SOM: Short Interview Question Answers on Poisson’s Ratio Q. What is POISSON’S RATIO? Symbol is μ (mu) or ν (nu) μ = lateral strain / linear strain =Negative (-) in nature (because lateral and linear strains are of opposite nature) μ <<1 because lateral strain is much less than linear strain. Lateral strain is the strain […]
