>>> The "oarlock" analogy is just senseless, no one ever suggested that in rotational mechanics the hands remain stationary. <<<

Hi Daniel

You are correct. No one (including myself) ever suggested that in rotational mechanics the hands remain stationary. I would point out that an oarlock on a boat being rowed is not necessarily stationary either. When we say something is stationary (or moving), we should also say ‘in reference to what’. – A seat on a merry-go-round may be moving to a bystander, but stationary to the person setting in it. The same is true with the hands is the swing. They may be moving fast to a stationary camera, but fairly still in reference with the rotating body.

Maybe after further clarification of our views, we may not disagree as much as you think.
