If I follow you logic on this, and since I don't drink beer, I should be
about 50 lbs!!! However, I seem to be gaining. Could it be the extra's that
the rest of you are drinking while taking off (or rounding off, whichever
you prefer) nuts and bolts that is somehow attaching itself to me? Since
energy cannot be created or destroyed, can it be psychically transferred
(kind of like a Latoya thing?) to those of us that need this PEE rating?
Just curious.

Subject: how to measure what you do
***from the jag list***
Someone asked if a person who does not drink beer can actually perform a "0
Beer" job on a car. He he he... how naive we are! It's not that simple my
friend. Note that I've removed the <wob> tag from this topic as any
discussion about beer is certainly not a waste of anything.
Now, think about the scientific definition of "Work," and stay with me on
this:
The average (non-light) beer has 167 calories. A 6 -pack therefore has 1000
calories (1 kilo calorie - 1 kcal)1 kcal = 3.97 Btu.
We don't like to think of British things when we work on our cars, so we
convert 3.97 Btu to 0.001163 kW hours.
0.001163 kWh = 0.00156 hp (now we're talkin' - HORSEPOWER)
0.00156 hp = 51.48 lb-ft/min (0.00156*33,000)
Now, for example, an E36 BMW has 20 lug nuts. If each is to be torqued to
74 lb-ft to accomplish the mounting of a set of R1s,that's 1480 lb-ft
total. If performed in an hour, that's 1480/60 which equals 24.67
lb-ft/min.
Now, divide our expended energy of 24.57 lb-ft/min by a six pack's rating
of 51.48 lb-ft/min and you get .478 six-pack, or roughly 3 beers.
Yes, mounting R1s for the next day's autocross is typically a three beer
job.
Knowing that energy cannot be created or destroyed, you HAVE to drink three
beers to accomplish this job or the universe will be out of balance. Of
course, you can eat a Powerbar to balance the universal forces, but the
fact remains that mounting four tires will ALWAYS have the Pilsner Energy
Equivalent (or, PEE rating) of three beers.
So you see, each job we perform on the car will have it's own PEE rating
whether you drink beer or not. The fact that you don't drink beer does not
change the reality that a certain job expends
the equivalent energy of a fixed amount of beer - there's no short cutting
the laws of physics here.
