Re: [T3] Rear End sagging


    My materials engineering is a bit hazy now, but I believe the
torsion bar would become stiffer if it sagged.  Like a paper clip that
is bent too many times gets brittle and then breaks.  I'm wondering if
this stiffness would be noticable or not.
    I guess the main issue is if a sagging bar is about to break.  I
don't believe so.  A simple bump in the road is bending the bar
elasticaly (not permanently).  The sagging bar is in effect the first
permanent bend, and it took 25+ years to happen.  What would really make
that thing break would be a nick, scratch or rust on the surface.  That
would be the stress riser to begin propagating a crack.
