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 _____________

Correct answer

0

Step-by-step solution

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