returns bending radius and angle for a compressed line

Description

Helpful parameter:
Steel Slim=355; E=200000
PA12 Slim=36; E=1240 (PA2200 called at EOS)
The relation between a circle segment and the chord (segment crossing line) can be solved only by a numerical search using fzero.
if s < l than the line is streched.
if s = l than the radius would be inf
if s > l there is a solution
In reality there is a minimal radius for bending because of material stress
