Subject: RE: Tubular contro arms, any interest??

[Larry C. Leung]

As I recall in design of machine elements course in my former engineering
days, steel can 
be designed for infinite life. Stainless, nor Aluminum cannot. I actually
have really wondered about
all of the recent cars whose structure (A8, NSX) or suspension (Corvette
C4-6, Porsche),
are of aluminum, which has a fixed fatigue life. At least aluminum
airframes get replaced in 
the course of normal maintenance throughout a planes life, but how many
Corvette owners
replace their control arms? Would one fail, perhaps in an inopportune
place such as a track
day, or even worse, at high speed in traffic? And whom is ever checking
an A8's shock 
towers or rocker areas for cracking, as they do with aircraft?

Ok, my statement I made about preferring quality steel over stainless....
I
cannot explain why, apart from the basic strength issues. I know there
other
reasons, I just cannot recall.  Anyone care to add?

Agreed, Chromoly would be nice.

I
would far prefer to see some sort of quality steel, powdercoated or
plasticoated.
