Challenge Problems
Push your limits with advanced challenges
A direct shear test is carried out at various normal loads: 50 kPa, 100 kPa, and 150 kPa, yielding shear stresses of 25 kPa, 45 kPa, and 75 kPa respectively. Determine the friction angle (ϕ).
💡 Hint: Find the slope from the shear stress and normal stress relationship.
Discuss the effects of moisture content in a Direct Shear Test on sandy soils. How might this affect results?
💡 Hint: Consider how water interacts with soil grains.
