Question: What is the typical range of the angle of internal friction for sandy soils?

Options:

Correct Answer: 30° to 45°

Solution:

The angle of internal friction for sandy soils typically ranges from 30° to 45°, which is important for assessing shear strength.

What is the typical range of the angle of internal friction for sandy soils?

What is the typical range of the angle of internal friction for sandy soils?

Step 1: Understand what angle of internal friction means. It is a measure of how much resistance a soil has to sliding or shearing.
Step 2: Know that sandy soils are a type of soil that consists mostly of sand particles.
Step 3: Learn that the angle of internal friction for sandy soils is usually between 30 degrees and 45 degrees.
Step 4: Recognize that this angle is important because it helps engineers and geologists understand how strong the soil is and how it will behave under pressure.
