Centre Of Gravity

[bill barlow]

where is the cog of a polo mint??

[EDDIE51]

A polo mint is a uniform ring.
The center of mass ,which is the correct name for center of gravity, is in the exact center of the hole! Yes, even though there is no actual Mass there.

Is that the whole truth, Old_Geezer?

To be pedantic, the embossed writing on a polo mint means that its COG will be slightly above mid height and displaced slightly from the exact centre.

. . . a lick off centre then.

To be pedantic (Part 2)

If the height of the polo mint is defined by the upper face of the embossed writing, its COG will be slightly BELOW mid height.

Since the embossed writing is diametrically symmetrical in the circular plane, there is no displacement from the exact centre.
