John, torque those nuts to 42 lb-ft. Ft-lb is energy. Lb-ft is torque. Just a fetish of mine after editing technical documents for a century.  :cheers:

Shoot, Dick, all this time I thought it was just a British thing to call torque lb-ft.

And all this time I thought the Britts used Newtons per Meter N/m which would probably be the same relationship as Lb/Ft...  :|
luckily everyone makes the same mistake so it is universally misused.... (OK, everyone but Dick)  :cheers:

where is Slim---it sounds to me it is more like nouns vs. verbs

Dick, do we all have to get our torque wrenches re-calibrated of just wait for the click?  :? :-o :-D

Where is Slim?  I'm sitting here, eating a bowl of Frosted Flakes and wondering how the heck I'm gonna enter the fray.

I think I won't.  PASS.

Sorry about the minutiae, but since we are all working with torque, whether that produced by our wheel-driving power plants, or to safely tighten our fasteners, it is about time that we all use the correct terminology.

Torque is defined as the radius (r) times the force (F). So, it is obviously NOT ft/lb (lb/ft?) or N/m (Newtons divided by meters).
Sorry, Stainless, it is N-m, not N/m. Actually N "dot" m, but I can't find that math symbol in my font. The "-" is commonly used in texts.
I was the engineering Manager at Stearns Electric for 9 years designing magnetic clutches and brakes. We manufactured TORQUE. I still find it incredible that even torque wrench manufacturers get it ass backwards.

What is really important here is that John's wheels remain firmly attached to this marvelous lakester - and the engine produces enough torque at the appropriate speed to get his 300 mi/h hat.

GO JOHNNY G!

Mayoman, I usually don't bug the hot rodders about ft-lb & lb-ft [no caps] but the engineers  - that's another matter - especially the ones that can't spell hysteresis!  :-o :-D

N•m

To get the dot: hold the ALT key and type 0149

The phenomenon in which the value of a physical property lags behind changes in the effect causing it, as for instance when magnetic induction lags behind the magnetizing force.

"With lube" changes torque value depending on what lube is used. Too slick can excede metal strenght before torque is reached. Several sites give charts, don't remember off the top of my head.

Life is an abrasive. Whether you get ground away or polished to a shine depends on what you are made of.

An easy example of hysteresis is something that's triggered on by one condition but then not triggered off when that first condition is no longer valid.  Like a radiator fan... turns on at 200°F but turns off at 190°.  The 10° gap between on and off means that you get a clean on/off.  Otherwise, if the on/off point was the same temp, you could see the fan turning on and off as temp floats around the trigger point. 

Now back to being on topic again...

Mike, I have been at Stainless' house shaving front tires for the past two days. What a job! The wrap guy stopped by and said we can stop sanding (great news!), that surface finish is good enough to wrap. Over the next week, I will be finishing up all chassis details and begin stripping the car for chassis paint.
