Effective Stress Principle MCQ with answer and solution

The Poisson’s ratio for a saturated clayey soil under undrained loading condition is

Solution

Concept

Poisson's ratio

Step-by-step solution

1. Undrained saturated soil is incompressible, so ν = 0.5.

Explanation

No volume change.

Why the other options are wrong

0.25 and 0.33 are for drained conditions.

Shortcut

Undrained: 0.5.

Correct answer: C) 0.5
