2. What is the Mohr-Coulomb failure criterion?
- Slope failure occurs on a critically oriented plane when gravitational shear stress on the plane exceeds the shear strength given by tf=c + o tan.
- Slope failure occurs on a critically oriented plane when gravitational shear stress on the plane is less than the shear strength given by tf=c + o tan.
- Slope failure occurs on a critically oriented plane when rotational shear stress on the plane exceeds the shear strength given by tf=c + o tan.
- Slope failure occurs on a critically oriented plane when gravitational shear stress on the plane exceeds the shear strength given by tf=c + a tan.
