What is shear strength in your own words?
Think about what keeps the soil particles together.
Define cohesion.
Consider attractions between soil particles.
What defines the shear strength of a soil?
Focus on how soil behaves under stress.
Cohesion is dependent on external stress. (True/False)
Think about what holds particles together without external influence.
Given a soil sample with cohesion of 12 kPa, an internal friction angle of 25°, and normal stress of 50 kPa, calculate the shear strength.
Ensure to identify the values correctly from the problem statement.
Discuss how increasing water content impacts shear strength in granular soils and its implications for construction.
Think about how saturated soil behaves differently from dry soil.
