Engineering Mechanics - Dynamics Chapter 21 I zx ω x I zy y I zz I () z + 0 = Solution for nontrivial x , y , and z requires I xx I Iyx I zx I xy I yy I I zy I xz I yz I zz I 0 = Expanding the determinant produces the required equation QED Problem 21-22 Show that if the angular momentum of a body is determined with respect to an arbitrary point A , then H A can be expressed by Eq. 21-9. This requires substituting ρ A = ρ G + ρ GA into Eq. 21-6 and expanding, noting that ∫ρ G d m = 0 by definition of the mass center and v G = v A + ω × ρ GA . Solution:
