Area Moment of Inertia of a Regular Hexagon about a Centroidal Axis

The second moment of area, also known as the moment of inertia of plane area, area moment of inertia or second area moment, is a geometrical property of an area that reflects how its points are distributed with regard to an arbitrary axis.

The second moment of area for a regular hexagon equals edge length to the fourth power multiplied by a constant factor.

Formula

QuantityVariable["J", "SecondMomentOfArea"] == (5*Sqrt[3]*QuantityVariable["a", "Length"]^4)/16

symbol description physical quantity
J second moment of area "SecondMomentOfArea"
