PROBLEM 1 The general form for the three-dimensional stress field is given by $\begin{bmatrix} \sigma_{xx} & \sigma_{xy} & \sigma_{xz} \\ \sigma_{yx} & \sigma_{yy} & \sigma_{yz} \\ \sigma_{zx} & \sigma_{zy} & \sigma_{zz} \end{bmatrix}$ We would like to calculate principle stresses. The principle stresses are eigenvalues of the the three-dimensional stress field. Calculate the principle stresses for $\begin{bmatrix} 10 & 14 & 25 \\ 14 & 7 & 15 \\ 25 & 15 & 16 \end{bmatrix}$
