The stress coefficient "k" is integrated for the
values " n" and "Mn". The stress coefficient takes
approximately the maximum calculated tension of
the spring body into account.
Torsion springs are not tempered, since the
bending stress is in the direction of coil. This
means that leg bending and shortening can be
carried out later on torsion springs.
