Question 1.
Define shear strength in your own words.
Show hintHide hint
Think about the sliding or shearing forces acting on the soil.
Question 2.
What are the two main components of shear strength?
Show hintHide hint
One deals with sticking and the other with sliding.
3Question 3.
What is shear strength?
- A measure of soil density
- The capacity to resist sliding
- The weight of the soil
Show hintHide hint
Consider what happens when forces try to make the soil slide.
4Question 4.
True or False: Frictional resistance is a stress-independent property.
- True
- False
Show hintHide hint
Remember the role of stress in friction.
Question 5.
A saturated slope has a cohesion of 10 kPa and a normal stress of 30 kPa. Calculate the expected shear strength.
Show hintHide hint
Don't forget to convert the angle to radians if needed.
Question 6.
In a landslide scenario, analyze how decreasing cohesion affects the slope safety factor given a normal stress of 20 kPa.
Show hintHide hint
Evaluate how lower cohesion shifts the stability balance.
