WebJul 28, 2024 · Figure 17.5.1: The moments of inertia for the cross section of a shape about each axis represents the shape's resistance to moments about that axis. Moments applied about the x -axis and y -axis represent bending moments, while moments about the z - axis represent torsional moments. Just as with centroids, each of these moments of inertia … WebMar 27, 2024 · To calculate the statical moment of area relative to the horizontal x-axis, the section can be split into 4 segments as illustrated: Remember that the first moment of area is the summation of the areas …
The first moment of area is based on the mathematical construct moments in metric spaces. It is a measure of the spatial distribution of a shape in relation to an axis. 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.
