V. In the limiting case in which F conicides with A, the 
loads should cover A C as completely as possible, the heaviest 
loads being brought as near C as possible; these conditions 
being satisfied as nearly as possible while the general condition 
is exactly satisfied. In this case the general condition may be 
conveniently used in the form 
Q = ~ 
n 3 
In deciding which is the probable position for greatest stress, no 
regard need be paid to loads on D B, since they do not affect the 
stress under consideration.
