Delta and SWA 717's a done deal?

[Daddy]

Tex, I agree on all points except the growth. The real "synergy" is the pricing power in the marketplace by having one less airline to compete with on price. Let's all hope AMR and USAir hookup...among others. The less competition the better for us.

I can agree with that.

Aussieflyboy knows that all engines and motors are really called "Donks". Scorboard II knows more than Darth Vader has forgotten. He once taught a German shepherd to bark in Spanish.

Word.

Dude you are my hero!

 

[scoreboardII]

It sounds like Aussieflyboy and ScoreboardII might have learned something.

I suppose this means nothing:

mo·tor/ˈmōtər/


Noun:A machine, esp. one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device...

You guys are worse than the spelling Nazi's.

 

[Hamfighter]

I always thought of it as electric motor vs gas engine. Oh well, wrong again I suppose.

*****Engine vs Motor
thread1010-206484

Leaving out the newer renditions of "engine" (i.e. search engine, graphics engine, economic engine etc.), I'd like to hear if anyone has a conclusive explanation of the difference. The context is, I had a discussion with a colleague to the effect of, an engine is a motor which converts thermal energy to mechanical energy, and a motor is a machine that converts energy to motion (or propulsion). So my contention is that all**********engines are motors, but not all motors are engines. he was of the opinion that the two terms are virtually interchangeable, citing the prevalence in the Automotive world to refer to the thing under the hood as a "motor" or an "engine".

Unfortunately, I see a lot of ambiguity in the dictionaries I have looked at, leaning towards my opponents position. Most of them seem to use each word in the definition of the other. I think that dictionaries are essentially fluid documentation of common speech, not definitive technical reference resources, so the fact that lots of people have been misusing the terms has now become reflected in the dictionary definitions.

Thoughts?

To me, with a interest in railroads, it is clear what one is talking about when an engine in the internal combustion machine and a motor is the electrical machine the turns the axle (and the whole thing is a locomotive).**********So I'm with you that there is a difference, and I'd extend it out to engine and motor are two different things even though common usage is sloppier than that.**********Maybe as hybrid cars become more common there will be a clearer distinction between the terms as people need to distinguish between the engine and the motors.

From Merriam-Webster online dictionary:

Engine:
4: a machine for converting any of various forms of energy into mechanical force and motion; also : a mechanism or object that serves as an energy source <black holes may be the engines for quasars>

Motor:
1: one that imparts motion; specifically : prime mover
2: any of various power units that develop energy or impart motion: as a: a small compact engine b: internal combustion engine; especially : a gasoline engine c: a rotating machine that transforms electrical energy into mechanical energy

I would never refer to an electrical motor as an engine!

jraef, I agree with your thoughts!

While it is common and there are some fairly recent threads that refer to "motoring" an engine, who'd ever think to say in the same context "engining" an engine?**********But according to Merriam above that would be proper.**********Go figure.

Sorry, but I don't trust civilians with technical definitions.**********I used to know the difference in the definitions but I can't remember it right now.

Thought provoking question.

I think that somewhere way back the word motor comes from the same ancenstry as the word motion.**********One example "motor skills".**********(skills to produce motion).

Brings to mind a question about the underlying root word in engine and engineer.**********Are we called engineers because we are associated with technical things like engines?**********Or do engine and engineer both derive from the same word related to our ability to produce an effect.**********Beats me.

Clearly in the electrical world we like to reserve the word motor for electric motors. But also there are air motors.**********Are they called air motors because they do the same thing as an electric motor, but with air?**********Or because they produce motion? The latter, I think (but I'm not sure).**********It definitely irritates me when my wife refers to the motor under the car hood.

I agree the terms motoring an engine would be reserved to the context of an engine driving a generator and when the generator is motored the direction of power reverses.**********That seems limited to electrical contexts.

Bottom line. Beats me. I would be interested to hear an authoritative rule which covers all applications, but I doubt there is one.

In aerospace, rockets are considered "motors" as well.

Whereas I'd call them (and any jet engine I can think of except plasma drives) internal combustion engines.

Although they have different root words, they are in effect, the same thing to a degree.**********The class of mechanisms we call motors is a subset of what we call engines; engines being the broader category.**********We are called Engineers, not Motoreers.**********heheehehe

Given that explanation, it does make sense to motor an engine (create motion with the engine), but not engining a motor (convert the motor into motion).**********

we're not called engineers cos we play with engines, it is because we are ingenious.

Engine is a subset of motor in this context.

The same Merriam-Webster online previously cited by pmover tell this about "engine" etymology**********:

Etymology: Middle English engineering, from Anglo-French, from Latin "ingenium" natural disposition, talent, from "in"- + "gignere" to beget — more at kin

But for engineer :
Etymology: Middle English engineour, from Anglo-French, from enginer to devise, construct, from engineering

And motor :
Etymology: Latin, from "mov?re" to move

We have commonly only one word in french : "moteur"
L'Office québécoise de la langue française suggest, for the same "engine" definition as from the M-W, both "engine" and "motor". But it proposed "engine" first and would be prefered since they rule it in 2001 and the word "motor" in 1993. They newer definition takes priority. Also, for "moteur" in aerospace it proposed "booster" ("launching rocket" as near synonym) but a rocket is a "fusée".

"In aerospace, rockets are considered "motors" as well. "

At the rocket factory where I worked as a young engineer, I was roundly berated for referring to a solid rocket as an engine, or a liquid-propellant engine as a motor.**********Frankly, I still claim hogwash, since the elder COB (Crotchety Old Bustard) could not supply a definition that made sense; I agree with the OP's derivation, which implies that rockets are both.

An engine is any useful man-made contrivance that takes in power and possibly raw material, and converts those into a useful output.**********This is roughly abstracted from wikipedia's article on engines, and is based on its derivation from the latin, "an invention".**********Thus we have Babbage's Difference Engine, or the Middle Ages' Siege Engines, in addition to our modern car engines.

A motor is a sub-class of engines, one that produces motive power as its primary output.**********

But, go figure, we are talking about the English language here, and thus have outboard motors on sale next to motorcycle engines, both of which may have electric motors for starting.**********Just don't call a solid-fuel rocket an engine, or you will get sneered at.

electricpete, regarding this"... Are we called engineers because we are associated with technical things like engines?**********Or do engine and engineer both derive from the same word related to our ability to produce an effect.**********Beats me...:"

I think you should look at the old latin "ingenium", which means "to be good in something", "somebody who uses its brain" or "innovator". I hope I have managed to explain its meaning.

At least this is what I was told at my first day at engineering school (wrongly called engineering university).

I suppose this means nothing:

Noun:A machine, esp. one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device...

That is for the general public. The professionals know the difference. Next time you need a new fan motor for your air conditioner tell the repair man you need a new engine and see what he tells you. Start acting like you know what you are talking about. Remember the old saying : rather a man think I am a fool than open my mouth and remove all doubt".

So why is GM called General Motors ?

Did they start out by making electric cars back in 1908 ?
