Question

Two wires of same length and radius are joined end to end and loaded. The Young's moduli of the material of the two wires are $Y_1$ and $Y_2$. The combination behaves as a single wire then its Young's modulus is :

Select the correct option:

$\frac{2 Y_1 Y_2}{3\left(Y_1+Y_2\right)}$

$Y=\frac{2 Y_1 Y_2}{Y_1+Y_2}$

$Y=\frac{Y_1 Y_2}{2\left(Y_1+Y_2\right)}$

$Y=\frac{Y_1 Y_2}{Y_1+Y_2}$
