Q62
What is the significance of Poisson�s ratio in rock mechanics?
A.
Measures rock color
B.
Indicates rock permeability
C.
Describes lateral strain behavior
AnswerD.
Defines joint roughness
Answer: Option C
Solution
Answer: Option C
Solution:
Poisson�s ratio is the ratio of lateral strain to axial strain in a material. It is a measure of how rock deforms in directions perpendicular to applied stress.
