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 (for an axis that lies in the plane of the area) or with a (for an axis perpendicular to the plane). In both cases, it is calculated with a multiple integral over the object i… WebThe area moment of inertia (also referred to as second moment of area) is a geometrical property of a shape describing the distribution of points around an axis. In classical mechanics it is used as a measure of a body’s resistance against bending. Note that next to the area moment of inertia, the polar moment of inertia is used as a measure ...

WebThe moments of inertia are then called the principal moments of inertia and the inertia matrix is said to be diagonal: I = ( I x x 0 0 0 I y y 0 0 0 I z z) The number of nontrivial inertia matrix elements that you must specify is in this case reduced to three—the principal moments of inertia.
