Product Second Moment of Area Ixy - Help!
hi, ive been tryign to work out the stress at a point for a T X-section area of a beam. However, the T-shape IS NOT symmetrical.
The general formula is Ixy = Ixy g + AXY (X = X bar and Y = Y bar)
I have X bar and Y bar and Area of course too.
i Dont know how to calculate the first term of this equation which is the Ixy g bit.
Could someone please help. this is driving me nuts.

What does "g" represent? I assume Ixy g meant the centrifugal moment of area through the centroid axis? I don't know why it wouldn't work. Apply Steiner's rule (the one you wrote down) a few times, and you should be able to calculate it.
