Dynamic Symmetry:
“Within every equilateral triangle we can inscribe a three-bladed propeller going into the three corners and those propeller blades could be pear-shaped. Each of the blades is the same shape as the others. The pear shape is asymmetrical. We call this dynamic symmetry. (revolvable omnibalanced asymmetry) We have three pears at 120° from one another… The three perpendicular bisectors of an equilateral triangle cross each other at the triangle’s center of gravity, dividing the total triangle into six right triangles, of which three are positive and three are negative. So there are six fundamentals of the triangle which make possible dynamic symmetry. One part may look like a scalene but it doesn’t matter because it is always in balance. Each corner is balanced by its positive and negative-- like a street corner. This is called dynamic balance. Literally all machinery is dynamically balanced in this manner.”
