The first moment of area of a shape, about a certain axis, equals the sum over all the infinitesimal parts of the shape of the area of that part times its distance from the axis [Σad] . First moment of area is commonly used to determine the centroid of an area.
The first moment of area is the summation of area multiplied by the distance of the centroid of that area to an axis: |
The first moment of area about the axis s-s is the product of area A and distance. 1st moment of area = A y From this we may define the distance y. |
