5 cards from this lesson. Good the night before a test.
Try these first
- 1.
What is shear strength?
Hint
Think about the forces that act on particles in soil.
- 2.
What two components make up shear strength?
Hint
One is about bonding and the other about movement.
- 3.
What is the main purpose of shear strength?
- To connect soil particles
- To resist sliding forces
- To absorb water
Hint
Think about forces acting on structures!
- 4.
The angle of internal friction is...
- True
- False
Hint
Relate it back to sliding and stability.
- 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.
Hint
Remember to use the angle in degrees.
- 6.
Discuss how shear strength is affected by water saturation in soil, providing examples.
Hint
Consider real-world events and how they relate to soil behavior.
