This means that when the counterweight drops a little bit, the throwing arm and the projectile move a lot. Two of the major predecessors of the trebuchet were the ballista (Fig. Kaffa was a port city, so the disease soon spread across the Mediterranean and into European ports [3]. 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 most efficient way for any counterweight to respond to the force of gravity is by falling in . Lets see if this holds true for the trebuchet model. To do better, you'll want a sling. between leverage and speed of the arm to achieve the highest velocity. Repeat steps 4 7 to get two more trials on this arm ratio setting, 9. Create an account to follow your favorite communities and start taking part in conversations. 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. 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.

(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. The Chinese invented the trebuchet in 300BC, the French were . 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. 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. The counterweight should be 75 to 100 times the weight of the projectile. Toystub Trebuchet Kit Puzzle 3D Wood Puzzle Wooden Models for Teen. The trebuchet is a large siege weapon that you might recognize from movies set in the Middle Ages or fantasy worlds. 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. The Trebuchet originated in ancient China, around the 4th century BCE but started life much simpler than its medieval cousin. weights from Dick's Sports for $6.99 a piece. The counterweight is cast concrete, 8 inches wide, 15 inch radius from the pivot hole to the curve of the concrete, 108 pounds total. and still have enough energy to throw the projectile at a high velocity. [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. It is assumed that the usage of heavy missile throwers was far greater in siege warfare in the Middle East than in Western Europe. France, John: Western Warfare in the Age of the Crusades 1000-1300, Contamine, Philippe: War in the Middle Ages, Ohler, Nobert: Krieg & Frieden im Mittelalter, McCotter, Stephen: Byzantines, Avars and the Introduction of the Trebuchet. War Wolf proved its worth, and the rest is, as they say, history. 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 pivoting arm would then stop and the projectile would be flung forward. The sling is attached to the end of the long arm of the lever. https://youtu.be/5RZazivVX7k You also have the option to opt-out of these cookies. One is the frame, one is the swing arm, and one is the set of moving parts. It has many of the advantages of a floating arm trebuchet, but with fewer parts, less friction, and a unique projectile launch path. 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. 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. Where should the pivot point be on the beam? 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 FAKA is very efficient for its frame height and arm length as well. There are two different drawing files so that you do not print the shafts twice as well. Record the distance and time on a piece of paper, 8. There are other accounts for other sieges giving a value of about 250 kg (560 lbs). Now, lets examine what happens if we modify the length of the sling by 10% using a parametric sweep. L2 is the distance between the pivot and the sling's attachment point (m). The whipper trebuchet is a modern take on trebuchets, geared toward throwing lighter objects long distance. This cookie is set by GDPR Cookie Consent plugin. Enjoy! I made a "trigger" for the catapult out of two big shackles and a rod . The ratio of the mass of the counterweight to the mass of the payload, expressed as CW:P. A typical MR is 100:1. How long should the arm of a trebuchet be? 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? I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. With the sling in place, the crew just has to change the angle of the sling and the projectile will be aimed at its new target. Actual hand-to-hand combat was quite rare and usually only occurred during midnight counterattacks by the besieged or when the walls of the city were finally breached.

In either case, can you make your analysis more realistic by accounting for things like friction and air resistance? To fix What size planking do I need to make a trebuchet? Anyone who has played Age of Empires (this includes me, yes), will know exactly what a trebuchet is, and what it does. The counter-weight is usually much heavier than the projectile, typically by a ratio of 10 to 1 or more. Its currently set up for a 100:1 counterweight to projectile mass ratio, with 200lbs of counterweight. 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) This toy is a trebuchet, ancient artifact to launch heavy weights against fortifications, with adaptations for simplicity and easy to assemble. It . VirtualTrebuchet is a web based trebuchet simulator that will allow you to quickly evaluate different trebuchet configurations. From what we know it seems that counter-weight trebuchets were used with heavier missiles. Edit Rate (0) Tags Discuss History Files . As the counterweight trebuchet became more popular, engineers thickened castle walls to withstand heavier bombardment. 4.4 4.4 out of 5 stars (13) $32.99 $ 32. Some knowledge of physics will be helpful when doing this project. The projectile is inside a pouch hanging on a sling attached to the long end of a balancing beam. So, if you are in the business of designing trebuchets for medieval kings, you should pay attention to this design parameter. It is sometimes called a counterweight trebuchet or counterpoise trebuchet, to distinguish it from an earlier weapon called the traction trebuchet, which employed pulling men working the mechanism. https://youtu.be/5yMxEXfg85k Credit to Ben Goodwin for helping create this Trebuchet. Ancient Weapon Inspires Student.. Good luck. The poor prospects of surviving an assault from War Wolf prompted the Scottish garrison inside the castle to offer their surrender. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. The ballista eventually gave way to the catapult [3]. 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). If you haven't heard of it, then I will attach . In other words, as long as the release angle is roughly correct, the trebuchet will function as intended. [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. This happened (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 at 5:1, there was not enough power to lift the arm and the projectile 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]. 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. drill the holes for the smaller axle in the first place. The main advantages of the counterweight trebuchet were its ability to fire larger stones and require less manpower during operations. fit. Trebuchet with variable arm ratios, 2. 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. 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]. This cookie is set by GDPR Cookie Consent plugin. What tools and safety equipment do you have access to?

