The linear expansivity, \(\alpha\), and cubic expansivity, \(\gamma\), of a material are related by the equation?
- \(\gamma\)=a
-
\(\gamma\)=3\(\alpha\)
- \(\gamma\)=2a
- \(\gamma\)=\(\frac{1}{3} \alpha \)
The correct answer is: B
Explanation
cubic and linear expansivity are related by this equation. γ=3α.
