The winch allows a person to put a great deal of energy into the catapult over a period of time. The five types are the Ballista, the Trebuchet, the Mangonel, the Springald and the Onager. Electromagnetic catapults are also expected to require significantly less maintenance through the use of solid state components. An aircraft catapult is a device used to allow aircraft to take off from a very limited amount of space, such as the deck of a vessel, but can also be installed on land-based runways in rare cases.

Pumpkin chunking is another widely popularized use, in which people compete to see who can launch a pumpkin the farthest by mechanical means (although the world record is held by a pneumatic air cannon). type of catapult is probably not the one most of us envisiona torsion catapult that throws stones to break down enemy walls, but an early version of the Medieval crossbow that shot missiles when the trigger was released. 49-60. Different means have been used to propel the catapult, such as weight and derrick, gunpowder, flywheel, air pressure, hydraulic, and steam power, and solid fuel rocket boosters. Catapults come in several basic forms. Sometimes they used flax. Britannica does not review the converted text. 208-212. There are five historical types of catapults: the mangonel, onager, ballista and trebuchet, using three types of motive force: tension, torsion and gravity. Various types of Catapults have been used by the Greeks, Romans, and Chinese. Each of these catapults would build up potential energy through the use of a winch that was designed to slowly pull back a heavy string or fabric. Campbell, Duncan (2003), Greek and Roman Artillery 399 BC AD 363, p.3". Most people are not aware of how important this invention is.

On gas-turbine powered ships, an electromagnetic catapult would eliminate the need for a separate steam boiler for generating catapult steam. Primitive catapults were essentially "the product of relatively straightforward attempts to increase the range and penetrating power of missiles by strengthening the bow which propelled them". The result of this analysis produces an equation for the distance R a projectile will travel if released with a given initial velocity v0 at a specified angle with respect to the ground: If you experiment with different values for the launch angle, you find that the value of sin 2 has its greatest value, 1, when is 45 degrees. Soldiers also used catapults to fling spears at an advancing army. However, setting up these trebuchets took upwards of a week, and as a result, sieges became extremely long and complex processes.
