The Archimedean screw can be constructed using two simple ideas. The first is a screw, which in an inclined plane wrapped around a central core or axis. The second idea is to closely confine the screw by placing it inside a cylinder the length of the screw.
One variation of the Screw is to coil a flexible tube around a core shaft. As the shaft is turned, the tube will work in the same way and lift the water up, with the problems caused by an actual Screw's operation.
A picture is probably worth a thousand words at this point, so drop down below and find a link to an explanation of the device. It comes complete with an aplet showing the the machine in operation. Check out how it is set up and how it works.
It is one simple piece it does not need multiple pieces to make it.
The trick to designing a screw pump is to set the slope of the shaft so that the water caught in the flanges in constantly flowing uphill. ADDED: Assuming this means the Archimedean Screw, a screw thread is essentially an inclined-plane wound into a helix, so it acts rather like a long wedge in raising the material it is acting on. For raising a fluid the screw also needs to be a suitably close fit in its cylinder to minimise leakage round the thread crest.
stating the Archimedean Principle.
yes
Archimedes. So the story goes. He was in the bath one day, and the water did not flood over the edge of the bath. However, on another day the bath was full to the brim. He gets in and notices the water splash out. That's where the water went. He run's down the street shouting 'Eureka, I have found it!!!!' So today we have the Archimedean Principle ; 'The weight of a body immersed in a fluid is equal to the weight of the fluid displaced'. I learnt that at school at the age of 11 years. Archimedes also gave us the 'Archimedean Screw' for lifting water, and polished brass shields, against the Sun, to Blind the Enemy.
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.
Its Purpose was to irrigate and lift water From mines and Ship Bilges
The Water Screw helped to bring water from a lower level to a higher one. :)[ADDED] It's normally called the "Archimedean Screw".
The twist drill uses flutes that act as an Archimedean screw to lift swarf from the hole.

An Archimedean ordered field is an ordered field which satisfies the axiom of Archimedes.
what are the differences between platonic and archimedean solids? physically , naturely and features

An Archimedean property is the property of the set of real numbers, that for any real number there is always a natural number greater than it.
No, Archimedes did not invent the lawn mower even though one of his attributed inventions paved the way for that invention 2,000-plus years later. The lawn mower invented by an English textile mill engineer in 1830 had the name Archimedean revolving cutter mower. The mower in question included a revolving screw-shaped blade inside a cylinder, considered the essential design of the Archimedean screw attributed to Archimedes' (287 B.C.-212 B.C.) inventiveness.
