Medieval Siege Engines

The article talks mainly about medieval siege engines and the advancements in siege engine technology. The discussion of siege engines focuses mainly on the advantages of the counterpoise engine, which uses gravity and a counterweight to launch projectiles, and how its structure is superior to the more ancient torsion siege engine. For example, a counterweight engine has a smooth projectile arm action, which is a lot more effective and less damaging to the engine than the jerky, inconsistent action of the torsion engine. The article also briefly discusses how the improvements in siege engines spurred improvements in the strength and durability of castles and castle structures. This is one of the reasons medieval age castles still stand today - because they were built to withstand projectiles launched at high speed by the most advanced siege engines of the time.
