[58][59] However cases for the existence of both European and Muslim counterweight trebuchets prior to 1187 have been made. [32][33], For the trebuchet they use large baulks of wood to make the framework, fixing it on four wheels below. So while counterweight trebuchets require significantly fewer men to operate than traction trebuchets, they require significantly more time to reload. Minimum age: 14Availability: out of stock. [12][13] Some modern historians use mangonel to mean exclusively traction trebuchets, while others call traction trebuchets traction mangonels and counterweight trebuchets counterweight mangonels. A sling is attached to one end of the beam to hold the projectile. They work great over a huge range of mass ratios. [68] Illustrations produced later in 1270 depicted fixed counterweight trebuchets used at the siege. A pair of wheels allows the arm to roll along However, you may be able to glue four square chopsticks into a thicker beam. Of course, when properly tuned, there is very little energy left (The FAKA can be tuned for very high efficiency), but before its tuned, or in the event of a misfire things can go quite wrong. [83] Chinese and Muslim engineers operated artillery and siege engines for the Mongol armies. This variation features a drop channel, which allows the counterweight to fall straight down rather than swing with the arm. Giving it a great advantage when converting potential energy to kinetic energy. . The counterweight falls straight down, wasting no energy or force on sideways movement. on Step 3. The combination of FAT and KA does have a cost. All you need is a small and dense object with a string tied to it. These factors multiply the acceleration transmitted to the throwing portion of the beam and its attached sling. Therefore, use only woodcraft that is perfectly straight and well-formed. According to the Song of the Albigensian Crusade, the defenders "ran to the ropes and wound the trebuchets", and to shoot the machine, they "then released their ropes. English Deutsch Franais Espaol Portugus Italiano Romn Nederlands Latina Dansk Svenska Norsk Magyar Bahasa Indonesia Trke Suomi Latvian Lithuanian esk . [102] The counterweight-trebuchet could also be used for cover fire and as an anti-personnel weapon. 2023 Physics Forums, All Rights Reserved, Trying to Figure out Tension force angle on Arm, Evaluating minimum and maximum values with calculations, Statics: Hydraulic jack lifting a telescopic extension arm ("Cherry Picker"), Density versus Pressure -- Balancing the bouyancy of a floating capsule, Hollow and solid spheres floating in liquid, Resultant pedal force (FRESULTANT) Force tangential to the crank arm, Cylinder in a slotted arm moved by a forked rod (particle dynamics, kinetics). Create the trigger by tying one 30" (76 cm) piece of string to two 2" (5 cm) pieces of bamboo skewer. Question Chevedden, Paul E.; et al. The traction trebuchets provided cover fire while the counterweight trebuchets destroyed the city's fortifications. The treb built for this guide is slight different, partly due to design and partly due to the materials that I had to work with, e.g. | Learn more about Joshua Kukulsky's work experience, education, connections . In general, VirtualTrebuchet will over predict the performance of a trebuchet by some amount because it ignores things like friction. Account & Lists Returns & Orders. The mechanical advantage is primarily obtained by having the projectile section of the beam much longer than the opposite section where the force is applied usually four to six times longer.[16]. The counterweight is split into two halves to avoid hitting the center frame. The floating arm trebuchet uses a counterweight the vertically falls down a shaft created by two pieces of wood. Thanks for sharing! [41][42] Like the Chinese, by 653, the Arabs also had ship mounted traction trebuchets. FAKAs have several parts, most of which are similar to other types of trebuchets. It first appeared in China in the 4th century BC. doctor with a keen knack for investing, all because someone bought him On the side of the counterweight engine as a medieval military revolution, historians such as Sydney Toy, Paul Chevedden, and Hugh Kennedy consider its power to have caused significant changes in medieval warfare. I would like to work on the floating arm trebuchet because the design of it is more interesting and The bombardment lasted for hours, but the operators were inaccurate and most of the shots missed their target. Posts : 6,885. you can. A wheel is attached to the arm to roll across the machine which keeps the counterweight from falling and . This awesome. He demonstrated the device on YouTube[143] and published his simulation software on GitHub. [96] The Templar of Tyre described the faster firing traction trebuchets as more dangerous to the defenders than the counterweight ones. [45] In 1173, the Republic of Pisa tried to capture an island castle with traction trebuchet on galleys. "[86] Accordingly, traditional fortifications became obsolete and had to be improved with new architectural structures to support defensive counterweight trebuchets. 