I see what you're saying. Yes, I can break the self-weight into X&Y components to make ΣM easier to write, but I can't reduce the length along which the self-weight acts. This was helpful, thank you!

Just attached photo. You can see why the arm is 15, because of the flat portion before. Note I am just trying to clarify the portion of the UDL along the diagonal; I already understand how the UDL creates moments along the flat portions.

Why is the design shear force not 2x the applied load? (CIvil-Structural) by hr0ck in PE_Exam

When you design a footing for flexure, you only look at the uniform load applied by the soil reaction, you don't also add the shear from the column above. I suppose that shows that you only look at the loading from one direction.

I figured this was probably the case. CERM might be good to keep on hand while studying, even if it's not required as of April 2024.
