How much time do you have to build your trebuchet? If you are interested in learning more about multibody dynamics modeling, check out these additional blog posts: Wondering why War Wolf was also called Ludgar? Record the distance and time on a piece of paper, 8. If you search online, there are many different plans and designs for building a trebuchet. These super weapons are the result of over two millennia of trial and error that began with the development of the trebuchet. L1 is the distance between the pivot and the counterweight's attachment point in meters (m). War Wolf proved its worth, and the rest is, as they say, history. Powered by STLFinder search engine. The technical storage or access that is used exclusively for statistical purposes. 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) This allows the longer projectile arm to move 4 times as far for each . 2020 by History University.

Read the relevant section(s) below for ideas on how to get started on your project. I chose the most obvious coordinate system, using three angles, but perhaps a Cartesian system is easier. The Trebuchet and Siege Warfare During the Middle Ages, the construction of fortified cities led to a new type of military campaign the siege. [11] Ripcords Trebuchet Stuff. Reproduction of material from this website without written permission is strictly prohibited. Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare 1000-1300. The pivoting arm would then stop and the projectile would be flung forward. The optimal trebuchet design is one that launches the payload the farthest horizontal distance. Never "dry fire" the trebuchet - always load a projectile to balance the firing mechanism. 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! (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. Two of the major predecessors of the trebuchet were the ballista (Fig. In either case, can you make your analysis more realistic by accounting for things like friction and air resistance? Read the documentation or contact us.
The range of a trebuchet has always been important. Press J to jump to the feed. Volleyball Design and How Volleyball Designs Affect the Game, How to Engineer a Record-Breaking Swimsuit, To the Beginning of Time: NASAs Journey to Uncovering the Past, Diverting Away from the Steel Age: Metallurgy Reimagined in the Context of the Climate Crisis. A trebuchet is made of a long beam attached by an axle suspended high above the ground by a stout frame and base. A heavy counterweight hangs on the short 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 . (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. Because we drilled the
From what we know it seems that counter-weight trebuchets were used with heavier missiles. Here is an oversimplified diagram of an armed trebuchet. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 120). Is a full counter weight of 100 stone stacks the max power/range of the Treb? Once the arm was in place, the projectile would be loaded into a cup at the end of the arm. In the fall of 2005, he was pursuing a B.S. 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 . m1 is the mass of the counterweight in kilograms (kg). 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. They stood as tall as 60 feet (18m) and could fling 80 pound (36kg) objects up to 980 . Copyright 2002-2023 Science Buddies. the side of the tape the projectile landed, we just looked at the meter tape and
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. 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. A 1:1 sling length to throwing arm ratio builds up the best amount of speed for the projectile. 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. m2 is the mass of the payload (kg). [12] J. Vaughan. Three parts. https://youtu.be/Hb05YVnp0Tw. Yet, one would assume that proper calculations or laborious trial and errors of various variations could produce an effective counterweight-trebuchet. When assembled it has an internal capacity of 2600ccs. 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. Military History Visualized Offical Homepage for the YouTube Channel. 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. They were created for a terrible purpose, but they're also an amazing example of human ingenuity. 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. 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. 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. 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. 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. Military History Visualized subscribestar, Military History Visualized Merchandise. (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.
By the way if the concept of the traction trebuchet is too odd for you, you might check out the following real life video of one and for those who want to rebuild one in the sandbox game besiege, there is also at least one video. 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) Mold is made of two plywood arcs with holes at the center. holes for our first axle and had to change the axle when the first one that we
The power delivered to a wall from a device like this could be incredibly devastating. 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. The catapult consisted of a solid base with a pivoting arm that would be pulled down and locked into place [1]. (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. All of the parts required to assemble one Trebuchet counterweight. Licensed under CC BY 3.0, via Wikimedia Commons. Now you will build the trebuchet's arm. This cookie is set by GDPR Cookie Consent plugin. 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). Note: A trebuchet utilizes specific measurements to throw a projectile using the power of a falling weight. I needed about 5 lbs so I used 2 plates and adapters and cable-tied them together. A contemporary image of a trebuchet being loaded SOURCE: medievalists.net. The projectile undergoes a swinging motion and is released at some suitable position along its trajectory. When the counterweight is raised up, it has lots of gravitational potential energy. Edward I of England, who had spent months battering the walls of the castle with massive stone and lead projectiles, was becoming sick of the siege going nowhere. Ideally a ratio of around 100/1 ballast to projectile weight should be used, this results in . The sling is attached to the end of the long arm of the lever. Feed some string through the hole and tie the bucket in place. In movies and computer games Trebuchets are often shown as weapons that can destroy city walls and towers easily. The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. Enjoy! 6 What are the advantages of a floating arm trebuchet? This created an increase in falling distance and centrifugal force, both of which contributed to greater power. Your arms will float up from your sides, as if lifted by an external force. 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. A small-scale replica of War Wolf, a counterweight trebuchet that uses a boulder-holding sling at the end of a swinging arm. Whereas the traction trebuchet had the force only applied for a short amount of time. What experience do you need to become a teacher? What are the advantages of a floating arm trebuchet? This massive weapon was eventually capable of throwing massive boulders over 250 meters, but it did not start that way. 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. Another error that could have occurred was the axle
