Repeat problem 18 for the stepped bar shown in the figure.

Data From Problem 18:

A stepped bar is clamped at both ends. A force of \(F=10,000 \mathrm{~N}\) is applied as shown in the figure. Areas of cross sections of the two portions of the bar are \(1 \times 10^{-4} \mathrm{~m}^{2}\) and \(2 \times 10^{-4}\) \(\mathrm{m}^{2}\), respectively. Young's modulus \(=10 \mathrm{GPa}\). Use three bar elements to solve the problem.
