Sx, Sy, Sxy are in units of (say in English) of ksi, so adding terms requires the same units. Mx, My, Mxy are in units of kip-in/in, and according to the help page AD.V8i.3.2 Enhanced Plate Stress Results, S, section modulus, has units of (in^2/in). When the math is done out, the units can't be added, or make sense. Can someone please clarify? thanks!
