Area Moment of Inertia Converter
Area Moment of Inertia or Moment of Inertia of 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.
The general equation for Moment of Inertia for bending around an axis can be expressed as
Iaxis = ∫ y2 dA (1)
where
Iaxis = Area Moment of Inertia related to an axis (m4, mm4, in4, ft4)
y = the perpendicular distance from axis to the element dA (m, mm, in, ft)
dA = an elemental area (m2, mm2, in2, ft2)
