trebuchet counterweight ratio

Launches 25 feet. I would recommend bring at least 2-300 . (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 counterweight is cast concrete, 8 inches wide, 15 inch radius from the pivot hole to the curve of the concrete, 108 pounds total. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); The medieval battlefield was dominated by large artillery weapons, and among these the trebuchet was king. Based on historical designs, it stands 18 metres (59 ft) tall and throws missiles typically 36 kg (80 lbs) up to 300 metres (980 ft). Larger trebuchets would have large 'hamster' style wheels on the side of them, allowing men to run inside them to winch down the large arm where the projectile would be added, a pin would then be removed throwing the large arm upwards. Trebuchet. Internet: http://en.wikipedia.org/wiki/Trebuchet, [Oct. 11, 2006]. Do you need to use household materials like cardboard, duct tape, and string? In use for almost 1000 years, the medieval version of the Chinese trebuchet transformed the battlefield thus changing the world forever. Bernhard Kast ist Teilnehmer des Partnerprogramms von Amazon Europe S..r.l. There is more than one way to tackle the problem. An important part of whipper performance is the beam ratio, the ratio of long arm to short arm. it will likely jam, but the counterweight or the arm might also strike the frame. The lead attached to the NOVA-built, fixed-weight trebuchet weighed a hefty six-and-one-half tons. The counterweight should be 75 to 100 times the weight of the projectile. You can fix this by pressing 'F12' on your keyboard, Selecting 'Document Mode' and choosing 'standards' (or the latest version I created a new swing arm, but the one in the MOving parts Olympic Weight Adapter for CEM60 Counterweight Bar. 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 poor prospects of surviving an assault from War Wolf prompted the Scottish garrison inside the castle to offer their surrender. What about moments of inertia, which are not labeled in Figure 3? This happened (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). 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. Another error that could have occurred was the axle 2 How long should the arm of a trebuchet be? 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. A trebuchet is a type of catapult that uses a counterweight to engage the armwhich is attached to a slingand launch projectiles. By providing your email address, you consent to receive emails from COMSOL AB and its affiliates about the COMSOL Blog, and agree that COMSOL may process your information according to its Privacy Policy. 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 main advantages of the traction trebuchet were that it was faster and cheaper to build and needed no specialists, unlike the counterweight trebuchet. Christopher Carrillo was born in Monterey Park, CA. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. By clicking Accept All, you consent to the use of ALL the cookies. Trebuchet Essay. Do you have time to do a fancy design, or do you need to build one quickly? A build it yourself 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]. h is the initial height of the counterweight off the ground. Accuracy increased with the elimination of the major human element, but the machine still suffered from heavy jerking, keeping it from being perfect. I have a basic understanding that the more weight you put in the counterweught item slots, the further the shot will go. 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]. measuring, and the axel connection. 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." Some errors that we might have had in our experiment include, wind, For a very impressive science project, you could also compare the range of the trebuchet you build to predictions based on hand calculations and/or computer simulations you make (above). 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. A trebuchet exists as a medieval rock throwing machine, but quite different to a catapult. 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. One is the frame, one is the swing arm, and one is the set of moving parts. What tools and safety equipment do you have access to? Create an account to follow your favorite communities and start taking part in conversations. and still have enough energy to throw the projectile at a high velocity. 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. 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? In addition to unequal weights, the trebuchet uses leverage. How closely do they match? Since the counterweight weighs in at 1lb, 6oz (on a postal scale), the ideal projectile seems to be a standard glass marble (lighter than I would have guessed, at .2oz). Our design was very stout and held around 720lbs in counterweight, not including the weight bar and arm itself. The beam ratio of the Counterweight Trebuchet was also around 5:1 or 6:1.

