Eigenvalues: σ1=σ2=5, σ3=-1

It must be simple, but I don't know how to determine the normal vector of that plane analytically.

I know σ=0.

**t**=T

**n**=

**σ+τ=τ**

If normal stress σ equals zero, ¿the shear stress will be the maximum value of τ ((σ1-σ3)/2)?

Taking a look to Mohr's circle I think τ in that plane must be the intersection between the circunference and the τ axis, but that's not τmax.

I'm confused.
