Question: The principal strains at a point are given by [ varepsilon_{1}=800 times 10^{-6}, varepsilon_{2}=-600 times 10^{-6}, varepsilon_{3}=400 times 10^{-6} ] If (v=0.25) and (mathrm{E}=200 mathrm{GPa}),

The principal strains at a point are given by

\[ \varepsilon_{1}=800 \times 10^{-6}, \varepsilon_{2}=-600 \times 10^{-6}, \varepsilon_{3}=400 \times 10^{-6} \]

If \(v=0.25\) and \(\mathrm{E}=200 \mathrm{GPa}\), calculate the principal stresses.
