Plane at which max normal stress & minimum normal stress present is called as principal plane. So, maximum principal stress is same as the maximum normal stress.

The resultant tensile stress is (1200+600)/2 =900 MPA shear stress =400 Mpa using maximum normal stress theory 1/2(900+ 900^2+4 * 400^2) = 1400Mpa.
