Mass Properties - Inertia
Mass Properties - Inertia
(OP)
I'm trying to use SW to help me confirm a calculation I've done by hand. I have an equilateral tetrahedron (4-sided solid, all sides equilateral triangles) and I'm trying to calculate its moment of inertia about one of its edges. I've put a coordinate system in the center of one of the edges on the base and selected it in the mass properties box. I assume that Ixx will be my moment of inertia along the edge as long as my x-direction is defined along that edge. Am I correct? What do Ixy, Ixz, Iyx, etc tell me?
Thanks,
Thanks,

One is mass moment of inertia and the other is geometrical moment of inertia.

You should be able to go to Section Properties next to Mass Properties and then select the face/plane that you want the properties for.

RamblinWreck06, hope my digression has answered some of your questions.
