The Diagnostic Test Centre/Blood Collection Lab will take samples of your blood and will send them to be tested. The samples will be tested to learn more about your condition and help guide discussion about your diagnosis and treatment. For general inquiries, please contact our 24-hour Call Centre at 416 340 LABS (5227) or 1 866 865 LABS.
to derive the moment of inertia of a solid sphere of uniform density and radius R. [tex] dI = r_{\perp}^{2} dm = r_{\perp}^{2} \rho dV [/tex] â. where [itex] r_{\perp} [/itex] is the perpendicular distance to a point at r from the axis of rotation. Therefore, [itex] r_{\perp} = |\mathbf{r}|\sin{\theta} [/itex].
The mechanics of the Earthâs rotation avout its axis introduces a quantity called the moment of inertia, which is the rotational mechanical analogue of mass. The moment of inertia of a point mass, m, rotating at a distance, r, about an axis is mr 2.