3. interact. Glue the split paint stirrer pieces at an angle to support the glide rails and drop channel. Model It's good for you. Straighter counterweight drop; Reduces frame stress; Increased efficiency; Disadvantages. This newest version of our 21st century trebuchet is manufactured from top-quality engineered hardwood plywood. [18] Further increasing their complexity is that either winches or treadwheels, aided by block and tackle, are typically required to raise the more massive counterweights. the walls and gates of Babylon . In a long siege, reload time may not be a critical concern. During an assault on Muntcada by King James I a trebuchet was used to target a tower, destroying the structure and causing the consequential deaths of civilians and livestock. [30] It seems that during the early 7th century, improvements were made on traction trebuchets, although it is not explicitly stated what. Is it possible to make it so you can just attach a weight to the end? the Parthenon. Step 1: Cut lumber. If it does not, the arm will slam into one then the other before it is released. Jump to page: Lordbob75. Step 3: Drill holes for pivot arm. How's that for a reason? Arizona State University's four campuses are located in the Salt River Valley on ancestral territories of Indigenous peoples, including the Akimel Oodham (Pima) and Pee Posh (Maricopa) Indian Communities, whose care and keeping of these lands allows us to be here today. Enter the modified floating arm trebuchet. This is termed the "range efficiency", R . The floating-arm type is. See this page for for images: FAT Trebuchet Model. This machine lets you get your counterweight higher than a traditional trebuchet but keeps the pivot point low enough to keep with the rules of our competition. Usually gravity or springs. Step 7: Attach braces. they're learning it. [47] At the Siege of Kamacha in 766, Byzantine defenders used wooden cover to protect themselves from the enemy artillery while inflicting casualties with their own stone throwers. Floating Arm In this design the counterweight is constrained by a track to fall dead vertical, and the entire throwing arm, running on wheels set in a horizontal track, shifts to accomodate the counterweight. Did you make this project? Bryce Lowe. Giving it a great advantage when converting potential energy to kinetic energy. The Traction Trebuchet: A Reconstruction of an Early Medieval Siege Engine By W. T. S. Tarver Technology and Culture, Vol. Step 5: Drill holes for axles. The traction trebuchet is simpler in design, has a faster rate of fire, increased accuracy, and comparable range and power. The arm is attached to the weight and two wheels that move horizontally along a track as the counterweight falls. Here are some stats, note that these apply to the original #2 treb. [88] Marshall maintains that "the methods of attack and defence remained largely the same through the thirteenth century as they had been during the twelfth. [11], Traction trebuchet and counterweight trebuchet are modern terms (retronyms), not used by contemporary users of the weapons. Price: $195.00 Windows 7 Ultimate x64, Mint 9 New 15 Jan 2010 #1. This is where the projectile will be attached. The 5 degrees of freedom are the x and y coordinates of the projectile, the height of the counterweight, and the sling and arm angles. FAKAs are hard to build, and have have a tendency to go very wrong, and often break things, if the timing is a little off. The floating arm trebuchet is a modern take on an ancient war machine. The term traction trebuchet was created mainly to distinguish this type of weapon from the onager, a torsion powered catapult that is often conflated in contemporary sources with the mangonel, which was used as a generic term for any medieval stone throwing artillery. Invented in the late 1990's, it uses the same physics involved with a normal trebuchet. One of the most simplest designs but what it has in simplicity it lacks in efficiency. The pins should fit in the holes loosely. Share it with us! The main reason for doing this is to permit the counterweight to move . ASU Library welcomes members of the Akimel Oodham and Pee Posh, and all Native nations to the Library. plus of a linear mass drop is that you should be able to make the mechanism pretty low friction and pull off some good efficiency numbers. A large trebuchet based on Edward I's "Warwolf" was constructed for a scene in David Mackenzie's movie Outlaw King (2018)[citation needed] about Robert the Bruce, King of Scots. "It'sThe Hurl itself that matters! Runner Up in the Make it Move Contest 2016. [27][28] By the 1st century AD, commentators were interpreting other passages in texts such