[7] Encyclopedia Britannica. [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]. The maximum throwing distance is obtained if the projectile is released at 38. The main advantages of the counterweight trebuchet were its ability to fire larger stones and require less manpower during operations. When the catapult was released, the ropes would twist back into shape and swing the pivoting arm upward until it reached a vertical position and hit a cushioned pad. 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! 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. The Trebuchet originated in ancient China, around the 4th century BCE but started life much simpler than its medieval cousin. Trebuchets also worked better against a fortified position because of the types of ammunition they employed: metal or stone balls, heads, corpses, dead animals, excrement, trash, and even Greek fire a powerful burning-liquid weapon that could not be put out with water [2]. The FAKA is a trebuchet design invented in late 2006 by Craig Macomber. Analytical cookies are used to understand how visitors interact with the website. Is there anything heavier than a 100 stack of stone (13.00 "weight") that can be used as a counter? Ancient Weapon Inspires Student.. Our hypothesis was not supported because the optimum arm ratio seemed to
Furthermore, Hill assumes that light trebuchets were used to throw missiles into the city, whereas the heavy trebuchets were used for attacking the walls. General advice is that the optimal ratio is 133:1. The FAKA is very efficient for its frame height and arm length as well. Lets begin with the traction trebuchet, which is an older and simpler design. 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. Christopher Carrillo was born in Monterey Park, CA. Which brings us to the next point, the overall effectiveness of trebuchets. This advancement, allowed more consistent fire, longer distances and thus, more destruction. Counterweight powered trebuchet where the counterweight is directly attached to the short arm. One is the frame, one is the swing arm, and one is the set of moving parts. Anyone who has played Age of Empires (this includes me, yes), will know exactly what a trebuchet is, and what it does. 1) and the catapult [1]. Any questions? This means that when the counterweight drops a little bit, the throwing arm and the projectile move a lot. . General advice is that the optimal ratio is 133:1. For an indoor trebuchet, you can use 1 x 6-inch (2.5 x 15 cm) planking. (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). Toystub Trebuchet Kit Puzzle 3D Wood Puzzle Wooden Models for Teen. The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1. 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. and still have enough energy to throw the projectile at a high velocity. many timing errors. Might want to attach something heavier to act as a counter weight. The counterweight is raised and the trebuchet is cocked. The Wikipedia page on trebuchets links to a PDF paper which discusses exactly this question. Overall, both types of trebuchets were used together during sieges. 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. 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. Less tunable than HCW trebuchets at high ratios. Trebuchet. Internet: http://en.wikipedia.org/wiki/Trebuchet, [Oct. 11, 2006]. Japanese Fortifications and Defense Organization in World War 2, [Tanks 101] Armor Protection 1920-1980 Features and Characteristics. Necessary cookies are absolutely essential for the website to function properly. It will take 1-2 iron reinforcements to repair it back up to 2500 health after each boulder. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional".

A trebuchet is a type of catapult that uses a swinging arm to throw a projectile. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 274 & 280). forcing the projectile out of the leather bag and onto the target. For a small trebuchet, you may want to make them 1 foot (30 cm) long; for a larger trebuchet, they can be longer. A trebuchet is a long-range weapon that uses a swinging arm to send a projectile toward a target. 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. You manually load it by placing the ammo on the trebuchet in the inventory menu, then place rocks in the counterweight section to determine how far the projectile will fly. 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. [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. When printing this document, you may NOT modify it in any way. The graph displays the range of projectile as the y-axis and the ratio as the x-axis. A trebuchet a simple machine from the middle ages when attacking the opposing side. Rolling wheels prevent the crushing lurch. 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. I would recommend bring at least 2-300 . https://youtu.be/5RZazivVX7k
VirtualTrebuchet is a web based trebuchet simulator that will allow you to quickly evaluate different trebuchet configurations. Figure 1, below, shows a modern reconstruction of a trebuchet. The ballista eventually gave way to the catapult [3]. Scrohammer happily hurls these wee glass spheres of doom a surprising distance of 40 feet. The catapult operator would twist ropes that surrounded the pivoting arm, causing immense tension. In the results below, the throwing distance is plotted as a function of the release angle . 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]. This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. Set out a meter tape starting from the front of the base and lay on
Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. Now, since we covered that part, lets get started. also different stuff as counterweight. Your email address will not be published. "Effect of Trebuchet Arm Length or Counterweight Mass on Projectile Distance.". This is why more than one wheel is used. 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. (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:
The same counterweight but without supports. For example, when I first shot my trebuchet I was using a 2.26kg payload and a 22.6kg counterweight. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. This is exactly as I predicted. The plot reveals that deviations of the order of 5 from this optimum only affect the throwing distance by a few meters. 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. 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. 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. 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. 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. . . 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. 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.
