A non-isotropic solid metal cube has coefficients of linear expansion as :
5 $\times$ 10-5/oC along the x-axis and 5 $\times$ 10-6/oC along the y and the z-axis. If the coefficient of volume expansion of the solid is C $\times$ 10-6/oC then the value of C is
Answer (integer)
60
Solution
$\gamma$ = $\alpha$<sub>x</sub> + $\alpha$<sub>y</sub> + $\alpha$<sub>z</sub>
<br><br>$\Rightarrow$ C $\times$ 10<sup>–6</sup> = 5 × 10<sup>–5</sup> + 5 × 10<sup>–6</sup> + 5 × 10<sup>–6</sup>
<br><br>$\Rightarrow$ C $\times$ 10<sup>–6</sup> = 50 × 10<sup>–6</sup> + 10 × 10<sup>–6</sup>
<br><br>$\Rightarrow$ C = 60
