**CE8491 SM SOIL MECHANICS**

1. Define soil?

Weakly cemented accumulation of mineral and organic particles and sediments found above the bedrock, or unconsolidated material consisting of discrete solid particles with flui or gas in the voids.

2. Define Soil Mechanics.

According to (ASTM) Soil Mechanics it is define as the application of the laws and principles of mechanics and hydraulics to engineering problems dealing with soil as an engineering material.

3. Define Void Ratio

The void ratio of a soil is defined as the ratio of volume of voids to the volume of solids.

4. Define specific gravity.

It is defined as the ratio of the mass of a given volumes of solid gains to the mass of equal volume of water at the same temperature

5. Define Density

The density of a substance is the mass per unit volume of that substance. For water this is denoted by w, and its value is about 1000 kg/m3. Small deviations from this value may occur due to temperature differences or variations in salt content. In soil mechanics

these are often of minor importance, and it is often considered accurate enough to assume that w = 1000 kg/m3
