Today they are strongly associated with the medieval period in Europe.Ī trebuchet is just one type of catapult-other forms of catapults were used long before trebuchets were invented. Trebuchets have been used for centuries, including in ancient China. Invaders would park their trebuchets outside of an enemy castle and hurl huge rocks (among other things) to destroy the structure. The word engine refers to a piece of military machinery, and siege refers to an assault on a city or fortress. Trebuchets were historically used in what historians sometimes call siege engines, a weapon used to break down massive structures, like castle doors or walls. (In early versions of the trebuchet, that force was created by soldiers pulling down on the contraption, instead of by a weight.) Designs vary, but a trebuchet typically consists of a platform, a pole with an attached sling containing the projectile, and a counterweight-an even heavier object that is hoisted up and then dropped, raising the pole and creating the force necessary to launch what’s in the sling. The defining characteristic of a trebuchet is its use of the power of gravity. What is a trebuchet?Ī trebuchet is a machine for hurling projectiles using a sling. A trebuchet is a specific type of catapult that’s gravity-powered-it uses a counterweight that pulls down and rapidly raises another part that then flings the object from a sling. There are different kinds, but the most common involves a long arm pulled back and then forcefully released to launch a large object.
⚡ Quick summaryĪ catapult is a machine for hurtling projectiles. They are and they aren’t, but don’t worry-we’ll break down the differences in the design, physics, and functionality of trebuchets and catapults. Do you need a trebuchet? A catapult? Are they the same thing? Or perhaps you find yourself desiring to fling an enormous pumpkin an absurd distance.
So, a large boulder has just been hurled at you with a medieval-looking contraption and, understandably, you want to know what it is. For all other inquiries, we’re glad to help. If a large projectile is currently hurtling toward you, move out of the way before reading any further. I recommend deleting this article from Wikipedia.Welcome to the Trebuchet and Catapult Helpline. I think catapult effect is obscure nomenclature, and unnecessary because we have the Lorenz Force Law. But one hit says that "Catapult effect" is a synonym for "motor effect"Įlectric_motor#Force_and_torque This Wiki article talks about this force as the result of the Lorenz Force Law. A google search provides a very small number of hits.
