Video for Ix for a right-angle triangle case 1.
A video illustrates how we calculate the value of Ix for a right-angle case 1, where the opposite side is on the left. We use two methods: a horizontal strip and a vertical strip.
The horizontal strip is treated as the sum of the inertia of a horizontal rectangle strip about the X-axis. The vertical strip is treated as the sum of the inertia of a vertical rectangle strip about the X-axis.
You can refer to post-7 for more illustrations and to download the PDF data for more details
