CW stands for counterweight, and the release . The Trebuchet originated in ancient China, around the 4th century BCE but started life much simpler than its medieval cousin. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. It . Anyone who has played Age of Empires (this includes me, yes), will know exactly what a trebuchet is, and what it does. 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. With starting and stopping points this uncertain, there could have been Because we drilled the Construction . This allows the longer projectile arm to move 4 times as far for each .

(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). The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1. In addition to unequal weights, the trebuchet uses leverage. In this formidable weapon, the long end of an arm on a pivot was hauled or winched down and then released, allowing a heavy counterweight at the short opposite end of the arm to drop and swing the long end upward Why is it a complicated design? (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. 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. The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. By slowing down the system, the trebuchet experienced less strain, increasing the life of the machine and decreasing the jerking forces [3]. Or something in between? This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. The person who was timing started the watch when the projectile was Trebuchet Essay. sometimes sliding around. Christopher Carrillo was born in Monterey Park, CA. What are various methods available for deploying a Windows application? The Wikipedia page on trebuchets links to a PDF paper which discusses exactly this question. 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. Bernhard Kast ist Teilnehmer des Partnerprogramms von Amazon Europe S..r.l. Yet, during operations it needed a large amount of manpower. They stood as tall as 60 feet (18m) and could fling 80 pound (36kg) objects up to 980 . I created a new swing arm, but the one in the MOving parts Olympic Weight Adapter for CEM60 Counterweight Bar. 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. 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. 2 stacks of fire arrows are the same. 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. Catapulting Science Into Fun.. 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. In order to maximize their chance of winning, both the attackers and defenders employed trebuchets to help their cause. They work great over a huge range of mass ratios. Three parts. 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). 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. The graph displays the range of projectile as the y-axis and the ratio as the x-axis. Another error 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]. If you get stuck, you may need to consult a physics textbook, ask your physics teacher for help, or do your own internet search for "trebuchet physics." However, there have been occasions where trebuchets could reduce the wall to rubble in a few shots. This massive weapon was eventually capable of throwing massive boulders over 250 meters, but it did not start that way. All weapons have their pros and cons with the trebuchet having its fair share of both. 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. Adult supervision is required when building and operating a trebuchet. The working principle of a trebuchet is simple. Every city occupied by Mongols in Central . We tried 100x Ironstone ore (10.00 "weight") and Heavy Armor, but none of it seemed to work better. How closely do they match? The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network. A trebuchet is made of a long beam attached by an axle suspended high above the ground by a stout frame and base. 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. Medieval battlefields consisted mainly of sieges to fortified cities by some hostile force. 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. Furthermore, a mechanism for pulling down and fixating the long arm was added, which was usually a winch. 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. A contemporary image of a trebuchet being loaded SOURCE: medievalists.net. Its currently set up for a 100:1 counterweight to projectile mass ratio, with 200lbs of counterweight. 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. 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 . What is the best ratio for a trebuchet? The propped counterweight was very similar to the hinged counterweight, except the weight was forced to make an angle with the arm instead of hanging straight down. Hurl those stones. (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: 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). Powered by STLFinder search engine. listed if standards is not an option). For an outdoor trebuchet, you can use 2 x 4-inch (5 x 10 cm) planking. 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. To throw the payload as far as possible, how long should the beam be? Simplest of all trebuchet designs mechanically. 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. holes for our first axle and had to change the axle when the first one that we The fixed counterweight eventually gave way to a hinged counterweight (Fig. Trebuchet A siege engine for hurling heavy loads BuildingItem Health 5000 Container Size 15 Weight 50.00 Knowledge Engineer ID 89813 Engineer Recipe ID 89801 Level 25 Cost 3 Requires Teaches Siege Foundation A foundation for building siege equipment Crafted at Any carpenter's bench Trebuchet Base A rotating base for a trebuchet It is assumed that it is a Chinese invention and made its way to Europe via the Arab world around the 9th century. Furthermore, Hill assumes that light trebuchets were used to throw missiles into the city, whereas the heavy trebuchets were used for attacking the walls. The trebuchet was preferred over a catapult due to its greater range capability and greater accuracy. Your email address will not be published. While wood is easier to gather, it does consume more wood than reinforcements. 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! This cookie is set by GDPR Cookie Consent plugin. Read the documentation or contact us. They were created for a terrible purpose, but they're also an amazing example of human ingenuity. 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. This makes sense intuitively since range is a key factor when staging an attack on an enemy. Thus, sometimes stones were transported a long way: The trebuchet quickly became the Royal Mail of siege weapons, delivering virtually anything that would fit in its large leather pouch, from the afore mentioned large rocks to pile of dung or dead and decaying bodies, to scare and mentally beat an enemy. Since they could be mounted on towers they would also outrange the attackers machine. War Wolf proved its worth, and the rest is, as they say, history. What is the best ratio for a trebuchet? (2006, Oct. 12) Military Technology., [8] R. Meyer, Column One; How Far Can a Piano Fly?, [10] D. Moe. From what we know it seems that counter-weight trebuchets were used with heavier missiles. (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. Once you have derived an equation for the range of a trebuchet based on the physical parameters above, can you come up with any design guidelines or rules of thumb for designing a trebuchet with the best possible range? Try for yourself by downloading the model file from our Application Gallery. 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! Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. Less tunable than HCW trebuchets at high ratios. These references will be useful for learning about the physics of trebuchets. A large counterweight trebuchet. . 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]. Will allow to have fun in areas such as home and office, for children and adults. A trebuchet exists as a medieval rock throwing machine, but quite different to a catapult. 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. If you want to do hand calculations to design a trebuchet with the best range, you will need to understand the physics involved. . Whereas the traction trebuchet had the force only applied for a short amount of time. Some of these references contain advanced math, including calculus and differential equations, but you can still use them to help you get started. 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. These super weapons are the result of over two millennia of trial and error that began with the development of the trebuchet. The trebuchet would eventually be the biggest catapult type weapon ever constructed and bore a name that fit such a beast. At Acre, Richard used very hard stones brought from the West, which were so unusual that they were specially shown to Saladin. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 124) Figure 3: Trebuchet on the grounds of Caerlaverock Castle, Scotland. 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.

