Try these first

1. 1.

   What is one factor that influences the shear strength of soil?

   Hint

   Think about what makes up the soil.

2. 2.

   Name a term used to describe a loose soil state.

   Hint

   Consider terms related to soil density.

3. 3.

   Which factor does NOT influence shear strength?

   • Soil composition
   • Initial state
   • Air pressure

   Hint

   Consider what physical aspects relate to the soil's internal properties.

4. 4.

   True or False: The Mohr-Coulomb failure criteria states that shear stress alone determines soil failure.

   • True
   • False

   Hint

   Think about how stress types interact.

5. 5.

   An engineer needs to evaluate the shear strength of a soil sample from a construction site with both saturated and unsaturated layers. Which tests would you recommend and explain their relevance?

   Hint

   Consider the specific types of soil present at the construction site.

6. 6.

   A project involves a slope with varying degrees of soil density. How would you approach calculating the potential slip surface using Mohr-Coulomb criteria?

   Hint

   Focus on how density changes impact shear strength.
