Video for Ix for a right-angle triangle case 1.
This video illustrates how to calculate Ix for 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 rectangular strip about the X-axis. The vertical strip is treated as the sum of the inertia of a vertical rectangular strip about the X-axis.
