Where was it invented and who invented it?

The Trebuchet was invented in ancient China during the 4th century.  Documents were made of it in 1324, which the french engineer Renaud Beffeyte built his modern version from in 1984.

Who originally made the trebuchet?

There are no documents of who exactly made the trebuchet, the only recorded that ancient Chinese built the first working trebuchet.

When was the trebuchet invented?

There are different variations of when exactly it was invented, but 4th century china.

Why was the trebuchet invented?

The trebuchet was built with the intention of throwing projectiles in sieges and battle. Warfare was greatly enhanced by the trebuchet because it made a stepping stone for more advanced technology.

What were the short and long term implications of the trebuchet?

Short term implications would be destruction during battles and wars becoming more aggressive. In the long term, the trebuchet was a very successful invention that increased designs for more advanced warfare technology.

The physics behind it:

This diagram shows the physics behind the trebuchet. The trebuchet runs on kinematics, and different energies. When loaded and at rest, the machine has potential energy that sits in the sling. When loaded and flung, the kinetic energy is pulled into play, replacing the potential. Once released, the object that is being thrown, in this instance is forced through the air by the acceleration of the bar that hold the sling in place. When the object reaches a constant velocity. The velocity depends on how fast it is released, which depends on the mass of the counter weight. The counterweight pulls the bar down on one end,

Which then creates a chain reaction; Counterweight released, bar pulled down, sling is flung up, load is released from sling into constant velocity, and finally the load coming with impact on its target (hopefully). The trebuchet also contributes to Newton’s Third Law of Motion which is as follows: “For every action there is an equal and opposite reaction”. .

If we were to use formulas and equations, a possible way to do so would be to find the  that the trebuchet does,  (½ ⋅ m ⋅ v²) would find the kinetic energy. You would need to do some runs to see what it velocity is, or you could use the initial velocity which should be 0 m/s.
