Principal Stresses - hoop and radial stress?

[BrianE22]

I'm learning Solidworks FEA. I have a disk for which I'm applying a centrifugal load. I'm looking for the tangential (hoop) stress and the radial stress to compare to the standard equations. I believe that would be Principal Stresses?

Never mind, I found some stuff on the web that shows how to get plots of radial and hoop stresses.
