Hello, I will appreciate if someone can help me with the following problem:

I need to have the moments of inertia of the assembly shown on the picture. But as you can see the inertia axes are rotated to a certain degree and I need them to coincide the Origin axes without rotating the assembly, because its normal position will be as shown. Is it possible to be done and how?

Actuallu it is not even necessary the X inertia axis to coincide with the X origin axis, etc. All I need is Any of the inertia axes to coincide with any of the origin axes.

I hope I'll have this problem solved soon. Thank you in advance.
