Moment of inertia of thin plate
WebThe second moment of area, also known as area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with respect to an arbitrary axis. The unit of dimension of the second moment of area is length to fourth power, L 4, and should not be confused with the mass moment of inertia. WebIn physics and applied mathematics, the mass moment of inertia, usually denoted by I, measures the extent to which an object resists rotational acceleration about a particular axis, and is the rotational analogue to mass.Mass moments of inertia have units of dimension ML 2 ([mass] × [length] 2).It should not be confused with the second moment of area, …
