THE STRESSES OF THE PEDERSEN

The triangulated frame and fork are designed to afford the maximum strength with the minimum of weight. The same principle is now almost universally adopted in the bridge roof, and other constructions where lightness with strength are specially desired, indeed, this is the only construction which enable strains to be properly met and distributed.
The tubes are in pairs throughout, each pair making conjunction with the bottom bracket or other portion of the frame a triangle, thereby imparting great lateral stability to the machine, and resistance to the pedal pressure.

” As a matter of fact, a more properly geometrical frame was produced in the 1990s using small tubes triangulated in pairs on the same principle as modern racing-car. ( ( (Space-frame ) “

Pedersen used the newly build FORTH BIDGE in Scotland to explain the “Cantilever Principle”

The Forth Bridge is here explained by the tension absorbed by thearms of two side fellow man, the sticks take the compresion

Pedersen workers explaining the very same principle in the front fork
