Determine the elongation of the rod in the figure below if it is under a tension of \( 4.5 \times 10^{3} \mathrm{~N} \). Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. \( \mathrm{cm} \) \[ \frac{F}{A}\left(\frac{L_{1}}{x_{1}}+\frac{L_{2}}{y_{2}}\right) \] Need Help? (i) \[ \begin{aligned} \frac{4.5 \times 10^{3}}{1.25 \times 10^{-5} \mathrm{~m}^{2}} & \left(\frac{1.3 \mathrm{~m}}{69 \times 10^{9} \mathrm{~N} / \mathrm{m}^{2}}+\frac{2.6 \mathrm{~m}}{117 \times 10^{9} \mathrm{~m}}\right. \\ & =(0.0173 \mathrm{~m})\left(\frac{100 \mathrm{~cm}}{1}\right) \end{aligned} \]
