Archimedes’ Screw

Archimedes’ Screw
The purpose is to move water uphill to help with irrigation.

Contributions:
Crop irrigation and drainage/farming practices
Remove water from ships so they would not sink (mechanical water pump)
Move sludge
Sewage plants (many substations send to main treatment plant)

The Law of Hydrostatic

Simple Machines:
Law of the Lever

Law of the Lever – the closer the lever is to the fulcrum, the easier it is to move an object

Contributions:
Applied mechanics – moving from physical science theory to technology and it is used to explain the effects of items when force is applied
(example: engineering)
