Question 1

What parameters does the Mohr-Coulomb criterion depend on?

  • Only cohesion
  • Cohesion and angle of internal friction
  • Only normal stress

💡 Hint: Look back at the equation we discussed.

Question 2

True or False: Cohesion is a property that varies significantly between different types of soils.

  • True
  • False

💡 Hint: Recall the examples of cohesive soils like clay versus granular soils.

Challenge Problems

Push your limits with challenges.

Question 1

A geotechnical engineer conducts a triaxial test on a soil sample that shows a cohesion of 15 kPa and a friction angle of 25°. Calculate the shear strength when the normal stress is 80 kPa.

💡 Hint: Work through the equation step-by-step.

Question 2

A construction site on sandy soil has been found inadequate for supporting a foundation based on Mohr-Coulomb failure criteria. Discuss what soil properties might be problematic and suggest solutions.

💡 Hint: Consider how different types of soil interact under pressure.
