Where do our engineering words come from?

Where do our engineering words come from?

Where do our engineering words come from?

(OP)
Why do we call it a 'bending moment', it sounds to me like it is taking some time for itself, having a moment.

Shear apparently comes from the Angl-saxon Sceran,

Deflection comes from the Latin Deflectere;

Anyone?

A few seconds of work-out, perhaps?  winky smile

The etymology site below is interesting, but says nothing about "Bending moment" http://www.etymonline.com

Moment sometimes has a meaning of "importance" to it. Like "the moment of truth". The meaning of words sometimes develop in mysterious ways. I think that this could be the case.

RE: Where do our engineering words come from?

I looked it up once.  Something like the root word coming from "momentum," as in the tendency to move or rotate (or to want to move or rotate).

Now I think I'll take moment...




RE: Where do our engineering words come from?

Hard to say. Lots of terms have weird origins, or none at all.

Why do we call "rig pigs", well, "rig pigs"?

engineering words come from drafters, designers and the misinterpretations from managers. laughtears

RE: Where do our engineering words come from?

Two equal and opposite forces are referred to as a couple. As the saying goes - every couple have their moment. And that is how the term moment was derived.

RE: Where do our engineering words come from?

That should really have been every couple has its moment.

Nevermind who made it (up), it's true.

RE: Where do our engineering words come from?

I don't know the origin of moment. It makes me wonder about the origin of the word "momentum" which seems to have the same root although I don't see the tie.

RE: Where do our engineering words come from?

When I visited a crude oil pumping station, which is part of a cross country pipeline, I came across the word " pigging". I wondered what might be this "pig" that they use for "pigging". They said in 30 minutes, the "pig" will reach the station and see it for yourself. I saw the "pig" then.

I still wonder what is the origin of this word "pigging". Is it because the "pig" in the pipeline cleans dirt just as a pig eats sh#t?

RE: Where do our engineering words come from?

A pig usually has bristles, fins, wire, or something around it to clean the pipe. These are typical for crude oil transfer lines where you neet to scrape the "wax" off the walls.

A real pig has bristly hair.

Just guessing.

I still don't know the origin of "rig pigs" though. Anyone?

RE: Where do our engineering words come from?

Pipeline pigs get their name from 19th century UK coal mines.  Due to the moisture of the respiration of dozens of men in a small shaft, the ventilation holes used to clog up with mushrooms and other fungi.  To clear them out, small pigs where sent down the holes to eat their way to the other side.

Sometimes, a marginally sized pig was introduced and due to gaining girth while it ate, it would get stuck and make all manner of noise until starvation shrunk it down.  From that we get 'Sqealing like a stuck pig', a common saying here in Australia at least.

RE: Where do our engineering words come from?

Once they lost enough weight they'd descend to the bottom of the ventilation holes, and fall into the mine. This was regarded as a spectator sport, and the miner's children would all clamour to be taken down the mines to watch. Obviously no one could predict when this would happen, so this gave rise to the phrase 'when pigs fly' for some looked-forward-to event in the indeterminate future.

Some of the fungi had hallucinogenic properties, and if you ate the pig, it gave a feeling of euphoria.

Because only the senior management were able to keep the pigs and eat them once they'd done their job, this is where the phrase 'Living high on the hog' came from.

RE: Where do our engineering words come from?

Originally pigs were pushed or poked down holes to clean them out, hence the expression "don't buy a pig in a poke". Due to cut-backs that mining companies made pigs were replaced by cats tied up in sacks, and hence the expression "don't let the cat out of the bag".

RE: Where do our engineering words come from?

I have more, but I may be accused of flogging a dead pig.

RE: Where do our engineering words come from?

Wow!  I never knew that stuff about pigs (and cats).  I've learned my quota for the day.

RE: Where do our engineering words come from?

lewtam ... you could also be accused of Hogging the thread if you continued.

I'm getting boared with this line of discussion.

To be honest, I'm pig-ignorant about this subject.

RE: Where do our engineering words come from?

First post: in Physics the terms "moment of inertia", "moment of gravity", etc., are used to describe a torque or twisting force, or a product of some physical force unit and its distance from point of origin, i.e. around an axis, applied to describe momentum, such as angular momentum. One place I have found sometimes useful in search of such questions is www.wikopedia.org, however use caution as some of the postings have been questionable, at best.

Really?
 Are they as questionable as some of the postings in this thread?
B.E.

RE: Where do our engineering words come from?


@edav:

That's a good one!

But this is an open forum, maybe a moderated one. A site that purports to be kind of an encyclopedia has got watch out for errors.
