floating arm trebuchet efficiency

The Science Project Experiments Catapult Kit. the Parthenon. [45] In 1173, the Republic of Pisa tried to capture an island castle with traction trebuchet on galleys. The traction trebuchet is simpler in design, has a faster rate of fire, increased accuracy, and comparable range and power. For example, if the shorter side of the arm (the counterweight side) is half a meter long, than the longer side of the arm would be 2 meters long. Youll need all the hex nuts and all but 10 of the washers. "It'sThe Hurl itself that matters! [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. Here are my troubleshooting tips that I discovered while tinkering and developing this project plan: The axles for the glide wheels bumps into the drop channel beams. Teach your kids something about safety, posture, focus and How do you make a perfect trebuchet? The origin of the word "trebuchet" is uncertain. Not much is heard of them afterwards. [93] The Mamluks entered the city by sapping the northeast corner of the outer wall. you can. then math, engineering and economics. . Therefore, use only woodcraft that is perfectly straight and well-formed. Will be using this as a rough template for the real thing. What did I do wrong? Traction trebuchets were to be used for hitting people in undefended areas. We are three guys from Sweden who made a Floating Arm Trebuchet as a school project. A loop at the end of the string allows the projectile to attach to the paperclip. So while counterweight trebuchets require significantly fewer men to operate than traction trebuchets, they require significantly more time to reload. Step 2: Mark frame. In the simplest setup, there is nothing designed to absorb energy, and it can not swing back and forth like most trebuchets until it stops. It must hold the boogies or trucks tight against the stop. This is where the projectile will be attached. Click here to toggle editing of individual sections of the page (if possible). The bombardment lasted for hours, but the operators were inaccurate and most of the shots missed their target. I purchased a set of plans from here, for a whopping $7. [52] In China the traction trebuchet was the primary siege engine until the counterweight trebuchet was introduced during the Mongol conquest of the Song dynasty in the 13th century. ASU Library acknowledges the sovereignty of these nations and seeks to foster an environment of success and possibility for Native American students and patrons. studying medicine with plans to become a ridiculously high paid sports According to Matthew of Edessa, this machine weighed 3,400 kg and caused a number of casualties to the city's defenders. Read the documentation or contact us. Dense stone, or even metal, specially worked to be round and smooth, gives the best range and predictability. Here are some stats, note that these apply to the original #2 treb. Create the trigger by tying one 30" (76 cm) piece of string to two 2" (5 cm) pieces of bamboo skewer. The arm should smoothly swing forward as the counterweight falls. The range given for projectiles are 300, 180, and 120 feet. [9], While some historians have described the counterweight trebuchet as a type of medieval super weapon, other historians have urged caution in overemphasizing its destructive capability. Below is. A FAKA is a very high end trebuchet form the efficiency perspective. At the same time, the counterweightes are restricted along the vertical axis. It was a common powerful siege engine until the advent of gunpowder.The design of a trebuchet allows it to launch projectiles of greater weights and further distances than that of a traditional catapult. Categories for minibike_patrol with head word unit: special:unit, Category Nuances matching unit: legislative, grammatical, individual, social, orthographic, natural . According to a stele in Barkul celebrating Tang Taizong's conquest of what is now Ejin Banner, the engineer Jiang Xingben made great advancements on trebuchets that were unknown in ancient times. General Wikidot.com documentation and help section. Of this, the Hongwu Emperor stated in 1388: "The old type of trebuchet was really more convenient. Click here to see our complete line of models and kits. Find out what you can do. 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. The first one built was a Floating Arm Trebuchet, made by Ron Toms. 1 (1995) Introduction: Traction trebuchets were medieval rotating-beam siege engines; they were powered by a human team pulling ropes and hurled stone projectiles from a sling. [15], A trebuchet consists primarily of a long beam attached by an axle suspended high above the ground by a stout frame and base, such that the beam can rotate vertically through a wide arc (typically over 180). It's good for you. [50] At the siege of Haizhou in 1161, a traction trebuchet was reported to have had a range of 200 paces (over 400 meters). It was determined that the optimal arm length ratio was approximately 1:2, where the short arm is 1.7 feet and the long arm is 3.3 feet. What better way to develop an interest in physics than to play A floating arm Trebuchet allows a straight drop of the counterweight which results in more efficiency. How to Simulate a Trebuchet Part 3: The Floating-Arm Trebuchet. This increases he overall efficiency of the trebuchet. While the trebuchet is bieng launched, time the throw from when the projectile leaves the sling to when it hits the ground. "It'sThe Hurl itself that matters! The washers and nuts will be assembled onto the bolt in the order shown. This variation features a drop channel, which allows the counterweight to fall straight down rather than swing with the arm. The floating arm trebuchet is a modern take on an