length for the long and short parts of the beam was 6:1 or 5:1 for light machines and 2:1 or 3:1 for heavy traction trebuchets. 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. https://www.thingiverse.com/xbxbxb123/designs, For the Trebuchet, I work on the counterweight and the fire arm.

A trebuchet has a lever arm with a large, heavy counterweight on one end and a smaller projectile on the other end. In use for almost 1000 years, the medieval version of the Chinese trebuchet transformed the battlefield thus changing the world forever. This consent may be withdrawn. A neat pile of stone ball trebuchet ammunition recovered from the moat at Pevensey Castle SOURCE: geography.org.uk via Michael Garlick (Copyright). War Wolf proved its worth, and the rest is, as they say, history. I made a "trigger" for the catapult out of two big shackles and a rod . Furthermore, Hill assumes that light trebuchets were used to throw missiles into the city, whereas the heavy trebuchets were used for attacking the walls. Chinese Siege Warfare: Mechanical Artillery & Siege Weapons of Antiquity An Illustrated History Internet: http://authors.historyforum.com/liang_jieming/chinesesiegewarfare>. Lets begin with the traction trebuchet, which is an older and simpler design. [Siege of Acre (1189-1191)]. You also have the option to opt-out of these cookies.