as the Zuo zhuan and Classic of Poetry as references to the traction trebuchet: "the guai is 'a great arm of wood on which a stone is laid, and this by means of a device [ji] is shot off and so strikes down the enemy. How do you make a perfect trebuchet? Click here to toggle editing of individual sections of the page (if possible). To begin, enter the parameters of your trebuchet in the input boxes. [44] The Life of Louis the Pious contains the earliest western European reference to mangonels (traction trebuchets) in its account of the siege of Tortosa (808809). Another trebuchet I designed and built for a school project. In southern France during the Albigensian Crusade, sieges were a last resort and negotiations for surrender were common. This version won the distance competition against 7 other teams. A fixed counterweight is an intrinsic part of the swinging arm and its trajectory is circular. What did I do wrong? The axle of these trebuchets is wheeled and is allowed to roll along a rail or track. [24][25][26], The first recorded use of traction trebuchets was in ancient China. A straighter paperclip will result in a quicker release and a higher trajectory. Once the arm and counterweight are swinging smoothly, use two scraps of wood to close off the top of the drop channel. Hinged counterweights are attached to the arm by a swinging joint. [113][114], Most trebuchet use in recent centuries has been for recreational or educational, rather than military purposes. D.J. [137] Instead of using the traditional axle fixed to a frame, these devices are mounted on wheels that roll on a track parallel to the ground, with a counterweight that falls directly downward upon release, allowing for greater efficiency by increasing the proportion of energy transferred to the projectile. Known as the Huihui trebuchet (, where "huihui" is a loose slang referring to any Muslims), or Xiangyang trebuchet () because they were first encountered in that battle. It was a pole with a pin at its upper end that acted as a fulcrum for the arm. Find out what you can do. Move the arm to position 1. As their construction is substantially simpler than modern weapons, trebuchets also serve as the object of engineering challenges. Acknowledgement . . Make someone happy. "-TheHurl, Creative Commons Attribution-ShareAlike 3.0 License. They were probably used by the Mohists as early as 4th century BC; descriptions can be found in the Mojing (compiled in the 4th century BC). He brushed some of the snow away and it was suddenly blatantly obvious. Set out a meter tape starting from the front of the base and lay on ground. The floating arm trebuchet is a modern take on an ancient war machine. The entire argument for the existence of hybrid trebuchets rests on accounts of increasingly more effective siege weapons. This is bad because it adds stress to the frame when it re-contacts the ground, and could (And I think it did) derail the axle.1. The Norwegian text of 1240, Speculum regale, explicitly states this division of functions. It's easy if they have something fun to do while [7] In Arabic the counterweight trebuchet was called manjaniq maghribi or majaniq ifranji. [6] Only in the late 1210s do variations of "trebuchet" in sources, described as increasingly powerful machines or utilizing different components, identify more closely with the counterweight trebuchet. I purchased a set of plans from here, for a whopping $7. Click here to edit contents of this page. The further between them the better they will reduce this twisting. Both Liang and Needham note that the illustrations are poorly drawn and confusing, leading to mislabeling. What I do not understand is: 1) How can I find the energy with which the projectile is released? When attempting to breach enemy walls, it is important to use materials that will not shatter on impact; projectiles were sometimes brought from distant quarries to get the desired properties. How to calculate the Resultant force due to a Lever arm? It combines the efficiency of a Floating Arm Trebuchet (FAT) with the increased potential energy of a King Arthur. Click here to see our complete line of models and kits. "[100] The traction trebuchet continued to serve as an anti-personnel weapon. the wheels:-height to top of arm when at rest 9 inches. It combines the efficiency of a Floating Arm Trebuchet (FAT) with the increased potential energy of a King Arthur. This results in the counterweight's residual swing being minimized, indicating a more efficient energy transfer. Advantages. The first one built was a Floating Arm Trebuchet, made by Ron Toms. And you know where that leads First, physics, motion. Dense stone, or even metal, specially worked to be round and smooth, gives the best range and predictability. [71] Chevedden argues that given the references to new and better trebuchets that by the 112030s, the counterweight trebuchet was being used in a variety of