Question

If the Poisson's ratio for a material is 0.5, then the elastic modulus for the material is

• A. three times its shear modulus
• B. four times its shear modulus
• C. equal to its shear modulus
• D. not determinable

Answer 1

The correct option is A three times its shear modulus

Elastic modulus $=E$
Shear modulus $=G$
$E=2G(1+\mu )$
Given $\mu =0.5,E=2\times 1.5\times G$
$E=3G$
