[DeTomaso] Which axles on which side?

Many screws on a car are sized based on other qualities than their
mechanical strength. For instance, a fender may be held on by say ten 6
or 8 mm screws. The fender itself will rip like tin foil before any of
the screws gives in. If you look at an open wheel race car you'll see
many screws that look scary small in for instance the suspension.

Ok. Perhaps it just seems that the sizing is out of proportion to all of
the other fasteners involved with suspension loads.

An M6 screw has a core diameter of 5 mm. A 5 mm dia rod has an area of
19.6 mm2. An ordinare 8.8 grade screw has a yield strength of 640 N/mm2
and a tensile strength of 800 N/mm2. 19.6 x 640 N is 12544 N whis is a
little less than what a Pantera would require to be lifted in all. 19.6
x 800 is 15680 N which is enough with a margin.

Ok. Not sure about the physics of all of it, but if that's the case,
there are four of them.

A single six mm diameter screw itself is just about able to lift the

That being said, I have sometimes wondered about the faith we put in
that 1/8" thick bearing retainer plate we secure with four six mm
diameter flathead screws. That seems like a weak link. Best not to think
about it to much I decided.
