When the screw is rotated on its axis of rotation in the proper direction, the cupped water is lifted up along the underside of the beam on the moving threads until it reaches and weed flow out of the tubes raised end. This simple machine makes motion more convenient as it can be utilize in many shipway to multiply push back (decrease the lather needed to do the job). In the Archimedes screw because it is perpetual in movement the effort required to transport the water is reduced.

PART 3 Archimedes screw was first utilize by the Egyptians for irrigation and by the Romans for water supply systems, irrigation and drainage prepare. It also found work in the ore mines of Spain.
