Question
**Problem Set** 2. **Prove**: \( n = \frac{e}{1+e} \) and \( e = \frac{n}{1-n} \) based on definitions of void ratio and porosity. 3. **Classify the following soils according to the Unified Soil Classification System**: Group symbols and typical names. | Soil | Percent passing U.S. sieve | LL | PL | |------|-----------------------------|----|----| | | No. 4 | No. 10 | No. 20 | No. 40 | No. 60 | No. 100 | No. 200 | | A | 95 | 86 | 65 | 52 | 46 | 38 | 25 | 38 | 22 | | B | 100 | 98 | 95 | 88 | 82 | 75 | 65 | 65 | 58 | **Explanation of the Table**: - This table presents the sieve analysis of two soil samples, A and B, with corresponding percentages passing through standard U.S. sieves (No. 4, No. 10, No. 20, etc.). - It also includes the Atterberg limits: Liquid Limit (LL) and Plastic Limit (PL) for each soil sample. - These parameters are essential for classifying the soil types according to the Unified Soil Classification System (USCS).
