What is shear strength?
Think of it as the 'grip' of the soil.
Name one factor that affects soil composition.
Consider the materials that make up the soil.
What factor does NOT affect shear strength?
Color does not change how soil behaves under stress.
True or False: Higher density in soil experiences more shear strength compared to lower density.
Think about compact vs loose materials.
Given a soil sample with known mineral content and pore fluid properties, calculate its expected shear strength using the Mohr-Coulomb criteria under varied loading conditions.
Remember the formula: τ = c + σ * tan(φ) where τ is shear strength.
Evaluate the implications of using a dense clay versus loose sand at a construction site. Determine how their initial states affect load-bearing capabilities.
Think about how each behaves under weight.
