The first method used to get the product of inertia Ixy for a Rectangle. ![]() We will estimate the horizontal distance as X to y CG and y to the CG. This is a part of the video with a closed caption in English. But this time, our strip will be small with width =dx and height =dy. Again, we have our rectangle with base b and height h, and we have external two axes x and y at the left edge left corner of the rectangle, and we have x CG and y CG. This is a link to the first video via u-tube.Ī third method is presented in the following video to estimate the Ixy g as a third proof. This is a part of the video with a closed caption in English. for example, A1 is the area the width = (b/2) the height is (h/2). ![]() We divide this rectangle into 4 areas, namely A1, A2, A3, A4, and for each area, we are going to locate the CG of every area. Then we come to the CG and we draw another two axes, which are X’ and y’. We draw a rectangle for which the Base is b and the height is h, and we introduce the external two axes X and Y. We want to prove that the product moment of inertia for a rectangular section =0. In Unit number 5, we’re going to talk about the product moment of inertia for a rectangular section at the CG. Product Of Inertia Ixy for a Rectangle at the CG video. Product Of Inertia Ixy for a Rectangle at the CG.
