Center of gravity - conflicting result

[Femme_physics]

Definitely, definitely, definitely the most annoying exercise to date.

Thanks for leading me through that. Give me a moment :)

You took the half circle offset from the left side of the circle, instead of from the center of the circle.
That would be correct in your original choice of the coordinates (with the center of the circle as the origin), but with the origin at the leftmost point of the object, you need to compensate. ;)

So my length for the half circle wire is 20 minus 2x20/pi? I recall trying that but still not getting the right result

Try again?

Aww, so this is not a neverending story?

Pity!
