The specialists who constructed this were purportedly called ‘onager-neers’ which eventually became ‘engineers’. One particular type of catapult was the ‘onager’ – this was named after a type of wild donkey that was well-known for having a vicious kick. When laying siege to towns and castles, it was common practice for skilled specialists to build catapults in an attempt to break down defences and demoralise the defenders. The word ‘engineer’ was originally used to describe people responsible for building siege weapons in ancient times. The principles of levers are also used in many applications when designing sports equipment, such as cricket bats, golf clubs and hockey sticks. These include pliers, scissors, brake pedals and wheels and axles. Levers are one of the simplest machines and are used in many applications. Pencils (or similar, such as dowel rods).
