Cap 56,
Unable to link to Fred's reference at the moment ... perhaps that will lift the veil of confusion from my eyes in due course. And, of course, lots of little piccies are always a GOOD THING when trying to work out what's what .. unless, of course, you are Stephen Hawking and can do it all in your head .. what an incredible mind that man must have ..
Presuming your "on" is intended to be "no", that's fine for a simple torque ... no contrary view from me .... but an aeroplane in flight has a myriad of forces so the simple couple thing is a not-very-useful artefact of imagination, I suggest ? .. and, in any case, how does that relate to the suggestion in your previous post ?
