The second moment of area, or second area moment, or quadratic moment of area and also known as the area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. The second moment of area is typically denoted with either an See more For more complex areas, it is often easier to divide the area into a series of "simpler" shapes. The second moment of area for the entire shape is the sum of the second moment of areas of all of its parts about a common axis. This … See more See list of second moments of area for other shapes. Rectangle with centroid at the origin Consider a rectangle with base $${\displaystyle b}$$ and height $${\displaystyle h}$$ whose centroid is located at the origin.
