The Archimedes Screw also known as a water screw consists of a screw mechanism inside a hollow casing. The screw allowed farmers to salvage water from low areas. It could be rotated using the force of the wind by windmill, or using a lever rotated by hand. The bottom end of the mechanism scoops up water and caries it up the casing to the top of the casing to be transferred to the desired location.

The compound pulley uses two or more pulleys to move a load or an object. An input driver wheel is connected by rope or chain to a follower pulley. When the follower pully is connected to another pulley it becomes the driver pulley for that follower and so on. Archimedes demonstrated the effectiveness by using the system to lift a three-masted ship from the harbor. Previous to the compound pulley system, single pullies were commonly used.

Though calculus as far back as 1820 BC, Archimedes developed the idea further, inventing heuristics which resemble the methods of integral calculus. Archimedes contributed to physics by inventing Archimedes Principle, the law that an object submerged in fluid is acted upwards upon by a force equal to the displaced weight.https://www.bing.com/videos/search?q=archimedes+philosophy&&view=detail&mid=80E99DBA118FFD6CB02480E99DBA118FFD6CB024&&FORM=VRDGAR

The Archimedes Claw also known as the Iron Claw is a weapon designed to defend Syracuse from invading Roman fleets. It consisted of a lever with a claw or a grappling hook that would lift the ship out of the water and drop it onto the water or nearby rocks killing the crew.
