Question 1
What is the Mohr-Coulomb failure criterion used for?
- To measure earthquake magnitude
- To analyze fault behavior under stress
- To categorize types of faults
💡 Hint: Remember, it's not about measuring but understanding fault behavior.
Question 2
True or False: Normal stress always acts parallel to the fault surface.
- True
- False
💡 Hint: Think about the definition of normal compared to shear stress.

Challenge Problems
Push your limits with challenges.
Question 1
In an area where the shear stress is 50 MPa, the friction angle is 25 degrees, and the normal stress is 30 MPa, will the rocks fail according to the Mohr-Coulomb failure criterion?
💡 Hint: You may need to assume a value for cohesion or check if it's provided.
Question 2
Describe a scenario wherein a fault remains locked despite accumulating stress and the implications for nearby structures.
💡 Hint: Consider the concept of strain energy and sudden releases.
