Question
What is Poisson’s Ratio?
Answer
Poisson’s Ratio (σ)- In general, a deforming force in one direction can produce strains in other directions such as when wire is stretched, as described in figure given below: Poisson’s ratio is given by σ = -Transverse strain/Longitudinal strain ⇒ σ = – △ d/d/△L/L Theoretical value of σ varies from – 1 to 0.5.
