The first moment of area about the axis s-s is the product of area A and distance Hello, I am having difficulty understanding how the first moment of area is a useful quantity, or even how the formula represents its physical interpretation.So apparently the physical meaning of the first moment of area is where the center of mass of a uniformly dense object is, and that is found by multiplying an infinitesimal area by the distance of that area from the axis. In fact, you may not have realized it, but if you've calculated the centroid of a beam section.

Crosssectional Properties First Moment of Area (Ex 5.1 Part III) YouTube. For complex shapes: For a complex shape consisting of more than one simple geometric shape, the first moment of area is the summation of the product of the area of each section and the distance between its centroid from the reference axis. It is calculated by taking the summation of all areas, multiplied by their distance from a particular axis (Area by Distance)
