# In a triaxial stress system, the six components of the stress point are given below.

${\sigma}_{x}=6MN/{m}^{2}{\tau}_{xy}={\tau}_{yx}=1MN/{m}^{2}$

${\sigma}_{y}=5MN/{m}^{2}{\tau}_{yz}={\tau}_{zy}=3MN/{m}^{2}$

${\sigma}_{z}=4MN/{m}^{2}{\tau}_{zx}={\tau}_{xz}=2MN/{m}^{2}$

Find the magnitude of three principal stresses.
