The coefficient of linear expansion of an inhomogeneous rod changes linearly from \( \alpha_{1} \) to \( \alpha_{2} \) from one end to the other
\( \mathrm{P} \) end of the rod. The effective coefficient of linear expansion of

W rod is :
(A) \( \alpha_{1}+\alpha_{2} \)
(B) \( \frac{\alpha_{1}+\alpha_{2}}{2} \)
(C) \( \sqrt{\alpha_{1} \alpha_{2}} \)
(D) \( \alpha_{1}-\alpha_{2} \)
