Busser is right. In a steady turn, the Angle of attack is the same.
Coordinated, not steady. One can perform steady slipping or skidding turn where it is not the same.
The lift vector is perpendicular to the wing.
In coordinated turn. Not so if performing e.g. forward slip...
...which you absolutely had to perform a couple of times with your experience.
To keep most aircraft in a turn you have to hold a small amount of aileron - if you centralise the yoke the aircraft will tend to roll back to wings level.
Interesting... I have always flown exotic designs that don't display this behaviour, such as Cessna 172.
I have no idea what lightenings diagram is showing.
I do. It shows B737 series 300 or higher in left bank and slipping to illustrate AoA difference when slipping the dihedralled wing. I've seen it first in my ATPL papers.
I think they want to know if, in a balanced turn, the angle of attack is the same for both wings.
No. He asked:
Anyone out there can explain to me why the dihedral design causes the the lower wing to have a larger angle of attack than the higher one during a bank?
...which is unexplainable as it's not bank but slip what causes dihedral effect to work.
