The catapult dates all the way back to 400 be when it was invented in the Greek town of syracus. The main types of catapults are trebuchet, mangonel, onager and ballista. There are many more types of catapults also. Catapults were an absolute revelation in weaponry. Although they are very hard to create, they use very simple forms of physics to complete their task of destruction. The catapult has a basket on the end of a movable arm strong enough to hold the weight of the object it is intended to hurl. Tension is applied to the arm, which is forced down and then locked in place. People in ancient times used twisted ropes to create tension. Then the object needing to be hurled is thrown up in the basket and then line is then cut causing the arm to fly to the other side launching whatever it is (fire balls) at its intended target. Distance was controlled simply by how tight the roped was coiled up. Catapults however had downsides they were not very accurate and during the rain they could not be used plus they were very large and hard to transport. The idea of a catapult came from the invention of the crossbow, which is significantly smaller but uses some of the very same aspects. Catapults where used to throw hot sand to get between the armor of enemy knights also they were used to throw hot tar to attack there enemies. The catapult is one of the first types of biological warfare it was used to launch infected bodies into enemy camps to spread disease. Catapults where great advance in the advancement of
