Tongue depressor. A tongue depressor or spatula is a tool used in medical practice to depress the tongue to allow for examination of the mouth and throat. Hobbyists, artists, teachers and confectionery makers use tongue depressors, which may also be referred to as craft sticks or popsicle sticks.
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.
An ice pop stick bomb, ready to throw. Stick bombs can be constructed out of most flat sticks of the appropriate dimensions. The usual material for construction is wood, but plastic can also be used. Ice pop sticks (craft sticks) and tongue depressors are popular because of availability, low cost, and because they are easily coloured. Tongue ...
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 ...
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 ...
On some of the reliefs of the Pyramid of Sahure (V dynasty, c. 2500 BC); [228] the images and explanatory captions are particularly precise and accurate in their depiction of what seems to be military training using sticks. Tahtib, with archery and wrestling, was then among the three disciplines of warfare taught to soldiers.
The catapult operator then pushes a button to fire the catapult. Once the catapult fires, the hold-back breaks free as the shuttle moves rapidly forward, dragging the aircraft by the launch bar. The aircraft accelerates from zero (relative to the carrier deck) to about 150 knots (280 km/h; 170 mph) in about 2 seconds.
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.
