Yeah, I can't find my solids book anywhere, and I need it, seein's how the company I work for doesn't have Cosmos or Ansys or Algor or anything, and I need to do some rudimentary bending and shear analyses on a couple of beams and shit.

And seein's how it's been more than 10 years since I took that shit, I desperately need a refresher.

So what's your favorite book for the purpose? Either for 314 or 316...

The one I had was the Gere/Timoshenko text. Is the Beer text any good?

11/7/2006 9:15:19 PM

As I recall, Mechanics of Materials (Beer, Johnston, and Dewolf) was fairly decent with good examples. I have an old copy of Shigley's Mechanical Engineering Design, which was fairly useful as well.

Can probably pick up old editions (or paperback versions) online for fairly cheap

really good text

all the editions have been in use for at least 30 years so you cant go wrong

11/7/2006 11:40:25 PM

you need book? you probably shouldn't be working for said company. Also said company probably should hire a PE.

11/7/2006 11:48:40 PM

engineers dont have to know how to do everything

they just have to know where to find the information and be able to use it

whats the best text for fluid dynamics, i cant remember shit

11/7/2006 11:59:14 PM

the most popular book for fluids it seems is "fluid mechanics" by white.

some people have a different "fluid mechanics" by cengel however.
http://product.half.ebay.com/Fluid-Mechanics_W0QQtgZinfoQQprZ43430360

the dept. had switched for a lil while to the cengel version but have recently gone back to the white book.

11/8/2006 12:20:28 AM

I've already got the Shigley text. I had the Gere/Timoshenko text (was it Strengths of Materials or Mechanics of Materials, I can't remember), and that's the one I'm looking for. But I can't remember just which one it is.

If anyone has one they want to part with, let me know. I'm going to be in Raleigh this weekend.

So I suppose you are able to remember every single equation you have ever used and you know exactly when and how to apply them to every situation?

11/8/2006 6:32:48 PM

^nope but im not a PE (yet)... and at the company where I work, PE's are contracted to know this type of shit that nobody else knows... and if they don't know it, they are not hired... but here is probably the best book for zxappeal's purposes... My dynamics teacher made the class buy it... its cheaper than a textbook too

do you honestly think PE's don't reference equations and other material? if you believe that then you are a flaming idiot.

11/11/2006 3:51:26 PM

^so if you owned/ran a firm of PE's then you would be ok with them spending most of their day reviewing alegebra and basic calculus so that they could solve the "rudimentary" problem at hand? If yes then you sir are a flaming idiot.

i'm not sure where you got anything about "spending most of their day reviewing alegebra and basic calculus." the guy was saying he wanted some reference material because he hasn't done much solid mechanics lately.

and if you think that all professional engineers remember absolutely every formula they ever saw in school, you're crazy. about half the engineers i work with are PEs, and all of them keep reference textbooks on their shelves. amazing!

trust me...getting a BS in engineering does not make you expert. it'll probably take years of experience. and even then, if you think you know everything and that you never need reference books, you're sadly mistaken.

11/12/2006 4:20:13 PM

if i ran/owned a firm i would rather have my pe's thumb through a dog eared reference to find a formula instead of wasting time deriving it again and figuring it out. you cant be expected to remember every single formula.

who is talkin about reviewing algebra and basic calculus? there are several variations of formulas for a given situation depending on what exactly the project entails. i would rather have my PE look a formula up and be certain of it than have him sit there and "remember" what it is but not be certain he is right. but hey, if that's your prerogative when you get your PE, we all know who will likely lose their license because they are too ashamed to reference something and damage their ego.

by the way, good way to not answer my question i posed to you

Yea the point I am trying to make is that is that this guy was hired by his company as an engineer, and the last time I checked an engineer should be able to do a "rudimentary" engineering problem even 10 years after getting your degree? I mean if that is not the case, then why does an engineer with 10 years of experience get paid more than an engineer fresh out of school? I mean if you broke your arm and went to the doctor, you would expect that doctor to be able to diagnose a simple broken arm without having to compare your xray with an xray in a medical text.

As far as the PEs, no I do not expect a PE to know EVERY equation, but I would expect them to know (or atleast be familiar with) rudimentary equations. Either way I was being sarcastic with the suggestion to hire a PE to do a rudimentary engineering problem, as that is a completely ridiculous suggestion. Either way I never said that any engineer (PE or not) should remember every equation I was just astounded that someone would need a book. Here is the first webpage that I get with a google search with the words: shear stress bending diagrams beams

not to interrupt here or anything, but I know a very bright engineer who works for CAT, went to an excellent college, graduated with honors and was even valedictorian of his high school. He told me that he and his fellow engineers are always pulling out old books, looking up equations, etc. Even calc stuff. He also said that they sometimes wonder how they ever graduated being that they can't remember all of these things. I just think that sometimes you're not going to use stuff a ton and when you need to, you might need to refresh your memory. It's totally normal in any profession. Doctors, Lawyers and Accountants do it all of the time.

