Video for Polar moment of inertia for a rectangle section.
How do we get the expression for the Polar moment of inertia for a rectangle? A video also illustrates another way to find the product of inertia Ixy at the Cg for a rectangle.
The Timestamps for the video are shown.
- 0:00 – Use an area (dx*dy) to get the Ixy for the rectangle as a third proof.
