Question

Geometrical moment of inertia definition

Answer 1

The 2nd moment of area, also known as moment of inertia of plane area, area moment of inertia, or second area moment, is a geometrical property of an areawhich reflects how its points are distributed with regard to an arbitrary axis.

Answer 2

The area moment of inertia is a property of a two-dimensional plane shape which characterizes its deflection under loading. It is also known as the second moment of area or second moment of inertia. The area moment of inertia has dimensions of length to the fourth power.
