Yep, Stiction Friction. Learned about it back in early 60's when we had to
send a "dither" signals to gyros to overcome Stiction Friction and improve
accuracy (missile program). What's the old saying, things at rest tend to
stay at rest and things in motion like to keep moving or something like that
;-)

Roger,
I have an addition we learned from Rick, N6RK in his earlier post.
STICTION Another term for static friction
(I thought Rick was being humorous, but I looked it up and it is defined
as :
"Stiction is the static friction that needs to be overcome to enable
relative motion of stationary objects in contact." )
Rick, I will never doubt your stuff again hihihihi
