Cindy- Presumably it was Galileo who discovered the true catenary arch.
Believe me it doesn't take a mathatician to get the answer.
The catenary was used extensively to build many of the great
cathedrals in Europe. As the arches get bigger and the thrust
of the curvature became more precarious, large exterior
buttresses were attached. These are known as "flying buttresses". The best
example is Notre Dame in Paris.
For kiln building the catenary is about the only shape which
does not need to have a steel frame or other supporting devices
since the curve is in perfect proportion to carry thrust from the arch (the
flue) downward to the base.
To learn how to arrive at the catenary arch for making a
kiln, very simple and true, without math, go to: www.R2D2u.com and
meet CATERINA CATENARY. This cartoon illustrated eManual
provide you with full description, diagrams, and explanations.
