Hey guys, I am having some trouble understanding this problem.
The horizontal x-axis is drawn through the centroid C of the area shown, and it divides the area into two component areas A1 and A2. Determine the first moment of each component area with respect to the x axis.
[PLAIN]http://img826.imageshack.us/img826/982/111110090100.jpg I took the origin to be at the bottom center.
For my Ybar, I got 4.0833.
I'm kind of stuck on how to go about finding the first moments.Thanks!
