trebuchet counterweight ratio

What is the best ratio for a trebuchet? as it ends up shaking around on the A trebuchet built for engineering class. The lead attached to the NOVA-built, fixed-weight trebuchet weighed a hefty six-and-one-half tons. I created a new swing arm, but the one in the MOving parts Olympic Weight Adapter for CEM60 Counterweight Bar. What real-world things (like air resistance, or how exactly the payload is released from the sling) were difficult to account for in your calculations or simulations? 4.4 4.4 out of 5 stars (13) $32.99 $ 32. 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. They work great over a huge range of mass ratios. Bernhard Kast ist Teilnehmer des Partnerprogramms von Amazon Europe S..r.l. The ballista eventually gave way to the catapult [3]. A trebuchet is a type of catapult that uses a counterweight to engage the armwhich is attached to a slingand launch projectiles. What is your budget, and what materials do you have access to? These super weapons are the result of over two millennia of trial and error that began with the development of the trebuchet. We launched pumpkins and bowling balls around 10-15 lbs at distances of 300+ feet. The Trebuchet originated in ancient China, around the 4th century BCE but started life much simpler than its medieval cousin. 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. How closely do they match? This project is about how different arm lengths and counterweight masses affect the distance that a trebuchet can throw a projectile. We also use third-party cookies that help us analyze and understand how you use this website. The construction and operation of the counterweight-trebuchet was the province of specialist engineers, who were not always available, and it was ponderous to transport. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123) The Chinese needed so much power for the trebuchet that they had up to 250 solders pulling on ropes to operate the machine [6]. The ballista worked well against troops and cavalry, but had no effect upon walls and structures [2]. This happens when one end of the sling slips off the tip of the swinging arm. [11] Ripcords Trebuchet Stuff. From a 14th century siege (Tlemecen) marble missiles were recovered, the largest had a weight of 230 kilograms (510 lbs). Image by Ron L. Toms. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 277-278) Whereas another scholar notes that modern replicas suggest a range in the order of only 100-120 m, which would be about the same as the traction trebuchet. What are the advantages of a floating arm trebuchet? Figure 2 raises several questions about designing a trebuchet. The Chinese invented the trebuchet in 300BC, the French were . In movies and computer games Trebuchets are often shown as weapons that can destroy city walls and towers easily.

Youll need to cut 8 pieces: Two long base pieces. This counterweight was affixed to the end of the shorter arm and, without the need for ropes and people to pull the machine, space was available for lengthening the sling, which allowed the projectile to go even farther [3]. 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. Next, grab the handles and pivot to the angle you want it to fire at, then press the lever to release the brutal weapon. Unbend one end of a paper clip so it is almost, but not quite, straight. What is the best ratio for a trebuchet? Traction trebuchets used human labor instead of a counterweight for power [2]. To throw the payload as far as possible, how long should the beam be? On a trebuchet, it's much closer to the counterweight. How heavy should the counterweight and the payload be? The projectile is inside a pouch hanging on a sling attached to the long end of a balancing beam.

[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. Defenders used trebuchets against siege towers and the enemy artillery, thus providing what we would call counter-battery fire nowadays. Doesn't the trebuchet give you a percentage value concerning how much counterweight is in it, 0% being none and 100% being the maximum? forcing the projectile out of the leather bag and onto the target. Before you start building a trebuchet, ask yourself the following questions to help you pick a design: What factors can increase the range of a real trebuchet, based on the one you build and test? In order to maximize their chance of winning, both the attackers and defenders employed trebuchets to help their cause. Set out a meter tape starting from the front of the base and lay on 1 The purpose of this paper is to explain the basic functions of a trebuchet, explain subsystems of the trebuchet, and give examples of a few possible modifications to the subsystems. If you search online, there are many different plans and designs for building a trebuchet. While wood is easier to gather, it does consume more wood than reinforcements. The arm then jerks forward and releases the projectile from the sling. the side of the tape the projectile landed, we just looked at the meter tape and 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. Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare 1000-1300. This aspect of warfare has made tremendous advancements throughout history, with current artillery weapons having the capability of sending projectiles past the horizon and landing within a few feet of their intended targets.

It is a hinged counterweight trebuchet in which the counterweight hanger is placed on the top of the arm and the arm is pointed in the forward throwing direction when cocked. Figure 1, below, shows a modern reconstruction of a trebuchet. Thus, the counter-weight trebuchet had to be constructed with a stronger beam, which reduces its effectiveness quite considerably. The horizontal distance the payload would travel is called the trebuchet's range. Any questions? 2020 by History University. Hence, it really depends how one defines as handling and/or operating. First, tape the AA battery to one end of a popsicle stick. m1 is the mass of the counterweight in kilograms (kg). Namely, the Warwolf.

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. Next, press the "Simulate" button located under the inputs. A trebuchet is a medieval stone-throwing war engine. Figure 3, below, shows a sketch that can help you start thinking about how to set up the problem, and the variables involved. The results from this were lackluster. Below are some examples of different materials used as ballast. The earliest trebuchets were traction trebuchets [which] were invented in China in the 5th 3rd centuries B.C.E. [6]. The FAKA is a trebuchet design invented in late 2006 by Craig Macomber. The trebuchet is an ancient siege engine used for throwing large rocks. Launches 25 feet. The word trebuchet has been used for convenience to designate the rotating-beam siege machines, in the full knowledge that other terms were also used in the Middle Ages, and that the question of nomenclature remains unresolved. (Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 271) [5] Wikipedia. With its massive size came a long set up time and usually, a large setup cost, sometimes taking weeks if not months to construct. between leverage and speed of the arm to achieve the highest velocity. 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). A subreddit dedicated to the discussion of Conan Exiles, the open-world survival game set in the Conan the Barbarian universe! General advice is that the optimal ratio is 133:1. Yet, this depictions seems to be a big over exaggerated. (France, John: Western Warfare in the Age of the Crusades 1000-1300, p. 123). The velocity, distance, and trajectory are not only dependant on the ratio of projectile weight to counterweight but also the sling length, cog length and angles, and beam length and angles and counterweight motion. How much counterweight does a trebuchet need? When the counterweight is raised up, it has lots of gravitational potential energy. Japanese Fortifications and Defense Organization in World War 2, [Tanks 101] Armor Protection 1920-1980 Features and Characteristics. of your trebuchet be?

Now, at first look, it may be quite surprising why it took so long to develop the counterweight trebuchet, after all, it seems just a simple improvement, but Hill argues that is not the case. 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. Now, lets examine what happens if we modify the length of the sling by 10% using a parametric sweep. In other words, as long as the release angle is roughly correct, the trebuchet will function as intended. Looking at their advantages and disadvantages, traction trebuchets were probably used for throwing light missiles, whereas the counter-weight trebuchets used for heavy stones. The longer end of the beam would hold the projectile while the shorter end would hold a counter weight [2]. (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) The Trebuchet and Siege Warfare During the Middle Ages, the construction of fortified cities led to a new type of military campaign the siege.

Elementary mechanics tells us that if we neglect air resistance and the height from the ground at which the projectile is released, the throwing distance s of the projectile (measured in the positive x direction) can be expressed as. [13] History Forum. 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. Yet, the highest given number in the records was up to 1200 men, which sounds ludicrously high. The trebuchet was preferred over a catapult due to its greater range capability and greater accuracy. While the trebuchet is bieng launched, time the throw from when the 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.
