The first moment of area is a geometric property that measures the distribution of an area about a particular axis. It is often used in engineering and structural analysis to help determine the centroid of a shape or area. The first moment of area (denoted as \\( Q \\)) is defined for a specific axis and is calculated as the integral (or sum) of the area times the distance from that axis.