[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. The Scrohammer happily hurls these wee glass spheres of doom a surprising distance of 40 feet. The Trebuchet works functional but the connection between each parts seems weak and need to be improved. . This cookie is set by GDPR Cookie Consent plugin. To throw the payload as far as possible, how long should the beam be? The trebuchet was preferred over a catapult due to its greater range capability and greater accuracy. Whatever you decide you want to launch with your trebuchet, your counterweight should be from 100 to 133 times the weight of your projectile. However, you may visit "Cookie Settings" to provide a controlled consent. of your trebuchet be? Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. be 3:1 and not 5:1. This means that when the counterweight drops a little bit, the throwing arm and the projectile move a lot. 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 maximum throwing distance is obtained if the projectile is released at 38. https://youtu.be/5RZazivVX7k 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]! 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. (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) Regardless of wether this specific event took place, bodies or at least body parts were used to ruin the days of besieged peoples, leading sometimes to mass outbreaks of diseases, wiping out entire cities without the attackers ever storming the walls. Hill states about the Counterweight Trebuchet: Simple as it seems, the trebuchet is a complicated dynamical system. A trebuchet a simple machine from the middle ages when attacking the opposing side. 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. because at 5:1, there was not enough power to lift the arm and the projectile Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. Counterweight trebuchet was invented by Muslims, and then the Mongols introduced it into the Chinese battlefield and used it to capture China's Xiangyang, that is, the special unit of the Mongolian campaign. Do you have a large outdoor area to test a big one? 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. - History and details of the trebuchet, - Plans and directions for building a small trebuchet, http://www.io.com/~beckerdo/other/trebuchet.html. 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. I assume if one includes maintenance into handling that the counterweight trebuchet was harder to handle. Youll need to cut 8 pieces: Two long base pieces. The graph displays the range of projectile as the y-axis and the ratio as the x-axis. How much counterweight does a trebuchet need? First, tape the AA battery to one end of a popsicle stick. Defenders used trebuchets against siege towers and the enemy artillery, thus providing what we would call counter-battery fire nowadays. Ideally a ratio of around 100/1 ballast to projectile weight should be used, this results in . (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). 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. A contemporary image of a trebuchet being loaded SOURCE: medievalists.net. General wisdom has a 5:1 ratio being the norm for a standard trebuchet, although 4:1 is sometimes used. It considers several models of varying complexity and finds a maximum range efficiency of 83% for a 100 pound counterweight, 1 pound projectile, a 5 foot long beam pivoted 1 foot from the point of attachment of the counterweight, and a 3.25 foot long . Trebuchet. At one end of the beam, a sling is attached to hold the projectile. Never "dry fire" the trebuchet - always load a projectile to balance the firing mechanism. In movies and computer games Trebuchets are often shown as weapons that can destroy city walls and towers easily. In this blog post, we demonstrated that the Multibody Dynamics Module can be used to build a simple model of a counterweight trebuchet. (2006, Oct. 12) Military Technology., [8] R. Meyer, Column One; How Far Can a Piano Fly?, [10] D. Moe. "Effect of Trebuchet Arm Length or Counterweight Mass on Projectile Distance.". Some knowledge of physics will be helpful when doing this project. 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. A small-scale replica of War Wolf, a counterweight trebuchet that uses a boulder-holding sling at the end of a swinging arm. In terms of operating, it depends to a certain degree on the perspective, which one was, Hill notes the following: 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. The floating arm trebuchet uses a counterweight held on top of a tall drop channel to transfer potential energy into kinetic energy. 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). . Counterweight is filled with spare change. 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. 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]. Yet, one would assume that proper calculations or laborious trial and errors of various variations could produce an effective counterweight-trebuchet. (2020, June 23). (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 280-282) And the more complex counterweight Trebuchet were the force was provided by a counterweight, although it gives a rather simple impression, it was a quite complicated machine once you dive into the dynamics of it.

