CATAPULT
WHAT IS A CATAPULT ?A catapult is
a ballistic device used to launch 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. In modern times the term can apply to
devices ranging from a simple hand-held
implement (also called a “slingshot”) to a
mechanism for launching aircraft from a ship.
Types of Catapult1. The Single Arm Catapult
The single arm catapult would use a ratchet system to move the swing arm into place, locking securely with each toothy click so that accidental ejection could be avoided.
2. The Double Arm Catapulta worm gear system winding a very large wheel would be used to gradually set the throwing arm into its final firing position.
Uses Of Catapult• This machine would undoubtedly have wrought
havoc upon any castle/fort it attacked. • It could be reloaded and retightened very quickly.• As with all medieval catapults, the soldiers may
have decided to fire flaming ballistics or even disease-ridden dead bodies into the castle they were attacking – this usually spread either fire or disease very quickly within the walls of the target castle/fort.
Design Drawbacks1. Creating a better, more durable steel leaf
proved challenging due to the need to flex so many large sections of steel into layers.
2. The considerable cost to produce the steel mechanism was too high.
He is famous with his paintings such as Last Supper and Mona Lisa. But Leonardo worked in many areas. He worked as a sculptor, architect, military engineer. He has made anatomical studies with corpses.
