Question 2.
Define Swelling Index.
Show hintHide hint
Consider how plants absorb water.
3Question 3.
What is the definition of compressibility?
- Ability to resist pressure
- Ability to soften
- Ability to reduce volume under stress
Show hintHide hint
Think of how a sponge compresses.
4Question 4.
True or False: The Swelling Index measures how much a material contracts when wet.
- True
- False
Show hintHide hint
Remember absorption vs. release.
Question 5.
A material has a compressibility of 0.001 m²/N. If a force of 1000N is applied, calculate the expected volume reduction if its original volume was 1m³.
Show hintHide hint
Use the formula for volume reduction based on compressibility.
Question 6.
How would you compare the behavior of clay and sand under the same level of moisture? Discuss in regards to their Swelling Index and compressibility.
Show hintHide hint
Consider their physical properties and how they react to moisture.
