Maybe someone here knows the answer.
Why do text books only give some of the answers in the back of the book? Its always the hard ones that dont have answers!
Homework isnt even part of the grade in most of my classes. if it is, its never more than 5% of your total grade. You do it for your own benefit. But damn if i want to see if my process is right or not, i really have no way of telling.
Ive never been able to come up with an answer to that one.
They don't know the answer to the hard questions. ;D
Because in real life there are no answers in the back of the book. Because sometimes you have to fail in order to learn. Because some instructors weight homework more heavily. Because buy the time you're through the answered easy problems you should have a good handle on the process. Because they want you to ask the instructor questions. or maybe it is just because they're sadists and like to torment college students.
^^^^ [thumbsup]. Heaven forbid someone actually had to learn.
It's called critical thinking.

I'm sorry He Man, but the answer to your question is not in the back of the DMF. [cheeky]
Just Google it...

wrong, its because they publish that in the following edition. go spend more money, yeah that's what they want.
hell if i know im right or not. You have 5 people with different answers and everyone arguing who is right or wrong. :P book doesnt tell you the answer and everyones sure they did it right and the professor wont ever actually solve a problem in front of you, fearing he will be made a fool of! :P

Pssst there is typically a teacher's guide available that does have all the answers. ;)

That is called a discussion
or
different points of view
its what school is supposed to be all about
not in engineering! Theres more than one way to skin a cat, but the cat still needs to be skinned in the end. ie the answer has to be the same no matter how u approach it.

That's the problem...
you guys think everything is so cut and dry.
I can make the beast with two backs up your work by leaving out a washer.
You're not that smart. :-*

Don't know much about that......I'm not a very good engineer.
I can't even get a vanity plate right.

You are right. In civil engineering, 90% of the design is cookie cutter because codes dont require you to think much and everyone complains about cost (and then you wonder why everything ends up looking like a box!). Everyone else, well, that aint my problem! Cookie cutter thinking = high volume = $$. the unique think jobs stuff = no money. Would be great if you are in the middle, but most either fall on the extreme left or extreme right.
Seriously though, its school and i expect there to be an answer!

Actually I was referring to this one... To Engineer Is Human: The Role of Failure in Successful Design (1985), ISBN 978-0-679-73416-
All rocket science can be foiled by people...and you guys aren't smart enough to change that.
Architects make things look good...
the civil engineers decide it can't be done.
What's with the negativity? [laugh] [laugh] [laugh]
Books only have half of the answers in the back so that teachers have the ability to give students a chance to check some of their answers while not doctoring all of their work just to slide to an easy grade. You do an odd problem, you can verify your knowledge of the material is correct by checking against the answers. You do an even problem, and you have to apply that same knowledge without the safety net of the answer section in the back of the book.

Pointy end goes up is a hard concept sometimes.
The whole concept of figuring shit out was challenging for a number of people in my cohort during my MBA. Knowing how to make and educated guess on numbers was something they just couldn't deal with. Sometimes you have to pick numbers based on the available info and be able to defend them.
And I thought you were going to med school.

As an engineer for nearly 20 years, I agree - there is no such thing as making something "foolproof".
"Fool-resistant" is the best that you can hope for. ;)
(and there is no fix for stupid)

Probably your best school lesson right there. This will happen in real life, with no answer held somewhere and no one to pick one over the other. G'wan and work it out-use beer.

the answer is that some idiot will take it upon themselves to figure it out while everyone else makes themselves scarce

use beer.
I prefer beer over energy drinks. but apparently that;s not socially acceptable.

I guess that would depend on the social circle/circumstance too now wouldn't it?

That book was required reading in my "Engineering Ethics Class". And by required reading i mean read a couple pages after I finshed my lab, math and electronics hw.....
