A small point in revolutionary mechanics (3)
I believe the answer is:
cog
This clue might be a double definition.
'a small point' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'revolutionary mechanics' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'in' is the link.
Can you help me to learn more?
(Other definitions for cog that I've seen before include "Projection on a toothed wheel" , "Tooth on the rim of gear wheel" , "Tooth on gearwheel" , "Machine wheel" , "bar" .)
