Repeat problem 10 with the initial design of (b_{1}=2 times 10^{-4} mathrm{~m}^{2}) and (b_{2}=1 times 10^{-4} mathrm{~m}^{2}).
Question:
Repeat problem 10 with the initial design of \(b_{1}=2 \times 10^{-4} \mathrm{~m}^{2}\) and \(b_{2}=1 \times 10^{-4} \mathrm{~m}^{2}\). Discuss the results with that of problem 10 .
Data From Problem 10:
Consider a twobar structure in the figure with Young's modulus \(E=100 \mathrm{GPa}\), yield stress \(\sigma_{Y}=250 \mathrm{MPa}\), and \(F=10,000 \mathrm{~N}\). Design variables are \(b_{1}=\) area of section \(\mathrm{AB}\) and \(b_{2}=\) area of section BC. Starting from the initial design of \(b_{1}=1 \times 10^{-4} \mathrm{~m}^{2}\) and \(b_{2}=2 \times 10^{-4} \mathrm{~m}^{2}\), perform fully stressed design to obtain minimum cross-sectional areas.
