Area Moment of Inertia - Square Cross-Section with centroid at the origin

Description

The second moment of area, also known as moment of inertia of plane area, area moment of inertia, polar moment of area or second area moment, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. Area MoI for a filled rectangular area with a base width and height of “b” with respect to an axis horizontal passing through the center of the area parallel to the base is depended on the base of the square cross section.
