Challenge Problems
Push your limits with challenges.
Question 1
A civil engineer needs to build a wall on sandy soil with a cohesion of 4 kPa and an internal friction angle of 25 degrees. What precautions should be considered regarding shear strength?
💡 Hint: Consider how the soil might shift under pressure.
Question 2
Design a foundation for a structure weighing 200 kN on clay that has a cohesion of 10 kPa. Assuming an angle of internal friction of 20 degrees, calculate the required area of the foundation base to prevent shear failure.
💡 Hint: Think about how applied load translates to stress over an area.
