Hope nobody minds if I don't buy any of the answers .
If a wing has a round shape like a barrel then it won't stall at any angle irrespective of what the chord (dia) may be
(Also it won't lift worth a darn)
If we take a big hammer and start pounding the barrel to change thickness to chord ratio
the angle at which it stalls will progressively change
once we have pounded the barrel flat - it will be great at lift but super critical at operating angles
There you have have it
In my own book of airfoils , there are two basic shapes:
round and flat
all the rest are simply compromises which are hopefully matched to a specific requirement.
