Three identical point masses of mass M are fixed at the comers of an equilateral triangle of sides I as shown.
Three identical point masses of mass M are fixed at the comers of an equilateral triangle of sides I as shown. Axis Aruns through a point equidistant from all three masses, perpendicular to the plane of the triangle. Axis B runs through M, and is perpendicular to the plane of the triangle. Axes C, D, and E, lie in the plane of the triangle and are as shown. Part (a) Determine an expression in terms of M and / for the...

I first discovered that the
area of the equilateral triangle is
. I then considered a point in the center of a triangle, and then
connected it to each of the vertices. From there I gathered that
each of the 3 triangles formed by these line segments gave an area
of
. Please use the pigeonhole principle to explain.