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. The counter-weight arm of the seesaw is usually shorter than the projectile arm by a ratio of 4 to 1 or more. 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. Despite the multitude of builds, very little has been published about. The traction trebuchet, which was a rather simple design were the force for firing was provided by men pulling down ropes. A trebuchet is a medieval stone-throwing war engine. 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. 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. If you haven't heard of it, then I will attach . 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. For example, when I first shot my trebuchet I was using a 2.26kg payload and a 22.6kg counterweight. Which brings us to the next point, the overall effectiveness of trebuchets. You can fix this by pressing 'F12' on your keyboard, Selecting 'Document Mode' and choosing 'standards' (or the latest version As an Amazon Associate I earn from qualifying purchases. Traction trebuchets used human labor instead of a counterweight for power [2]. A counterweight trebuchet is powered by a very heavy counterweight, acting on a lever arm. How does the mass and height of the counterweight affect the trebuchet system? The results from this were lackluster. The trebuchet is a large siege weapon that you might recognize from movies set in the Middle Ages or fantasy worlds. Will you need help from an adult to use tools like a power drill or saw? Here is an oversimplified diagram of an armed trebuchet. [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 frame supports all the other parts, and . The force that the catapult needed to launch the projectile came from the manipulation of twisted ropes [3]. guessed the distance. When the counterweight is raised up, it has lots of gravitational potential energy. 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? A trebuchet is a machine where making a change in any one area has an effect on the final result: the fling. These cookies track visitors across websites and collect information to provide customized ads. This aspect of warfare has made tremendous advancements throughout history, with current artillery weapons having the capability of sending projectiles past the horizon and landing within a few feet of their intended targets. Thus, although it was a rather simple machine, the handling required quite some training and coordination. In this blog post, we demonstrated that the Multibody Dynamics Module can be used to build a simple model of a counterweight trebuchet. 6 What are the advantages of a floating arm trebuchet? From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). All rights reserved. The cookies is used to store the user consent for the cookies in the category "Necessary". This cookie is set by GDPR Cookie Consent plugin. The catapult consisted of a solid base with a pivoting arm that would be pulled down and locked into place [1]. Enjoy! To fix How much time do you have to build your trebuchet? Military History Visualized Offical Homepage for the YouTube Channel. A 1:1 sling length to throwing arm ratio builds up the best amount of speed for the projectile. 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. 2). Can you make a trip to the hardware store and build your trebuchet with wood, nuts, and bolts? 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]. Lets begin with the traction trebuchet, which is an older and simpler design. You can vary the weight on the back easily by putting more or fewer rocks inside. 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. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 119) In movies and computer games Trebuchets are often shown as weapons that can destroy city walls and towers easily. When assembled it has an internal capacity of 2600ccs. the side of the tape the projectile landed, we just looked at the meter tape and remember to print the side part twice. 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) This created an increase in falling distance and centrifugal force, both of which contributed to greater power. . 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. PLEASE NOTE: Posts and pages contain amazon affiliate links. (2020, June 23). How heavy should the counterweight and the payload be? It is assumed that the usage of heavy missile throwers was far greater in siege warfare in the Middle East than in Western Europe. The counterweight is cast concrete, 8 inches wide, 15 inch radius from the pivot hole to the curve of the concrete, 108 pounds total. . This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. I made a "trigger" for the catapult out of two big shackles and a rod . One of the final improvements to reach the trebuchet was the propped counterweight [3]. From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123). [11] Ripcords Trebuchet Stuff. 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. The range of a trebuchet has always been important. This consent may be withdrawn. He forced the Scots to remain inside the castle and restarted his siege. Next, grab the handles and pivot to the angle you want it to fire at, then press the lever to release the brutal weapon. many timing errors. too much ballast can result in wasted energy and machine wear. The most efficient way for any counterweight to respond to the force of gravity is by falling in . Mc=30, Mp=0.5, Sa= -46, and Lc=0.321 or 0.5. 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. The trebuchet is the hallmark of medieval siege warfare and is synonymous. At one end of the beam, a sling is attached to hold the projectile. The main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. The complete trebuchet mechanical system is truly a dynamic one. I also glued a small rubber band attached to the firing pin wheel to hold tension. 24 dimes should be placed in the counterweight. Please note: This post contains amazon affiliate links. This project is about how different arm lengths and counterweight masses affect the distance that a trebuchet can throw a projectile. with European battles from England to the balkans. We use technologies like cookies to store and/or access device information. While this is happening, the wheel is moved backwards by the torque acting on the arm from the counterweight. The addition of a fixed counterweight was a major advancement in trebuchet technology. Enjoy! A powerful catapult had the capability to launch a 27-kilogram stone, but had little effect on walls or fortified buildings located over 160 meters away [3]. Here, we build a computational model of a basic trebuchet with the Multibody Dynamics Module and version 5.3 of the COMSOL Multiphysics software. Sling The sling is attached to the long end of the swing arm lever and holds the projectile that is to be thrown. 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. Our model uses the following assumptions and physical dimensions: A schematic of the counterweight trebuchet model. The counterweight is usually very heavy and provides the mechanical force to fire. Once the arm was in place, the projectile would be loaded into a cup at the end of the arm. It does not store any personal data. The counter-weight is usually much heavier than the projectile, typically by a ratio of 10 to 1 or more. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. Machines Power Source.
