Perhaps I can't explain it well either, without pictures. But it's not all too complicated. With pencil and paper, I could explain to a high school student. If you've done college level mechanics, that's on me, or on the medium. Perhaps I need to make a video explaining this clearly, since people are running in circles around this and it's just not very hard.
