Which of the following statements is correct regarding poissen's ratio?

Options

A. It is the ratio of the longitudinal strain to the lateral strain.
B. Its value is independent of the nature of the material.
C. It is unitless and dimensionless quantity.
D. The practical value of poisson's ratio lies between 0 and 1.

Answer

C

Explanation

The ratio of the lateral strain to longitudinal strain is called poisson's ratio.
Hence optiong (a) is an incorrect statement.
Its value depends only on the nature of the material. Hence option (b) is an incorrect statement.
It is the ratio of two like physical quantities.
Therefore, it is unitless and dimensionless quantity.
Hence, option (c ) is a correct statement. The practical value of Poisson's ratio lies between 0 and 0.5. Hence option (d), is an incorrect statement
