Moment of Inertia

(OP)
I am used to having the momnet of ineria of rotating parts defined as wr2. recently I came across some data where it was expessed as GD2.

Can someone please explain.

RE: Moment of Inertia

wr2 is all I've heard of to.  Maybe its metric?  Let's hope some answer's your question.

GD2 = 4 * WR2
