Engineers

can axial stresses be negative? or are they always in absolute values?

thanks
george

Answer is yes in my field but you may mean something different:
Positive axial stress = tension, as in pulling on a cable and elongating it (gets longer, positive stress/strain)
Negative axial stress = compression, as in squashing a column in a building (gets shorter, negative stress/strain)

Do you mean squashing them or pulling their leg?

I'm not usually one of the Architecture types who takes part in such things, but I wouldn't mind seeing one go down right about now.

The economy is doing that well enough right now, no need to add to it. In my field of engineering there is no work, I haven't had an income in 12 months and nothing is in sight for the near future. I may end up being retired about 15 years early. It will be a loss to society too, because someday they will need engineers in my field again and there won't be any left.

It's not a good time for a lot of types of engineering or architecture. Some of the engineering fields are doing great, but others... not so much. A while back there was a study in one of the major newspapers/magazines showing architecture having the highest unemployment of all majors.

How can you tell if your engineer is an extrovert?

he stares at YOUR shoes while mumbling.

I heard something on NPR a few months back saying there was a weeping, crying need for mechanical engineers, particularly with an emphasis on mechanical movements.

Since the OP question has been answered, can we just make this a thread of engineer jokes?

(Disclaimer: I'm an aircraft structural engineer, aka 'stressguy', although I prefer the term 'stress monkey'.)

Mining companies in Australia say they can't get engineers. You can't believe a lot of what you read.

This has been said for as long as I've known that engineers existed. What this usually means is that they can't find the kind of people that they really want to hire, IOW the kind of people that they want to hire don't exist. There are plenty of unemployed people that they could hire if they wanted them, but there are a lot of unemployed people out there that maybe aren't as technically qualified as they should be. My previous employer was in the same boat. We received resumes from people all the time but they just didn't have the college courses and qualifications that we needed in order to do the kind of work that we do. There aren't that many people that can do what we do and do it well. I know that sounds unusual in a country of over 200 million people, but consider how many football players there are in the NFL that can function as a top level quarterback. You can almost count them on your fingers, and this out of a country of over 200 million people? You would think that they would be lined up outside the stadium wanting to get the multimillion dollar contracts, but there just aren't that many of them available. The level at which I can do my job is similar to the level of performance required of a good NFL quarterback.

The people that usually are saying that society needs a lot of engineers are the colleges that want to boost enrollment. They don't particularly care if their graduates can get jobs or not.

Forget what I just said- engineering is easy. All you have to do is remember that if it moves and it isn't supposed to move you put loctite on it. If it is supposed to move and doesn't you put WD40 on it. And you can't pull water and you can't push rope.

I used to not be able to spell engineer and now I are one.

An engineer and a rabbi walk into a bar- FALSE, engineers are too boring to go into bars.
