Question 1.
What is dry sieve analysis used for?
Show hintHide hint
Think about the physical properties of soil.
Question 2.
Why must fine particles be removed before dry sieve analysis?
Show hintHide hint
Consider the size of the particles of interest.
3Question 3.
What particle size is typically separated using dry sieve analysis?
- Larger than 75 microns
- Smaller than 75 microns
- Only clay-sized particles
Show hintHide hint
Recall the definition of dry sieve analysis.
4Question 4.
True or False: The uniformity coefficient is calculated by the size at 60% finer by weight.
- True
- False
Show hintHide hint
Think about how we determine soil uniformity.
Question 5.
A soil sample retains 40% on a 1 mm sieve, 30% on a 2 mm sieve, and 20% passes through this sieve. How would you interpret the uniformity coefficient?
Show hintHide hint
Identify the D values corresponding to the 60% and 10% thresholds.
Question 6.
Compare the behavior of soil with a Cu of 10 versus a Cu of 2 in engineering applications. Which is preferable and why?
Show hintHide hint
Think about how particle size affects soil compaction and support.
