Question

The range of Poisson’s ratio μ for loess is _________

(a) 0.1-0.3

(b) 0.4-0.5

(c) 0.3-0.35

(d) 0.9-1

I had been asked this question during an interview.

This question is from Generalised Hooke’s Law topic in division Elements of Elasticity of Geotechnical Engineering I

Answer 1

Right option is (a) 0.1-0.3

The best I can explain: The range of Poisson’s ratio μ for loess is 0.1-0.3. The range of Poisson’s ratio μ for unsaturated clay is also 0.1-0.3. For saturated clay it is 0.4-0.5. For silt it is 0.3-0.35.
