<< If I remember right, the supplied torque wrench is 11" long, which is
close enough to 1 foot. Applied Mechanics teaches one that the total
length, from the nut to the end of the wrench is the length of the
torque arm, regardless of the bend in the wrench. If you weigh 200
pounds, and REST your weight on this wrench, and your lugs aren't rusted
or oiled, you're looking at about 200 foot pounds. Lightly bouncing can
increase the value 1.5 to 2 times. Jumping can increase it 3-4 times. >>
Correct -- if you assume that the weight is being placed at the
absolute end of the wrench. Our experience has been that most people grip it
with a firm grip, using the full hand, thus moving their leverage point
inward. The main pressure point is closer to the thumb of the right hand than
to the little finger. Generally moving the leverage point about 3"-4". Thus
the general reduction in "torque" mentioed in the earlier post. My comments
were based on experience and observation rather than physics theory.
After while....
