-==Soil mechanics==
-Soil mechanics is a key area of geotechnical engineering. Soils are made up of solid rock or mineral particles, water, and air. These three are known as the phases of soil. There are a number of standard properties of soil which are used in geotechnical engineering:
-*Unit weight: the weight of a unit volume of soil.
-*Voids ratio: the ratio of the volume of voids (V<sub>v</sub>) to the volume of solids (V<sub>s</sub>).
-**Porosity: the ratio of the volume of voids (V<sub>v</sub>) to the volume of the soil.
-*Shear strength: the shear stress which causes the soil to fail.
