Consider a fixed-fixed steel bar with the length (=0.1 mathrm{~m}) and the cross-sectional area (=4 times 10^{-4}

Question:

Consider a fixed-fixed steel bar with the length $=0.1 \mathrm{~m}$ and the cross-sectional area $=4 \times 10^{-4} \mathrm{~m}^{2}$. Using the finite element method, determine the first three natural frequencies and compare them to the theoretical values.
