Challenge Problems
Push your limits with advanced challenges
A construction site has three soil samples: one with a relative density of 30%, another at 50%, and the last at 70%. Determine which sample is likely to have the highest angle of friction and explain why.
💡 Hint: Think about how density influences resistance to sliding.
If a geotechnical analysis reveals an angle of friction of 45 degrees for a specific coarse-grained soil at a relative density of 75%, what implications does this have for a new foundation?
💡 Hint: Consider the relationship between load capacities and stability.
