Which of the following is the correct expression that relates modulus of elasticity (E), shear modulus of elasticity (N) and Poisson's ratio (\(\frac{1}{m}\)) of a material?
1
\(\frac{E}{2}\) = N \((1 + \frac{1}{m})\)
2
\(\frac{E}{2}\) = N\((1 - \frac{1}{m})\)
3
\(\frac{E}{3}\) = N \((1 + \frac{1}{m})\)
4
\(\frac{2}{E}\) = N \((1 + \frac{1}{m})\)
