Good afternoon.
Please tell me with the calculations in your table:
Calculating Ixx values for more complex shapes (using parallel axis theorem)

Please give an example.

I’m away from the PC so will give a brief explanation. For complex shapes you need to break it down into a series of standard shapes such as rectangles, calculate the Ixx for each shape, then multiply by the area of each shape and the square of its distance from the overall shape neutral axis and sum these values together.

Google parallel axis theorem for examples. I’ll post a better explanation another time.
