Area Moment of Inertia - Metric units. The moment of inertia of any shape in respect to an arbitrary non centroidal axis can be found if its moment of inertia in respect to a centroidal axis parallel to the first one is known.
Calculation of Properties for Rectangular Tube. The moment of inertia second moment of area of a rectangular tube section in respect to an axis x passing through its centroid and being parallel to its base b can be found by the following expression. Formulas for the elastic deformations of uniform thin-walled open members under torsional loading.
These section properties are calculated with respect to the major axis only.

Area Moment of Inertia or Moment of Inertia for an Area - also known as Second Moment of Area - I is a property of shape that is used to predict deflection bending and stress in beams.
Moment of inertia denoted by I measures the extent to which an object resists rotational acceleration about a particular axis and is the rotational analogue to mass which determines an objects resistance to linear accelerationMass moments of inertia have units of dimension ML 2 mass length 2It should not be confused with the second moment of area which is used.
