Chapter 10, Problem 10-33(choose chapter or problem)
The principal strains at a point on the aluminum fuselage of a jet aircraft are \(\epsilon_{1}=780\left(10^{-6}\right)\) and \(\epsilon_{2}=400\left(10^{-6}\right)\). Determine the associated principal stresses at the point in the same plane. \(E_{\mathrm{al}}=10\left(10^{3}\right) \mathrm{ksi}, \nu_{\mathrm{al}}=0.33\). Hint: See Prob. 10–30.
