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].
Moment of inertia can be measured using a simple pendulum, because it is the resistance to the rotation caused by gravity. Mathematically, the moment of inertia of the pendulum is the ratio of the torque due to gravity about the pivot of a pendulum to its angular acceleration about that pivot point.
