Standard Deviation?

Good grief, guys.

By the time the ambient temp and hunting altitude/humidity changes; you're using a different lot of primer and powder; AND bounce it off a few twigs getting to the the Muley (who never took geometry, much less trig).... only St Thomas Aquinas would be impressed.

[QUOTE-dmazur]Torque can be explained very quickly. In fact, it only takes a moment...[/QUOTE]

Good one!

Does the torque explaination have all these graphs and stuff????? Cause if so, then I think it will take more than a second.

From Wikipedia -

Torque, also called moment or moment of force (see the terminology below), is the tendency of a force to rotate an object about an axis,[1] fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist. (emphasis added)

http://en.wikipedia.org/wiki/Torque

The attempt at humor was that "torque" and "moment" are sometimes used as synonyms, depending on whether you are dealing with a physicist or an engineer. This was thin, at best, and had nothing to do with the amount of time required for an explanation.

Most folks are familiar with "torque specifications", or at least have heard of tightening a nut or bolt to x ft-lbs. They may nor may not be able to determine how many lbs of force are required on an 18" wrench to generate 75 ft-lbs of torque on a lug nut. (Answer: 50 lbs)

This is buried in the Wikepedia article under Special Cases and Other Facts, Moment Arm Formula, and it's really all most of us need to know about torque.

So, that "special case" is an explanation of torque, without graphs and stuff.

Mathematician Wars on THR - imagine that!

Well, who ever is full of xxxx can always work it out with a slide rule!


PS - dmazur: "...it only takes a moment" - clever fellow, too funny!

I just wish I could get a graph or something for my question!! ;-(

What do you want to know about torque?

 

[Shadow 7D]

Not much, that would be why he is asking

Actually, mathematically many forms of distribution can be forced onto a data set, but until you look at the data and analyze it, finding your population, whether continuous or not, you don't come to the correct way of normalizing your distribution, I have a advanced college statistics book if anybody wants it, used twice and poorly understood.

 

[MEHavey]

"Statistics" and "Torque" are apples & oranges.
They have nothing to do with each other.

That said,....

If I hold a 1-lb weight in my hand, that weight causes 1-lb of Force straight down on my hand.

If I have a wrench 1-ft long applied to a bolt, and I put that same 1-lb weight on the end of it, the bolt is twisted with "1 Ft-lb" of TWISTing force called Torque, or "Moment"

If I put 2-lbs on the end of that 1-ft wrench, I get 2 ft-lbs of torque
If I put 1-lb weight on a two-foot wrench, I (again) get 2 ft-lbs of torque
If I put a 10-lb weight on that same 2-ft wrench I get 20 ft-lbs of torque

Torque is twisting force
The more the force on the end of a bar, the more the torque.
The longer the bar, the more the torque.

So simple even a caveman can do it.
