Question

If the Young's modulus 'E' is equal to the bulk modulus 'K', then what is the value of the Poisson's ratio?

• A. $1/4$
• B. $1/2$
• C. $1/3$
• D. $3/4$

Answer 1

The correct option is C $1/3$

$K=\frac{E}{3(1-2\mu )}$
$\because K=E$
$\therefore (1-2\mu )=\frac{1}{3}$
$\Rightarrow \mu =\frac{1}{3}$
