An equilateral triangle is constructed by joining three identical thin uniform rods. Consider two axes 1 and 2 , perpendicular to the plane of the triangle, and passing respectively through the mid-point of a side and the centroid of the triangle. The moment of inertia of the triangle about these two axes, 
and 
, is in the ratio:
