Question

For a given elastic material, the Elastic Modulus E is 210 GPa and its Poisson's Ratio is 0.27. What is the approximate value of its Modulus of Rigidity?

• A. 105 GPa
• B. 83 GPa
• C. 159 GPa
• D. 165 GPa

Answer 1

The correct option is B 83 GPa

As we know that,
$G=\frac{E}{2(1+\mu )}=\frac{210}{2(1+0.27)}=82.67GPa$
