Default How does Bowden cable work

presented the following explanation :
I can't put the sheath in compression as it runs from the trap of the bath up
to the knob on top of the bath so needs to flex around contour of the bath.


Usually Bowden cables work with the inner being pulled (tension)
against the outer, which is compressed. Outers have limited ability to
withstand tension, because if too much tension is applied, then they
easily stretch.
