For the I - beam:

  • Flange width is 329 mm.
  • Flange thickness is 24 mm.
  • Web height is 289 mm.
  • Web thickness is 38 mm.

For the C-section:

  • Flange width is 52 mm.
  • Flange thickness is 34 mm.
  • Web height is 489 mm.
  • Web thickness is 28 mm.

Would you kindly help me find the centroidal moment of inertia for both the X and Y axes based on these dimensions? Thank you!
