Answer:

E=2.0*10^{11}N/m^{2}

Explanation:

<u>Relation between stress and Force:</u>

\sigma=\frac{F}{A}=\frac{F}{\pi*d^{2}/4}

<u>Relation between stress and strain:</u>

Young's modulus is defined by the ratio of longitudinal stress σ , to the longitudinal strain ε:

E=\frac{\sigma}{\epsilon}

\epsilon=\frac{\Delta l}{l}

So:

E=\frac{F*l}{\pi*d^{2}/4*\Delta l}=\frac{50*10^{6}*3}{\pi*(0.4^{2}/4)*5.967*10^{-3}}=2*10^{11}N/m^2
