This is an added effort in response to your question after your latest update.
In the situation above, if a < d (beam depth), practically we can replace the uniform load with a concentrated load, and say it is justified by the Saint-Venant Principle.
However, it will run into problems with the actual behaviors from the beam theory if we proceed to check ...

I would like to add something to the already existing answer here.
Yes, it would be considered as an application of Saint Venant's principle. Since the law just mentions about replacing a point force with an equivalent distributed force over the area and vice versa, it can be an externally applied force or it can be a reaction force, so it doesn't matter.

Yes it is correct. This is not a dire t answer but can shed some light on the question.
We do a lot of simlar substitution of point load for distributed loads and vice versa.
we do the same exchenge between point loads to one moment e g, in bolted hangar roof beam to column or bolted brackets supperting a beam.
in the elbow bolt group we find the CG of the ...

Yes, I think you can say so if you reverse its concept exactly the way it is concerned. The explanation (of the concept) below is quite straightforward and precise:
Saint-Venant's Principle simply states that the stress measured at any point on an axially loaded cross section is uniform given that the measured location is far enough away from the point of ...
