GATE CE 2007

MCQ (Single Correct Answer)

-0.3

For an isotropic material, the relationship between the young’s modulus (E), shear modulus (G) and Poisson’s ratio (μ) is given by

$$G\;=\;\frac E{\left[(1+\mu)\right]}$$

$$G\;=\;\frac E{\left[2(1+\mu)\right]}$$

$$G\;=\;\frac E{\left[(1+2\mu)\right]}$$

$$G\;=\;\frac E{\left[2(1+2\mu)\right]}$$

GATE CE 2002

MCQ (Single Correct Answer)

-0.3

The shear modulus (G), modulus of elasticity (E) and the Poisson's ratio ($$\mu$$) of a material are related as

$$G\;=\;\frac E{\left[2(1+\mu)\right]}$$

$$E\;=\;\frac G{\left[2(1+\mu)\right]}$$

$$G\;=\;\frac E{\left[2(1-\mu)\right]}$$

$$G\;=\;\frac E{\left[2(\mu - 1)\right]}$$