We tried 100x Ironstone ore (10.00 "weight") and Heavy Armor, but none of it seemed to work better. Now, lets look at the range, there are no proper accounts according to Hill, but he assumes that 275 m (900 ft) should be correct. pushing it forward, or pushing it backwards. 2 stacks of fire arrows are the same. This created an increase in falling distance and centrifugal force, both of which contributed to greater power. Note: A trebuchet utilizes specific measurements to throw a projectile using the power of a falling weight. I chose the most obvious coordinate system, using three angles, but perhaps a Cartesian system is easier. 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 need to build a miniature trebuchet that fits on a tabletop? Yet, Hill notes that without the addition of a long sling, there was no possible combination that would have made it feasible weapon. Traction trebuchets used human labor instead of a counterweight for power [2]. . You also have the option to opt-out of these cookies. http://imgur.com/CntygEE https://en.wikipedia.org/wiki/Trebuchet, SummaryI rebuilt this Trebuchet design in Rhino, made it easier to 3d print. 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. . How long should the arm of a trebuchet be? 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. 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. On the other hand, at the 3:1 ratio there was just the right balance The catapult consisted of a solid base with a pivoting arm that would be pulled down and locked into place [1]. We also use third-party cookies that help us analyze and understand how you use this website. 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. 3). 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! m2 is the mass of the payload (kg). What are various methods available for deploying a Windows application? (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 274 & 280). Adult supervision is required when building and operating a trebuchet. The main beam, counterweight box, sling, projectile, trough, windlass, and framework are all clearly visible with dimensions given for some of the component parts. (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: Here is an oversimplified diagram of an armed trebuchet. 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. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. The animation below shows the motion of the trebuchet as it is fired. The first of these, a "black box" model in which the mechanism for the On a trebuchet, it's much closer to the counterweight. fit. The further between . Catapulting Science Into Fun.. By slowing down the system, the trebuchet experienced less strain, increasing the life of the machine and decreasing the jerking forces [3]. 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 counter-weight arm of the seesaw is usually shorter than the projectile arm by a ratio of 4 to 1 or more. Pictures. 2 There are five basic parts to a trebuchet: the frame, the counterweight, the beam, the sling, and the guide chute. The ratio between the counterweight and the payload is important, and this may dictate the size of your trebuchet. I hope you enjoyed this and would love to hear what you think, please leave me a comment and follow me on Instagram @chrisriley_ for more medieval history! 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! 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. The trebuchet is the hallmark of medieval siege warfare and is synonymous. Thus, the counter-weight trebuchet had to be constructed with a stronger beam, which reduces its effectiveness quite considerably. However, as I said earlier, a 1:4 ratio arm isn't going to throw anything very far on its own. So, if you are in the business of designing trebuchets for medieval kings, you should pay attention to this design parameter. The Chinese invented the trebuchet in 300BC, the French were . Enjoy! Edit Rate (0) Tags Discuss History Files . Machines Power Source. Consequently, trebuchets dominated the battlefield with their ability to fling 300 lb. Continued made broke, the connection between the new axle and the arm was loose and For centuries, the trebuchet was the most powerful war machine in the world. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. 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). [5] Wikipedia. Repeat steps 4 7 to get two more trials on this arm ratio setting, 9. Enjoy! A counterweight trebuchet is powered by a very heavy counterweight, acting on a lever arm. Your arms will float up from your sides, as if lifted by an external force. Whereas the traction trebuchet had the force only applied for a short amount of time. This cookie is set by GDPR Cookie Consent plugin. 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 . What is your budget, and what materials do you have access to? For a small trebuchet, you may want to make them 1 foot (30 cm) long; for a larger trebuchet, they can be longer. 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). It does not store any personal data.

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. For a sling, I use the handle from a plastic grocery bag. 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. Figure 1, below, shows a modern reconstruction of a trebuchet. What is the best ratio for a trebuchet? Your email address will not be published. Can you pick these parameters based on hand calculations or computer simulations (above), or based on design information you found through your own research? 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. 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. The easiest counterweight to attach is a small bucket. Less tunable than HCW trebuchets at high ratios. 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. 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. many timing errors. That's a weight ratio of 1:110. Licensed under CC BY 3.0, via Wikimedia Commons. The pivoting arm would then stop and the projectile would be flung forward. - user21033 Mar 24, 2013 at 16:03 Add a comment 0 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. YAQUMW The Mini Counterweight Trebuchet with Wheel Europe Medieval Siege Chariot Catapult Weapons DIY 3D Wooden Puzzles Mechanical Model Kits for Adults STEM Projects Tabletop Toys Birthday Gift. another potential negative for the trebuchet is its immovability. Science Buddies Staff. 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.
