An Archimedean screw is another name for an Archimedes' screw, a screw which, when twisted inside a cylinder, raises water from a lower level to a higher level, allowing irrigation of fields.
The main parts of a screw include: Head: The top part of the screw that is usually slotted or Phillips-shaped for turning with a screwdriver or drill. Shank: The cylindrical body of the screw that has threads wrapped around it. Threads: The spiraled ridges on the shank that grip and secure materials when the screw is turned. Point: The sharp or tapered end of the screw that facilitates easy penetration into materials. Root: The bottom of the threads, where they meet the shank. Length: The measurement from the tip of the screw to the bottom of the head. These components work together to fasten materials by turning the screw into them
Archimedes of Syracuse invented the water screw, and Sir Joseph Whitworth invented the first standard screw thread system.
The screw is not only a fastener. The screw can lift grain to high places, lift water, be used with another screw to drive machinery (called gears) They are needed to accurately machine and build machinery So nothing you own, eat or play with would be here without the screw.