ancient war machine. Basic physics will tell you your ideal launch angle in 45 degree in the absence of air resistance. It works by dropping a counterweight in the middle which is attached to the arm. [58][59] However cases for the existence of both European and Muslim counterweight trebuchets prior to 1187 have been made. [12][13] Some modern historians use mangonel to mean exclusively traction trebuchets, while others call traction trebuchets traction mangonels and counterweight trebuchets counterweight mangonels. [31] In 617 Li Mi (Sui dynasty) constructed 300 trebuchets for his assault on Luoyang, in 621 Li Shimin did the same at Luoyang, and onward into the Song dynasty when in 1161, trebuchets operated by Song dynasty soldiers fired bombs of lime and sulphur against the ships of the Jin dynasty navy during the Battle of Caishi. The mines. Despite its greater range, counterweight trebuchets had to be constructed close to the site of the siege unlike traction trebuchets, which were smaller, lighter, cheaper, and easier to take apart and put back together again where necessary. Ropes of rice straw four inches thick and thirty-four feet long were joined together twenty at a time, draped on to the buildings from top to bottom, and covered with [wet] clay. or turning into a video game zombie! Thanks for sharing! My floating arm trebuchet, built following a slightly modified version of Ron Tom's Plans.Still calibrating, but the range is in excess of 225 feet, my first. General Wikidot.com documentation and help section. Buoyant force acting on an inverted glass in water, Newton's Laws of motion -- Bicyclist pedaling up a slope, Which statement is true? The next step would be for it to be foldable/portable.Nice job ! Cut off any excess dowel to prevent it from getting caught on the drop channel beams. Check out how this page has evolved in the past. 5 years ago It was also mentioned in the Taktika of general Nikephoros Ouranos (c. 1000), and listed in De obsidione toleranda (author anonymous) as a form of artillery. 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. [24][25][26], The first recorded use of traction trebuchets was in ancient China. The FAKA is a trebuchet design invented in late 2006 by Craig Macomber. 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. A large trebuchet was tested in late 2017 in Belfast as part of the set for the television series Game of Thrones.[130]. David Nicolle argues that these events could have only been possible with the use of counterweight trebuchets. 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. The glide rails do not cross into the drop channel. Hello, Sign in. Best Male Enhancement Pills Sold In Stores vigorous male enhancement pills reviews, male enhancement penis injections Male Enhancement Exercises Gnc Male Enhancement. 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. Watch headings for an "edit" link when available. However no other details on the machine are given. He seizes the opportunity and tries to grab at the man's arm, to wrest the sword from his grip but hell he is strong, the templar shoves him against the cobblestone, jagged rock pressing into his back and the cold steel edge of his foe's armor pressing into his chest. This is a more efficient way to transfer potential energy into kinetic energy at a small scale. The Sack of Amorium in 838 saw the use of traction trebuchets to drive away defenders and destroy wooden defenses. A sling is attached to one end of the beam to hold the projectile. This is a more efficient way to transfer potential energy into kinetic energy at a small scale. [103] Trebuchets could cause mass casualties due to the destruction of structures. They were used as ship mounted weapons by 573 for attacking enemy fortifications. the walls and gates of Babylon . Find out what you can do. In general, VirtualTrebuchet will over predict the performance of a trebuchet by some amount because it ignores things like friction. The type described by al-Tarsusi was a hanging counterweight. See pages that link to and include this page. Their defining feature is free movement of an axle on the throwing arm, and a linear drop channel for the counterweight. Jump to page: Lordbob75. The later, and often larger and more powerful, counterweight trebuchet, also known as the counterpoise trebuchet, uses a counterweight to swing the arm. 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. Change the name (also URL address, possibly the category) of the page. In response, the Seljuks constructed another one requiring 400 men to pull and threw stones weighing 20 kg. 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). Prior to 1268, the counterweight trebuchet may have been used in 1232 by the Jurchen Jin commander Qiang Shen. Basically, it gets a lot of energy for it's size and weight, and uses it very well, but there are many challenges. Experiment with a variety of items to find which one will go the farthest. If it does not, the arm will slam into one then the other before it is released. The floating-arm type is. This movement then sends the arm forward launching the projectile from the sling. Floating Arm Trebuchet Page 1 of 3 1 2 3 Last. Unless otherwise stated, the content of this page is licensed under. [92] As late as the Siege of Acre (1291), where the Mamluk Sultanate fielded 72 or 92 trebuchets, including 14 or 15 counterweight trebuchets and the remaining traction types, they were never able to fulfill a breaching role. With. [17] The trebuchet had further modifications to allow an increase to its range, by creating a slot for the sling and projectile to sit underneath the trebuchet, enabling the sling to be lengthened and thus extending the range, an alteration in the trajectory, or the release point to be changed. In reality it will be in the low 30's somewhere. 