Lets call
length of the inlined bar=L
Y of force = y
base of triangl= b
height of triangle=h
angle of bar= a
There will be a normal force $F*y/h*cos(a)$
and a horizontal force $F-F*y/h*cos(a)* \mu - N\mu $.
But the system will accelerate if
If $F_{ef}>N*\mu_{triangle}$
The triangle will topple if $F_{ef}*y>N*b/2 $

UPDATE (I think I misunderstood the constraints in my previous answer)
Assuming
the greyed out triangle beneath B is rigid and its resting on the horizontal plane with a coefficient of friction $\mu$
the beam is pinned on B and simply resting on A.
The force F is large enough, so that the triangle is about to move/rotate.
Then it depends on the coefficient ...

The compressive stress is, of course, a factor, but if we consider a simple brick wall, then this H calculation would not suffice since there is lateral stability to consider as well surely, any misalignment or lateral force e.g. crosswind would compromise height a lot I think.
