Hello,
I'm looking for the center of mass and inertial matrix of an Arduino Uno. Right now the best method I could come up with is trying to approximate it in Solidworks but I'd prefer real world figures.
If anyone has any information or recommendations that would be much appreciated!
Use the good old manual method for CoG - a plumb line.
Hi,
CofG is relatively easy, the Moment of Inertia is more difficult I believe.
(Too long since I was taught.. :o )
What is your application that needs you to know these physical parameters?
There will not be any figures due to the fact that being open source there are many many different clones and hence physical component setups on the market.
Tom... 
It is also possible to experimentally determine the moment(s) of inertia.