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. Then, the floating arm trebuchet's arm length ratio and sling length were then optimized. View/set parent page (used for creating breadcrumbs and structured layout). Step 1: Cut lumber. These being fixed, hanging, and hinged counterweights. Trebuchets use a long arm to throw projectiles farther than traditional. [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. [49], Some exceptionally large and powerful traction trebuchets have been described during the 11th century or later. Question The 12th-century Byzantine historian Niketas Choniates may have been referring to a counterweight trebuchet when he described one equipped with a windlass, which is only useful to counterweight machines, at the siege of Zevgminon in 1165. Next thing you know, he'll be Runner Up in the Make it Move Contest 2016. [65][62], Chevedden argues that counterweight trebuchets appeared prior to 1187 in Europe based on what might have been counterweight trebuchets in earlier sources. Hinged counterweights are attached to the arm by a swinging joint. This version won the distance competition against 7 other teams. Then, the floating arm trebuchet's arm length ratio and sling length were then optimized. Looks like a lot of fun ! Men [suddenly] pull [ropes attached to the other] end, and so shoot it forth. The main reason for doing this is to permit the counterweight to move . doctor with a keen knack for investing, all because someone bought him The Norwegian text of 1240, Speculum regale, explicitly states this division of functions. [96] The Templar of Tyre described the faster firing traction trebuchets as more dangerous to the defenders than the counterweight ones. 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 leftover energy goes into battering the axle trucks into the stops, and the hanger into the upper arm stop. Model This results in the counterweight's residual swing being minimized, indicating a more efficient energy transfer. Proven technical team lead and project manager. [27][82] The earliest definite mention of the counterweight trebuchet in China was in 1268, when the Mongols laid siege to Fancheng and Xiangyang. The axle of these trebuchets is wheeled and is allowed to roll along a rail or track. Operation Trebuchet: Efficiency of the Floating Arm Tyler Thibodeau, Drew Prosser, Kevin Chan, and Jack Stevenson 31 May 2011 Governor's School for Science and Technology Author: nguyenque Post on 13-Mar-2018 We launched pumpkins and bowling balls around 10-15 lbs at distances of 300+ feet. This design appeared in the late twentieth century. At the end of the arm there is a sling which holds the stone or stones, of weight and number depending on the stoutness of the arm. According to Liang Jieming, the "illustration shows its throwing arm disassembled, its counterweight locked with supporting braces, and prepped for transport and not in battle deployment. Some fixed counterweights also had a hinged component. A Floating Arm Trebuchet or F.A.T. . The floating arm trebuchet uses a counterweight the vertically falls down a shaft created by two pieces of wood. [138] A more radical design; Jonathan, Orion, and Emmerson Stapleton's "walking arm",[139] described as "a stick falling over with a huge counterweight on top of the stick"[140] debuted in 2016[141] and in 2018 won both the Grand Champion Best Design and Middleweight Open Division of the 10th annual Vermont Pumpkin Chuckin Festival. Learn a new skill. [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. 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. 5. By the 1230s the counterweight trebuchet was a common item in siege warfare. If you want to discuss contents of this page - this is the easiest way to do it. What I do not understand is: 1) How can I find the energy with which the projectile is released? In southern France during the Albigensian Crusade, sieges were a last resort and negotiations for surrender were common. [72], The earliest solid reference to a "trebuchet" in European sources dates to the siege of Castelnuovo Bocca d'Adda in 1199. Although less accurate, traction trebuchets might be expected to achieve the same result, albeit with more shots, in a similar amount of time. Notify administrators if there is objectionable content in this page. The floating arm trebuchet uses a counterweight the vertically falls down a shaft created by two pieces of wood. Next, press the "Simulate" button located under the inputs. Michael the Syrian noted that at the siege of Balis in 823 it was the defenders that suffered from bombardment rather than the fortifications. How to calculate the Resultant force due to a Lever arm? Floating Arm Trebuchet, the most effecient catapult! To fix this problem, we added foam to the bottom of the vertical weight track. All you need is a small and dense object with a string tied to it. are complete with diagrams, photos, tuning tips, equations for calculating the machine's efficiency and more! [43] The Franks and Saxons adopted the weapon in the 8th century. the Lighthouse at Alexandria . [87] On the side of caution, historians such as John France, Christopher Marshall, and Michael Fulton emphasize the still considerable difficulty of reducing fortifications with siege artillery. My FAKA has misfired once, and it lead to the wheels smashing into the front stop and derailing the arm. [99] The superiority of the counterweight trebuchet was not clear cut. If you want to discuss contents of this page - this is the easiest way to do it. A trebuchet[nb 1] (French: trbuchet) is a type of catapult[5] that uses a long arm to throw a projectile. This is