Find a college freshman text on "statics."  It's gonna be in there.  My
books are all buried in my move from Minneapolis to Dallas, so I con't find
it myself.  If your engineering school has a mechanical engineering
department, they should have a text book.  If worse comes to worst, and
introductory materials science (mechanical properties of materials) may
list the same information.

It's a fairly intuitive formula with a constant for correction to actual
values.  At worst, it will involve a moment of inertia for non-recantular
shapes.
