Question:

a. Show that the first moment of a body in space about any plane through the body’s center of mass is zero.image


b. To prove the Parallel Axis Theorem, place the body with its center of mass at the origin, with the line Lc.m. along the z-axis and the line L perpendicular to the xy-plane at the point (h, 0, 0). Let D be the region of space occupied by the body. Then, in the notation of the figure,image


Expand the integrand in this integral and complete the proof.
