A non-isotropic solid metal cube has coefficients of linear expansion as ` 5 xx 10^(–5) //^(@)C` along the x-axis and` 5 xx 10^(–6)//""^(@)C `along the y and the z-axis. If coefficient of volume expansion of the solid is `C xx 10^(–6) //""^(@)C` then the value of C is

Text Solution

Verified by Experts

The correct Answer is:
105
`gamma = alpha_x + alpha_y + alpha_z = 5 xx 10^(-4) + 5 xx 10^(-4) + 5 xx 10^(-5)`
`105 xx 10^(-5)//""^@C`.
