Problems on moments of area
WebbThe 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 I Webb12 nov. 2024 · The moments of inertia about principal axes, are called principal moments of inertia, and are the maximum and minimum ones, for any angle of rotation of the coordinate system. For a rectangle, axes x and y are both symmetry axes, and therefore they define the principal axes of the shape.
