Transcribed Image Text:**Problem 10.2: Determine the moment of inertia of the beam cross-section about the centroidal x-axis.**
**Diagram Explanation:**
- The diagram illustrates the cross-section of an I-beam.
- The I-beam is symmetric, comprising three main sections: a top flange, a web, and a bottom flange.
- **Top Flange:** Width is 160 mm (80 mm on each side from the centerline), and height is 20 mm.
- **Web:** Width is 20 mm, and height is 240 mm (120 mm above and below the centerline).
- **Bottom Flange:** Dimensions are identical to the top flange: 160 mm wide and 20 mm high.
- The central axis (x-axis) is indicated horizontally through the beam's center, while the y-axis is vertical.
- Dimensions are clearly marked by dashed lines with arrows demonstrating the measurements of each section of the I-beam.
This setup is to assist in calculating the moment of inertia, focusing on understanding the geometry concerning the centroidal x-axis.
