## Specific Objectives for Chapter I

### Fundamental :

- Define key soil mechanics terms and sources of shear strength in soils

- Explain the Mohr-Coulomb failure criterion and its role in determining soil shear strength.

- Construct Mohr's Circle to analyze 2D stress states and identify principal stresses (σ₁, σ₃).

- Determine shear strength parameters (c and φ) from laboratory test results.

- Interpret stress-strain curves from triaxial tests to identify failure conditions.
