In the end, it is the position of the body in space that is important, not its rotation, nor the exact position of any point on it

Then, you can just ignore the circle and apply the forces directly in the point A.

If the only thing that matters to you is the final position (it is not clear from your post), then you can avoid all the calculations. The stable position happens when AB is aligned with F. Though in the absence of any friction, what you have there is a pendulum.

If the force changes with the position, the logic remains the same, though you will have to find the point A where F(A) and AB align.