Reproduction of material from this website without written permission is strictly prohibited. An Introduction to Gear Modeling in COMSOL Multiphysics, The Motions and Mechanics of a Truck-Mounted Crane, Multiscale Modeling in High-Frequency Electromagnetics, All of the components are assumed rigid (including the sling), All hinged joints are assumed frictionless, The projectile is prevented from falling through the ground using a penalty stiffness, The counterweight hangs from a beam of length, The swinging arm is 6 meters in total length with. Figure 2 raises several questions about designing a trebuchet. A trebuchet is a long-range weapon that uses a swinging arm to send a projectile toward a target. Set out a meter tape starting from the front of the base and lay on The arm then jerks forward and releases the projectile from the sling. I assume if one includes maintenance into handling that the counterweight trebuchet was harder to handle. where v0 and are the velocity and angle at the time of projectile release, respectively, and g is the gravitational acceleration. 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. It is assumed that it is a Chinese invention and made its way to Europe via the Arab world around the 9th century. Your email address will not be published. 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. These cookies ensure basic functionalities and security features of the website, anonymously. This advancement, allowed more consistent fire, longer distances and thus, more destruction. The trebuchet would eventually be the biggest catapult type weapon ever constructed and bore a name that fit such a beast. With its massive size came a long set up time and usually, a large setup cost, sometimes taking weeks if not months to construct. Science Buddies Staff. The power delivered to a wall from a device like this could be incredibly devastating. All of the parts required to assemble one Trebuchet counterweight. When printing this document, you may NOT modify it in any way. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet, I rebuilt this Trebuchet design in Rhino, made it easier to 3d print. We tried this, 2 thralls is 100 weight, and is Max for the counterweight. - History behind the trebuchet, http://www.ripcord.ws/theory.html Press J to jump to the feed. Defenders used trebuchets against siege towers and the enemy artillery, thus providing what we would call counter-battery fire nowadays. 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. 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. For example, when I first shot my trebuchet I was using a 2.26kg payload and a 22.6kg counterweight. Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. in measurements that we had was in the timing. m2 is the mass of the payload (kg). 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. Bernhard Kast ist Teilnehmer des Partnerprogramms von Amazon Europe S..r.l. 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. The further between . 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). They stood as tall as 60 feet (18m) and could fling 80 pound (36kg) objects up to 980 . They work great over a huge range of mass ratios. be 3:1 and not 5:1. 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 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 . Powered by STLFinder search engine. 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. Artillery has been the centerpiece of many armies over the centuries because of the massive amounts of destruction, fear, and uncertainty it has caused in enemy camps. One of these more modern designs is the . 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. the side of the tape the projectile landed, we just looked at the meter tape and Figure 2: Trebuchet near Urquhart Castle on the shores of Loch Ness, Scotland. Some medieval trebuchets had beams of up to 10 meters and could throw stones of 100 kg as far as 300 meters [1]. He forced the Scots to remain inside the castle and restarted his siege. 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. Here is an oversimplified diagram of an armed trebuchet. Press question mark to learn the rest of the keyboard shortcuts. 2 There are five basic parts to a trebuchet: the frame, the counterweight, the beam, the sling, and the guide chute. Now, since we covered that part, lets get started. Yet, Hill notes that without the addition of a long sling, there was no possible combination that would have made it feasible weapon. An easier way to answer this is 'what didn't they throw'. Do you have a large outdoor area to test a big one? Read the documentation or contact us. Ideally a ratio of around 100/1 ballast to projectile weight should be used, this results in . These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. What experience do you need to become a teacher? 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. Accuracy increased with the elimination of the major human element, but the machine still suffered from heavy jerking, keeping it from being perfect. We do this to improve browsing experience and to show personalized ads. General advice is that the optimal ratio is 133:1. Thus, sometimes stones were transported a long way: This allows the longer projectile arm to move 4 times as far for each . Figure 1, below, shows a modern reconstruction of a trebuchet. [4] Trebuchet.com. 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]. The complete trebuchet mechanical system is truly a dynamic one. Basic Circuits Kit: Conductors and Insulators.

Please note: This post contains amazon affiliate links. too much ballast can result in wasted energy and machine wear. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. A counterweight trebuchet is powered by a very heavy counterweight, acting on a lever arm. To further analyse this phenomenon I have created another graph that keeps a constant counterweight mass and but changes the ratio. 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. Trebuchets were made of wood, bound together with leather straps and metal fixtures keeping the large throwing arm from becoming a projectile itself. For a small trebuchet, you may want to make them 1 foot (30 cm) long; for a larger trebuchet, they can be longer. I designed the basket for 4x1 oz car wheel weights. 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. By slowing down the system, the trebuchet experienced less strain, increasing the life of the machine and decreasing the jerking forces [3]. . l trebuchet counterweight to projectile weight ratio 3d models . Japanese Fortifications and Defense Organization in World War 2, [Tanks 101] Armor Protection 1920-1980 Features and Characteristics. (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) holes for our first axle and had to change the axle when the first one that we A contemporary image of a trebuchet being loaded SOURCE: medievalists.net. 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. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet. This weapon is built on the idea of converting potential energy into kinetic energy to hurl a projectile over a large distance. 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. There is more than one way to tackle the problem. stones up to 275 meters, obliterating walls in their path[7]. Lets begin with the traction trebuchet, which is an older and simpler design. While this is happening, the wheel is moved backwards by the torque acting on the arm from the counterweight. How heavy should the counterweight and the payload be? First, tape the AA battery to one end of a popsicle stick. General wisdom has a 5:1 ratio being the norm for a standard trebuchet, although 4:1 is sometimes used. 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. "Effect of Trebuchet Arm Length or Counterweight Mass on Projectile Distance.". A trebuchet has a lever arm with a large, heavy counterweight on one end and a smaller projectile on the other end. 2 How long should the arm of a trebuchet be? 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.
