### Moment of Inertia and Properties of Plane Areas

The moment of inertia of an area with respect to any given axis is equal to the moment of inertia with respect to the centroidal axis plus the product of the area and the square of the distance between the 2 axes. The parallel axis theorem is used to determine the moment of inertia of composite sections. Moment of Inertia of a Rectangular Cross SectionI also know that more generically, the moment of inertia is given by the integer of an area times the square of the distance from its centroid to the axis. So lets say I have a rectangular section with a height of 200 mm and a width of 20 mm.
