Hi everyone.
I know this subject has come up previously but not to the thorough extent that answers the problem correctly.
Say we have an I beam and want to find the Second Moment of Area. We can easily find the Centre of Inertia's y coordinate (relative to a sex of axis) seeing as almost every time the measurements refer to the bottom of the I beam as y = 0. That is the simple part.
But say that the I beams' dimensions of the two horizontal rectangles are not of the same length. How can we possibly find the Center of Inertia's x coordinate if its two horizontal rectangular dimensions are not dimensioned relative to an x-axis?
