mass polar moment of inertia

[cadman777]

Can anybody tell me where or how to get the mass polar moment of inertia of an assembly w/referenct to an axis about which it rotates?

I also need the radius of gyration, so I can do some power calcs on this assembly for selecting a drive unit.

Inventor has a wonderful collection of solids that it should be able to use to generate the Jm & k, if only I can find the command.

Thanx ...

HI!

It is what youre try to find?? it's in the assembly's iProperties.

Did you find this reply helpful ? If so, use the    Accept as Solution or Kudos - Thank you!

Thanx CC.

I want to know what each of those numbers mean.

There's a lot of confusion about them, and the help file is useless in explaining them.

I think I made myself clear.

If someone knows which number under which button is the mass polar moment of inertia and where I can get the mass radius of gyration, please be so kind as to show me.

Thanx ...
