Question 1.
What is shear strength?
Show hintHide hint
Think about the forces that act on particles in soil.
Question 2.
What two components make up shear strength?
Show hintHide hint
One is about bonding and the other about movement.
3Question 3.
What is the main purpose of shear strength?
- To connect soil particles
- To resist sliding forces
- To absorb water
Show hintHide hint
Think about forces acting on structures!
4Question 4.
The angle of internal friction is...
- True
- False
Show hintHide hint
Relate it back to sliding and stability.
Question 5.
A soil sample has an internal friction angle of 36 degrees and a cohesion of 15 kPa. If the vertical stress on the soil is 25 kPa, calculate the shear strength.
Show hintHide hint
Remember to use the angle in degrees.
Question 6.
Discuss how shear strength is affected by water saturation in soil, providing examples.
Show hintHide hint
Consider real-world events and how they relate to soil behavior.
