Area Moment of Inertia - Filled Right Triangle
The second moment of area, also known as moment of inertia of plane area, area moment of inertia, polar moment of area or second area moment, 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 for a shape is easier to be calculeted with respect to a parallel axis or with respect to a perpendicular axis through the centroid of the shape.
The formula calculates the Moment of Inertia of a right triangle of base b and height h in respect to an axis collinear with the base of the triangle (one of the sides adjacent to the right angle)

|b||Base of right triangle (one of the sides adjacent to the right angle) (mm)|
|h||Height of right triangle (the other side adjacent to the right angle) (mm)|