places by different peoples such as the crusader states, the Normans of Sicily and the Seljuks. The trebuchet is 2 meters (6,5 ft) high.Blueprints:http://postimg.org/image/qzydc1109/http://postimg.org/image/8mxs1gqjd/http://postimg.org/image/htg2oqvrt/(Sorry for bad quality) The word trabuchellus appeared alongside manganum and prederia in a document in Vicenza on 6April 1189 (833 years ago)(1189-04-06). December 7th, 2011. Torrent: Great Courses - Science (1.4 TB) Has total of 2749 files and has 0 Seeders and 0 Peers. [8][61] Later during the 13th century, Muslims used manjaniq maghribi (Western trebuchet) and manjaniq ifranji (Frankish trebuchet) to refer to counterweight trebuchets. [100], The hand-trebuchet (Greek: , cheiromanganon) was a staff sling mounted on a pole using a lever mechanism to propel projectiles. These ranges of the full scale models were surprisingly accurate with what was predicted. Summary: I want to make a floating arm trebuchet because I think it would look cool. The floating-arm type is distinct from the ordinary trebuchet in that its arm has no fixed pivot; that is, it "floats" during a launch. 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. The projectile is thrown when the beam is quickly rotated by applying force to the opposite end of the beam. Seriously, get some toys, go outside and play. The Floating arm Trebuchet: The fixed Counterweight Trebuchet: A fixed counterweight with a fixed frame design. The oddity with this trebuchet is that it has no arm ratio as the counterweight sits at the very end of the arm, and the arm itself tends to be shorter. The 51-foot-tall (16m), 55,000-pound (25,000kg) trebuchet flings the standard 810-pound (3.64.5kg) pumpkins,[129] specified for all entries in the WCPC competition. Finally, the mathematical models were compared to full scale models. "[91] In 1220, Al-Mu'azzam Isa laid siege to Atlit with a trabuculus, three petrariae, and four mangonelli but could not penetrate past the outer wall, which was soft but thick. Friction when the counterweight is dropping down to the glide strike can be reduced by using silicone grease or a thin film of plastic on the drop channel. However no other details on the machine are given. Will be using this as a rough template for the real thing. This will be the roller that travels over the glide rails. These being fixed, hanging, and hinged counterweights. 7. Prior to 1268, the counterweight trebuchet may have been used in 1232 by the Jurchen Jin commander Qiang Shen. [67] At the siege of Nicaea in 1097 the Byzantine emperor Alexios I Komnenos reportedly invented new pieces of heavy artillery which deviated from the conventional design and made a deep impression on everyone. Below is. This line of thought suggests that rams were abandoned due to the effectiveness of the counterweight trebuchet, which was capable of reducing "any fortress to rubble. With. I would suggest at floating arm Trebuchet. One modern technological development, especially for the competitive pumpkin-hurling events, is the "floating arms" design. King James I of Aragon employed this as a defensive tactic in many fortified structures and towns which proved effective. The Pyramids of Egypt. [131][132] In the episode "Carnage A Trois" in series 4 of The Grand Tour the presenters uses a trebucet to allegedly sling a Citron C3 Pluriel from the White Cliffs of Dover across the English Channel. Wrap layers of masking tape around the round dowel until the thickness is slightly larger than the center of the washers. We are three guys from Sweden who made a Floating Arm Trebuchet as a school project. Click here to Magnet Download the torrent. You are using an out of date browser. This project requires precision to work consistently. The sling starts rotating with the beam, but rotates farther (typically about 360) and therefore faster, transmitting this increased speed to the projectile. [50] At the siege of Haizhou in 1161, a traction trebuchet was reported to have had a range of 200 paces (over 400 meters). [66] However the source for this was written in the 1180s to 1190s and Niketas may have been placing the engine of his own time anachronistically into the past. It may not display this or other websites correctly. In 2021, an individual named David Eade designed a trebuchet reaching supersonic speed. Set the counterweighted arm into the drop channel. KBladin 82 subscribers Subscribe 459 108K views 12 years ago We are three guys from Sweden who made a Floating Arm Trebuchet as a. Unless otherwise stated, the content of this page is licensed under. There are several subtle but key variables that influence how well the trebuchet performs. https://jaanmarss.planet.ee/juhendid/Mehaanilised_kaugrelvad_keskajal/andmebaas/Russell%20Miners/htt01.html, "Medieval Warfare during the Cathar Crusades", "War in the South: A First Look at Siege Warfare in the Albigensian Crusade, 12091218", "By