termed the "range efficiency", R . During the film, it hurls an incendiary projectile at Stirling Castle. The Floating Everything Trebuchet (FET) - a poor man's FAT, without the vertical guides. Form the base using two whole paint stirrers and the two 6" (cm) pieces. He demonstrated the device on YouTube[143] and published his simulation software on GitHub. on Step 3. on Introduction. This is unlike the violent sudden stop inherent in the action of other catapult designs such as the onager, which must absorb most of the launching energy into their own frame, and must be heavily built and reinforced as a result. Favorited for the next rainy sunday.. This increases he overall efficiency of the trebuchet. It was a common powerful siege engine until the advent of gunpowder. This is the floating arm trebuchet with a sling. The attempt was reportedly unsuccessful: the first projectile landed on the trebuchet itself, destroying it. [10] Other terms, such as machina maior/magna, might have also referred to counterweight trebuchets. Something does not work as expected? [145] The trebuchet was used to project explosives at government troops. [6] They may have been used in Germany from around 1205. Floating Arm Trebuchet - Competition Version The new, stronger F.A.T. [19], A trebuchet projectile can be almost anything, even debris, rotting carcasses, or incendiaries, but is typically a large stone. There are two main types of trebuchet. So, one more time, get some toys and go outside and play! He brushed some of the snow away and it was suddenly blatantly obvious. It recreates the true story that it took some three months to build and Edward would not let his enemy surrender until he could use it. See this page for for images: FAT Trebuchet Model. Share it with us! On this Wikipedia the language links are at the top of the page across from the article title. Both the traction and counterweight trebuchets have been called mangonel at one point or another. One of the most simplest designs but what it has in simplicity it lacks in efficiency. Trebuchets were still used both at the siege of Burgos (14751476) and siege of Rhodes (1480). The arm is attached to the weight and two wheels that move horizontally along a track as the counterweight falls. [36], The catapult, the account of which has been translated from the Greek several times, was quadrangular, with a wide base but narrowing towards the top, using large iron rollers to which were fixed timber beams "similar to the beams of big houses", having at the back a sling, and at the front thick cables, enabling the arm to be raised and lowered, and which threw "enormous blocks into the air with a terrifying noise". [103][105], Rather than replace traction trebuchets, counterweight trebuchets supplemented them in a different role. 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. 1 year ago, Question [102] The counterweight-trebuchet could also be used for cover fire and as an anti-personnel weapon. [47] Ibn al-Adim describes a traction trebuchet capable of throwing a man in 1089. The rollers in the arm can be positioned into different holes, thus altering the position of the fulcrum. Make someone happy. (Velocity and Acceleration of a Tennis Ball). VirtualTrebuchet is a web based trebuchet simulator that will allow you to quickly evaluate different trebuchet configurations. What's the material? Posts : 6,885. Their slower shooting rate and greater mass made them more difficult to reposition, or even yaw, leaving few incentives to employ a small counterweight engine rather than a comparable traction type. 4. | Learn more about Joshua Kukulsky's work experience, education, connections . Center and hot glue the ends of the long pieces to the shorter cross pieces. As mentioned, the angle of the paperclip is a key variable, as well as the type of projectile, and the length of string that its attached to. "[29] Traction trebuchets went into decline during the Han dynasty due to long periods of peace but became a common siege weapon again during the Three Kingdoms period. I would suggest at floating arm Trebuchet.

The design is reportedly quite efficient, similar to a floating arm trebuchet, with a very . Then neither the incendiary arrows, nor bombs [huo pao] from trebuchets, nor even stones of a hundred jun caused any damage to the towers and houses. Codagnellus did not specify a specific type of engine with the term and even implied that they were "fairly light in subsequent references". Notify administrators if there is objectionable content in this page. The counterweight is split into two halves to avoid hitting the center frame. They were commonly called stone-throwing machines, thunder carriages, and stone carriages in the following centuries. Super awesome! 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. 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. Writing in 1280, Giles of Rome claimed that hinged counterweight trebuchets had a greater range than fixed counterweight types. When the trebuchet is operated, the force causes rotational acceleration of the beam around the axle (the fulcrum of the lever). Another trebuchet I designed and built for a school project. Although rarely used as a weapon today, trebuchets maintain the interest of professional and hobbyist engineers. Step 4: Assemble trebuchet sides. The Pyramids of Egypt. I just subscribed because I like that you have so many mechanical contraption based Instructables. Paint stirrer: ruler, wood shim, craft sticks, or another flat, rigid strip of wood. Discard warped or defective pieces before building. Carried westward by the Avars, the technology was adopted by the Byzantines in the late 6th century AD and by their neighbors in the following centuries.
