WebThe first moment of area is the integral of a length over an area – that means it will have the units of length cubed [L 3 ]. It is important because it helps us locate the centroid of an object. The centroid is defined as the "average x (or y) position of the area". Mathematically, this statement looks like this: WebMar 27, 2024 · Fundamentally, the moment of inertia is the second moment of area, which can be expressed as the following: I x = ∫ ∫ y 2 d A. I y = ∫ ∫ x 2 d A. To observe the derivation of the formulas below, we try to …
