Introduction

A catapult is a device used to throw or hurl a projectile a great distance without the aid of explosive devices—particularly various types of ancient and medieval siege engines. Although the catapult has been used since ancient times, it has proven to be one of the most effective mechanisms during warfare.The catapult answered humanity's need to propel a missile effectively over a great distance with some "mechanical" assistance. Since ancient times, the style and size of this device has varied. But the main usage has always been some form of attack on a target, mostly in times of warfare.
