Question

The formula relating youngs modulus (Y), rigidity modulus (n) and Poisson's ratio ($\sigma$) is

• A. $Y=2n(1-\sigma )$
• B. $Y=2n(1+\sigma )$
• C. $Y=n(1-2\sigma )$
• D. $Y=n(1+2\sigma )$

Answer 1

The correct option is B $Y=2n(1+\sigma )$

Young's modulus and rigidity modulus can be related to poisson's ratio as $Y=2n(1+\sigma )$
The correct option is (b)
