Second Polar Moment of Area
\(I_p = \int r^2_Q dA\), where \(r_Q\) is the radial distance from a \(Q-axis\) and \(A\) is area.
The moment of inertia, also called mass moment of inertia, rotational inertia, polar moment of inertia of mass, or the angular mass is a property of a distribution of mass in space that measures its resistance to rotational acceleration about an axis.
