A steel I-beam is suppose to be used as a beam, however, it was found out that the cross section cannot resist the demand. Hence, a steel C-section is added at the top to increase the capacity against flexure as shown. I' 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!