hook or by crook: Siege warfare in the fourteenth century", "armedieval - le trebuchet et les machines civiles et militaires mdivales", "World Championship Punkin Chunkin Current World Records", "Season 8 Filming: Watch a trebuchet test at Titanic Studios", Experts reveal the science behind 'the world's biggest trebuchet' on You Have Been Warned, Car is launched from trebuchet at Shropshire fundraiser, The Grand Tour: This Is What Happened To The Carnage A Trois Trebuchet, The Grand Tour's "Carnage a Trois" Episode Falls Largely Flat, YouTuber Colin Furze creates trebuchet in Stamford, THIS MASSIVE HOMEMADE TREBUCHET CAN LAUNCH WASHING MACHINES, "World's Simplest and Newest Trebuchet (Walking Arm Trebuchet): 17 Steps (with Pictures)", "Vermont Pumpkin Chuckin' Festival: Results of the 10th annual Vermont Pumpkin Chuckin Festival", "Vermont Pumpkin Chuckin' Festival: The Final Results and Report for the 8th Annual Vermont Pumpkin Chuckin' Festival on Sept. 25th, 2016", "Ukrainian Protesters Built A Giant Catapult To Fight The Riot Police", "English Artillery 1189-1307: The Implications of Terminology", "Experimental Reconstruction of the Medieval Trebuchet", "By Hook or by Crook: Siege Warfare in the Fourteenth Century", "The Traction Trebuchet: A Reconstruction of an Early Medieval Siege Engine", "Trebuchet - A Gravity-Operated Siege Engine: Study in Experimental Archaeology", Secrets of Lost Empires: Medieval Siege (building of and history of trebuchets), https://en.wikipedia.org/w/index.php?title=Trebuchet&oldid=1142306451, Articles with dead external links from June 2022, Articles with permanently dead external links, All articles with bare URLs for citations, Articles with bare URLs for citations from August 2022, Wikipedia pending changes protected pages, Short description is different from Wikidata, Articles with unsourced statements from January 2022, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 1 March 2023, at 17:51. this variation features drop DismissTry Ask an Expert Ask an Expert Sign inRegister Sign inRegister Home Ask an ExpertNew My Library Discovery Institutions University of Georgia Maryville University Harvard University [97] The Song dynasty described countermeasures against counterweight trebuchets that prevented them from damaging towers and houses: "an extraordinary method was invented of neutralising the effects of the enemy's trebuchets. The bar that held the weight bent frequently. Cut off any excess dowel to prevent it from getting caught on the drop channel beams. [63][64] Hanging counterweights hang below the arm and drop vertically. [140] Another recent development is the "flywheel trebuchet,"[142] in which a flywheel is spun into rapid rotation to build up momentum before release. When you make a purchase through these links, I may earn an affiliate commission at zero cost to you. The design forces the counterweight to fall in a semi circular arc rather than a vertical arc making it lose some if its power. The FAKA is a trebuchet design invented in late 2006 by Craig Macomber. A floating arm trebuchet has three points of contact where friction can interfere with efficiency. The length of the sling increases the mechanical advantage, and also changes the trajectory so that, at the time of release from the sling, the projectile is traveling in the desired speed and angle to give it the range to hit the target. They were used as defensive weapons stationed on walls and sometimes hurled hollowed out logs filled with burning charcoal to destroy enemy siege works. The hinged trebuchet achieved efficiencies of 0.8065 for both range and energy efficiency and the "see-saw" with efficiencies of only 0.567 and 0.570, respectively. Published 7 years ago. The boogies, or trucks, which ride the tracks, need to prevent the axle from twisting relative to the frame, If one side gets ahead of the other, it will likely jam, but the counterweight or the arm might also strike the frame. Giving a total length of 2.5 meters. The leftover energy goes into battering the axle trucks into the stops, and the hanger into the upper arm stop. [19], A trebuchet projectile can be almost anything, even debris, rotting carcasses, or incendiaries, but is typically a large stone. We're doing our part, now you need to do yours. [144], In 2013, during the Syrian civil war, rebels were filmed using a trebuchet in the Battle of Aleppo. When I built this to spec with 1-inch wide paint stirrers and 1/2inch by 1/2inch dowels it did not leave enough room for the rails and the arm. Find out what you can do. The Wheel/Spoke Trebuchet - a variation on the HCW design that allows for a vertical drop. Make sure the throwing arm rests between the glide rails before launch as shown in the image above. This is the floating arm trebuchet with a sling. The earliest depiction of a hybrid trebuchet is dated to 1462, when trebuchets had already become obsolete due to cannons.
