If you look at my initial post, I was replying to someone who wanted to know ‘if it was friction’ which was causing the difficulties in moving the trim wheel under higher aerodynamic loads. Yes, I could have given a more sophisticated example but there wouldn’t have been much point.
And it is not at all misleading. My example was of a screw system where a predominantly axial load gradually shifts to a lateral load as the force applied deviates from the axial. This is exactly what happens in the real jack screw mechanism regardless of how it is mounted.
