Moment of Inertia for Areas. We want to find the moment of inertia, I y of the given area, which is rotating around the y-axis. Each "typical" rectangle indicated has width dx and height y 2 − y 1, so its area is (y 2 − y 1)dx.. If k is the mass per unit area, then each typical rectangle has mass k(y 2 − y 1)dx.. The moment of inertia for each typical rectangle is [k(y 2 − y 1)dx] x 2 ...The first moment about the y-axis is the double integral over the region R forming the 2-D plate of the distance from the axis multiplied by the density.
