Gears
Thanks
Mechanical
The
mechanism above has four gears.
The red
numbers inside each gear (90, 30, 10, 5) represent the number of teeth
in each gear.
In
the big gear (90
teeth), a hand turns with the gear.
The
hand points to 12.
Question:
Once
the gear with 30
teeth has made one
complete clockwise
revolution, where will the hand point?
