The principal strains in a plane are (epsilon_{1}=630left(10^{-6} ight)) and (epsilon_{2}=350left(10^{-6} ight)). Determine the associated principal stresses

The principal strains in a plane are \(\epsilon_{1}=630\left(10^{-6}\right)\) and \(\epsilon_{2}=350\left(10^{-6}\right)\). Determine the associated principal stresses at the point in the same plane. \(E_{\mathrm{al}}=10\left(10^{3}\right) \mathrm{ksi}\) and \(u_{\mathrm{al}}=0.33\).
