Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for the 'A' line on the plasticity chart?
- I_P = 0.73(W_L - 20)
- I_P = 0.5(W_L + 10)
- I_P = 0.3(W_L - 30)
💡 Hint: Think about how we derived it during class.
Question 2
True or False: A higher plasticity index indicates a more plastic soil.
- True
- False
💡 Hint: What does plasticity index measure in terms of soil behavior?

Challenge Problems
Push your limits with challenges.
Question 1
Given a soil sample measured: Liquid Limit = 62%, Plastic Limit = 32%, and moisture content = 48%. Determine its classification and liquidity index.
💡 Hint: Don’t forget to apply the index formulas correctly to classify the soil.
Question 2
A researcher finds a soil with 45% liquid limit, 25% plastic limit, and 80% clay content. Calculate its activity and suggest possible implications if used for construction.
💡 Hint: Use the ratios properly to assess the suitability of the soil.
