  4. Second moment of area. The second moment of area, or second area moment, or quadratic moment of area and also known as the area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. The second moment of area is typically denoted with either an (for an axis that ...

  6. Jul 28, 2021 · We can sum up the resistances to bending then by using the second rectangular area moment of inertia, where our distances are measured from the neutral axis. I = ∫A(dA ∗d2) (17.5.1) (17.5.1) I = ∫ A (d A ∗ d 2) Assuming we put the origin point at the centroid and that the x x -axis is the neutral surface, the distance from the neutral ...

  8. This means that the resistance to bending provided by any point in the cross section is directly proportional to the distance from the neutral axis squared. We can sum up the resistances to bending then by using the second rectangular area moment of inertia, where our distances are measured from the neutral axis. I = ∫A(dA ∗ d 2) Assuming ...
