Second Moment of Area Example 4 (I beam)

The video tutorial demonstrates how to calculate the second moment of area for an I-beam about the X-axis at the centroid. The instructor advises against using calculus due to the complexity of the shape and instead recommends using formulas for rectangles and the parallel axis theorem. The I-beam is deconstructed into three rectangles, and the second moment of area is calculated for each, then summed to find the total. The final result is presented in millimeters to the fourth power.
