UNDERFIRE...
what if the floor load limitation is 500 kg/m2
wouldnt we be exxceeding the limit ??
Structurally, not to overthink this, at all...
Structurally, if one uses distributed load method of calculation of kg/m2, you use m2, not parts of M2 (hope that makes sense)
There is the entire surface area of the load on the deck. The area of the load is 1.5x3 or 4.5 m2. 2000/4.5= 444 kg/m2
If you used 667 kg/m2, that 4.5m2 surface area taken by the load would equate to a little over a 3000kg load (50% more)
Thats no way to load an aircraft!
That is why, if you do not have to, you make the spreaders the same size as the load, only make them larger if you are over the psm loading
you are referring to the load on the deck, ie the area in contact with the floor right ???
