Question

 The equation of lateral strain is
​

Answer 1

Answer:

Lateral strain is the strain is the strain in the diameter of the cylinder. However, the lateral strain is not uniform in this case. Poisson's ratio for this cylinder will be lateral strainlinear strain=D′−DDL′−LL. Note: The value of strain can be negative as well as positive.

Answer 2

Answer :-

In mechanics, Poisson's ratio is the negative of the ratio of transverse strain to lateral or axial strain.

• Symbol Greek letter - 'nu',ν
• Formula Poisson's ratio = – Lateral strain / Longitudinal strain.
• Range - 1.0 to +0.5
• Units - Unitless quantity
