NEET Questions / Physics / Mechanical Properties Of Solids / Poisson'S Ratio
Poisson's ratio is defined as the ratio of:
Longitudinal strain to lateral strain
Lateral stress to longitudinal stress
Longitudinal stress to lateral stress
Lateral strain to longitudinal strain
A material is stretched longitudinally. If its Poisson's ratio is 0.5, what happens to its volume?
Increases
Decreases
Remains constant
Becomes zero
Poisson's ratio is a dimensionless quantity. This implies that:
It has units of length
It has units of force
It is a ratio of two like quantities
It is always a negative number
Which of the following is the theoretical limit for Poisson's ratio of any material?
-1
0
0.5
1
If the value of Poisson's ratio is zero, it means that:
There is no longitudinal strain when lateral stress is applied.
There is no lateral strain when longitudinal stress is applied.
Longitudinal and lateral strains are equal.
Longitudinal strain is zero.
The Poisson's ratio for most metals lies between:
0 and 0.1
0.1 and 0.2
0.2 and 0.3
0.25 and 0.35
