Sectorial moment of inertia

The sectorial moment of inertia is defined as (refer to page cross-section characteristics for notation):

$I_{\omega }=\int _{A}{\omega }^{2}\;dA\;\;(mm^{6})$

Other Designations

The following designations are sometimes also used for sectorial moment of inertia:

• warping constant, $Cw$
