1.7.3. Angle of Repose

Try these first

1. 1.

   Define Angle of Repose in your own words.

   Hint

   Think about the stability of slopes.

2. 2.

   Name one factor that influences the Angle of Repose.

   Hint

   Consider materials and their characteristics.

3. 3.

   What is the Angle of Repose?

   • The angle of stability for a slope
   • The maximum compressive strength of soil
   • The minimum cohesive value

   Hint

   Think about slope stability.

4. 4.

   True or False: The Angle of Repose is influenced by particle shape.

   • True
   • False

   Hint

   Consider why certain shapes interlock better.

5. 5.

   A hill made of sand has a 30-degree Angle of Repose. If it rains, what changes could cause it to fail?

   Hint

   Consider the impact of water on soil properties.

6. 6.

   Calculate the potential failure angle of a slope made of angular gravel versus round gravel. Discuss how the types of particles influence stability.

   Hint

   Reflect on how shapes interact.
