A non-isotropic solid metal cube has coefficients of linear expansion as: 5 × 10 − 5 / o C along the x-axis and 5 × 10 − 6 / o C along the y and the z-axis. If the coefficient of volume expansion of the solid is C × 10 − 6 / o C then the value of C is _____________

V = 2 α 2 + α 1 = 10 × 10 - 6 + 5 × 10 - 5 = 60 × 10 − 6 / o C

A non-isotropic solid metal cube has coefficients of linear expansion as: $5 \times 10^{- 5} /^{o} C$ along the x-axis and $5 \times 10^{- 6} /^{o} C$ along the y and the z-axis. If the coefficient of volume expansion of the solid is $C \times 10^{- 6} /^{o} C$ then the value of $C$ is _____________

Answer:

60.00

Solution:

$V = 2 α_{2} + α_{1}$
$= 10 \times 10^{- 6} + 5 \times 10^{- 5}$
$= 60 \times 10^{- 6} /^{o} C$
