Talking about memory aids - I dredged my way back through this thread
to 
http://www.google.co.uk/groups?as_umsgid=cvbfgc%24569%241@nnrp.gol.com
which was where Ron first implied that KG was incorrect in his knowledge of
the forces involved in sitting on a chair.

Ron - You're a physics/mechanics ignoramus.
Jeff - You're arguing with someone who is a physics/mechanics ignoramus
and is apparently immune to education even when applied with a clue-by-four
to the back of the head.

I shall now leave this thread in the hope that it dies a swift and painful death.
