I don't get this. Why not push when removing?

For the same reason you lift your feet when you walk.


I don't get that either. A screw is a helical ramp, more or less. You
turn it to go in and come out. The farther the screw is in, the more
friction/resistance there is in both directions. Most often, I find it
necessary to push on a screw when removing it, at least until it's a
good deal out.

What am I missing?
