Answer: D. Clays
The angle of internal friction is least for clays.
Solution
The Angle of Internal Friction is least for clays.
The maximum resistance shown by the soil just before failure is called Shear Strength.
The equation for the shear stress is given by Coulomb.
S=C + σ tan Φ
Where,
S – Shear Strength of Soil
C – Cohesion of the Soil
σ – Normal Stress on the Plane
Φ – Angle of Internal Friction
Different types of soil based on C and Q values:
1. C – Φ soil
C ≠ 0
Φ ≠ 0
2. Cohesionless Soil
C = 0
Φ ≠ 0
3. Cohesive Soil
C ≠ 0
Φ = 0
