Video for Practice Problem 1: Moment of Inertia.
In Practice Problem 1, the video shows how to find the Moments of inertia Ix and Iy, the radii of gyration Kx and Ky about the x- and y-axes, and the radius of gyration Ky about the y-axis for a given rectangle. The rectangle is 40cmx 60 cm.
The video timestamps are shown.
- 0:00 – Practice problem#1: find Ix, Kx, Iy, and Ky for a given rectangular section.
- 02:58 – The steps to find the value of Ix and kx.
- 03:49 – The steps to find the value of Iy and ky.
