There is a common misconception as to how dihedral works that talks about how the difference in vertical components of lift. This video addresses this misconception well at 1:47

Im having an incredibly difficult time explaining to people why the difference in vertical lift doesn't affect net torque and roll the plane back. Anyone have any suggestions on possible explanations? For students they see that one wing is generating for vertical lift than the other, so they assume that because of that, the lowered wing will roll the airplane upright again. I'm not confident on a way to explain why that isn't the case.
