SECOND MOMENT OF AREA
Definition
A <SECOND MOMENT OF AREA> is a <Property> that is the second axial moment of area of a plane area (section) about an axis in its plane is the sum (integral) of the products of its elements of area and the squares of their distance from the axis. (I =Integral(r*r)dA, where r is the distance normal from the axis to the area element dA.)
