Question:

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.
