I saw this question today, on whether hydrostatic loads are "dead" or live". Very heavily related is this previous question on whether a moving load (that is always somewhere) is "dead" or "live".
I expected to be able to close the newer question as a duplicate, because the majority of an answer needs to discuss why we talk about dead loads as opposed to live loads. But, because the actual specific of the question is different, it's not a duplicate.
I see three possible ways forward:
Leave both questions as they are, separate but related
Create a new question on "what is a dead load vs a live load", and make both existing questions duplicates of that
Create a new question on "what is a dead load vs a live load", make both existing questions related to that; allowing the answers in the existing questions to skip the generic dead vs live arugment, and only cover the specifics
