This simple machine makes plow more convenient as it can be used in many ways to multiply impact back (decrease the effort needed to do the job). In the Archimedes screw because it is uninterrupted in movement the effort required to direct the water is reduced.

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