Q8
What is the role of cohesion in soil mechanics?
A.
Controls drainage
B.
Provides shear strength in absence of friction
C.
Affects permeability
D.
Enhances compressibility
E.
2
Solution
Answer: Option
Solution:
Cohesion is the internal molecular attraction between soil particles, especially in clays.It contributes to shear strength when friction is minimal, like in saturated clays.
