A slingshot or catapult is a small hand-powered projectile weapon. The classic form consists of a Y-shaped frame, with two tubes or strips made from either a natural rubber or synthetic elastic material. These are attached to the upper two ends. The other ends of the strips lead back to a pouch that holds the projectile. One hand holds the ...
The EMALS uses a linear induction motor (LIM), which uses alternating current (AC) to generate magnetic fields that propel a carriage along a track to launch the aircraft. [5] [6] The EMALS consists of four main elements: [7] The linear induction motor consists of a row of stator coils with the same function as the circular stator coils in a conventional induction motor.
A trebuchet [nb 1] (French: trébuchet) is a type of catapult [5] that uses a rotating arm with a sling attached to the tip to launch a projectile. 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 ...
Onager with a bowl bucket Sketch of an onager with a sling, a later improvement that increased the length of the throwing arm, from Antique technology by Diels.. The onager (UK: / ˈ ɒ n ə dʒ ə /, / ˈ ɒ n ə ɡ ə /; US: / ˈ ɑː n ə dʒ ə r /) [1] was a Roman torsion-powered siege engine.
Basic diagram of an onager, a type of catapult. A catapult is a ballistic device used to launch a projectile a great distance without the aid of gunpowder or other propellants – particularly various types of ancient and medieval siege engines. [1] A catapult uses the sudden release of stored potential energy to propel its payload.
The Onager was a Roman torsion powered siege engine. It is commonly depicted as a catapult with a bowl, bucket, or sling at the end of its throwing arm. Trebuchet: 4th Century BC China: Similar to the catapult, but uses a swinging arm to launch projectiles. It is usually considered to be stronger than the catapult. [4] Oxybeles: 375 BC Greece
That's going to be a hard no from me 😬
The torsion mangonel myth began in the 18th century when Francis Grose claimed that the onager was the dominant medieval artillery until the arrival of gunpowder. In the mid-19th century, Guillaume Henri Dufour adjusted this framework by arguing that onagers went out of use in medieval times, but were directly replaced by the counterweight trebuchet.
