Dudely.. he said turning by banking only.. he said nothing of "inside
rudder"
at least not the way I read it

I admit the question is a little vague to say the least. I think I might
have got caught up in that "turn"(yaw) thing and read it to mean
complimentary yaw producing turn as a secondary effect.
I read it as asking several things that were not exactly correct in
premise to begin with!

For example;
"Unlike the elevators and rudder that change an aircraft's pitch and
yaw with no other secondary effect,"

I have a bit of a problem with this premise before even getting into the
"question"
:-)
Then we have this;
"why does the banking of wings by
the use of ailerons not just roll an aircraft but also produces a turn
(yaw)? "

I read his context as aileron being used and producing turn which in the
turn (inside context) would be complimentary yaw.....which of course
wouldn't be the secondary effect of using aileron to begin
with.........are you following this........cause I'm getting lost!!!
:-)))
The parenthesis (yaw) opens up a whole deck of cards since banking the
airplane with just aileron would produce adverse yaw; not complimentary
yaw, and it will also as a secondary effect after adverse yaw had
stabilized, produce turn if not held back with anti turn controls. It's
puzzling the way he worded it really.
I'm not sure really what he was asking at this point!! :-)

Anyway, the answer for uncoordinated turn entry using various isolated
control inputs would be if aileron alone....adverse yaw followed by turn
after stabilization and vector split;
and inside rudder alone; turn as bank is introduced as the secondary and
the lift vector splits.
You are completely right of course about dihedral effect!
Anyway....I think I'll leave this for you guys to play with. I'm going
to bed!!
:-)
Have a good one,
