Question

The modulus of elasticity in MPa for very soft clay is __________

(a) 2-15

(b) 15-60

(c) 50-81

(d) 100-200

This question was addressed to me during an interview for a job.

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

Answer 1

Right answer is (a) 2-15

The best explanation: The modulus of elasticity in MPa for very soft clay is 2-15 MPa. For loess it is 15-60 MPa. For dense sand it is 50-81 MPa. And for sand and gravel it is 100-200 MPa.
