An easier way to answer this is 'what didn't they throw'. The main advantages of the traction trebuchet were that it was faster and cheaper to build and needed no specialists, unlike the counterweight trebuchet. See gravitational potential energy. Can you pick these parameters based on hand calculations or computer simulations (above), or based on design information you found through your own research?

The FAKA is very efficient for its frame height and arm length as well. Kaffa was a port city, so the disease soon spread across the Mediterranean and into European ports [3]. The main beam measures 54 "workfeet," or 15.55 m, with a throwing arm of 46 "workfeet," or 13.248 m. One is the frame, one is the swing arm, and one is the set of moving parts. [4] Trebuchet.com.

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 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. Sling The sling is attached to the long end of the swing arm lever and holds the projectile that is to be thrown. Now, since we covered that part, lets get started. .

The quantity s is shown along the projectile trajectory, and it represents the throwing distance that would follow from releasing the projectile at a certain point on this trajectory. Read the relevant section(s) below for ideas on how to get started on your project. The further between . One of the main difference to the traction trebuchet is the fact that a lot of force is applied on the beam, when the trebuchet is readied and held in position.

(Hill, Donald R.: Trebuchets, in: France, John: Medieval Warfare, p. 280-282) 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. This machine could throw stones up to 100 meters, but was not very accurate, given the inherent inconsistency in using true manpower. The catapult operator would twist ropes that surrounded the pivoting arm, causing immense tension. You also have the option to opt-out of these cookies. 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 . 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 fixed counterweight eventually gave way to a hinged counterweight (Fig. The ratio between the counterweight and the payload is important, and this may dictate the size of your trebuchet.

For an outdoor trebuchet, you can use 2 x 4-inch (5 x 10 cm) planking. CW stands for counterweight, and the release . More About scull_mech This is a general description of how to create a floating arm (f2k) trebuchet. The horizontal distance the payload would travel is called the trebuchet's range. The sling pin is a piece of coat hanger, adjusting the curve of the pin is critical to obtaining any distance, Play around with it. General advice is that the optimal ratio is 133:1. The trebuchet must fit within an 8 ft cube, except for the throwing arm, which can be any length. Thus, sometimes stones were transported a long way: This abbreviated engineering project idea will help you get started with three different ways to investigate what factors can increase the range of a trebuchet: You can decide whether you want to try just one, two, or all three of these approaches. The long sling, basically provided an almost weightless extension of the beam, thus providing the additional force that compensated for the increased weight of the beam. 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. 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 . There is more than one way to tackle the problem. Enjoy! The Wikipedia page on trebuchets links to a PDF paper which discusses exactly this question. 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.
