Challenge Problems
Push your limits with advanced challenges
A soil sample shows D10 = 0.02 mm, D30 = 0.1 mm, and D60 = 0.5 mm. Calculate the uniformity coefficient (Cu) and curvature coefficient (Cc).
💡 Hint: Remember the formulas for Cu and Cc.
You have two soil samples: Sample A with a straight grading curve and Sample B with a curved grading curve. Discuss the engineering implications of each sample based on its grading characteristics.
💡 Hint: Consider how the shape of the grading curve affects soil behavior.