11/13/2006 1:19:12 PM

guys like jethromoore are why other people think engineers are pompous assholes who think they are better and smarter than everyone else.

did it ever occur to you that the guy might not have been doing "engineering work" for the 10 years he was out of school? Or how about if someone is a fluid and thermal science person and all they work with is heat transfer . . . you expect them to be able to go and do vibrations or mechanical design after years of heat transfer without looking at a book?

I work with guys with 20 or 30 years of engineering experience and sure they can spout off from memory many engineering topics. But it is a pretty regular thing for them to look in a book and check things out, refresh their memory before they do something with merit that uses that info. Even if it is something that is "rudimentary".

and while you are right that a simple google search would have probably given him all the info he needed, a text book is almost always >>>>>>>>>>>>>>>>>>>>>>>>>>> web source

that cocky, know-everything attitude is why bridges collapse

11/13/2006 8:02:19 PM

^no I don't have a cocky now it all attitude... but maybe I do because I think that YOU SHOULD BE ABLE TO DO YOUR FUCKING JOB... the last time I checked, a rudimentary engineering problem should be well within the grasp for ANYBODY with an engineering degree. I mean this shit happens EVERY DAY, with EVERY job... if you don't know how to do your fucking job, then maybe you should consider changing your profession.

and btw, its guys like hondaguy and his guys with 20 or 30 years of engineering experience that are the reason why bridges collapse... I mean seriously do you work with the engineers that are responsible for the I-40 fuckups? B/c I wouldn't be all surprised....

As far as my experience, I have worked an engineering internship with John Deere since my freshman year, long enough to know engineers that have 30 years experience and can school a senior in engineering ESPECIALLY in the fundamentals...

11/13/2006 11:45:29 PM

^ the I-40 fuckup was caused by a guy who didn't write down the assumptions (i don't know what they are) because he thought any engineer should know. he basicly has the same attitude as you.

and you are cocky. no matter how much you deny it.

how would someone double checking information to make sure it is right be a problem? In fact, it would be more likely to be correct than to have someone do it from memory and have the possibility of remembering it wrong.

and I work for Northrop Grumman on Submarines and Aircraft Carriers.

11/14/2006 11:55:39 AM

^ for real

I co-oped at the same place, and all my coworkers kept a shelf of old textbooks to reference. After seeing that, I decided to keep my books instead of selling them back (unfortunately I'd already gotten rid of my solids book, that was a good one)

No, not writing down assumptions is not something a cocky engineer does, if somebody is cocky then they would write down all assumptions because they think all the people under them are idiots. I mean I never said that an engineer should never need to hit the books, I said that an engineer should not need a book to solve a rudimentary engineering problem.

"ru?di?men?ta?ry /?rud?'m?nt?ri, -tri/ Pronunciation[roo-duh-men-tuh-ree, -tree] 1. pertaining to rudiments or first principles; elementary: a rudimentary knowledge of geometry."

So as I compared earlier, this would be like a doctor having to pull out his medical text book to diagnose your broken arm by comparing your xray to the example in the book. Or like a car mechanic pulling out the hane's manual to replace the spark plugs in your car. So while you are sitting there waiting getting all pissed off because it is taking so long... you can remember

ok, you have somewhat of a point there. and your point would especially be valid if he was a PE and had been doing engineering work for those 10 years. But like all things . . . when you don't use the knowledge . . . you forget some of it.

yeah . . . we all know a rudimentary concept is a basic concept. things like you posting the definition and bolding the word everytime you type it are part of the reason why everyone in the thread thinks you are cocky or arrogant.

But just because something is "rudimentary" doesn't mean it is in the sense you are implying. If someone is doing some "rudimentary FEA or CFD" that would just mean in terms of those subjects it is not as complicated as it can get. But it would be far from rudimentary in the sense that it is easy and anyone can do it.

11/14/2006 5:41:46 PM

ol' jethro sounds like the type of engineering student that gets by with C's, does some entry level work at an internship and thinks he knows shit. it seems like he still has a lot to learn.

Mechanics of Materials (Beer, Johnston, and Dewolf), 4th Edition

11/18/2006 2:47:32 AM

I found my Gere/Timoshenko text.

My Shigley text has proven to be equally as useful.

this jethromoore really chaps my ass. I'm not a PE, and I don't work for a PE. Add to this I have not used this stuff for more than 10 years, and all the engineers where I work do project management...not structural analysis.

but excuses are excuses, and I really should be able to pull this shit offa the top of my head.

Pray tell...can you tell me how to calculate the second moments of areas of the cross section of a composite or complex beam? Can you tell me right off the top of your head how to calculate the internal stresses in a fixed-fixed beam subjected to various distributed forces and moments?

11/18/2006 10:18:19 AM

a PE probably wouldn't be able to tell you how to do that off the top of his head

with the exception of maybe one that has to do that as their job, and then they would probably just use a computer to do it.

^^^Needs to work a real engineering job. I've worked with top engineers from around the world who have shelves of text for review. GE even supplied a library of collective texts from all engineering backgrounds.

As for the book, you should consider the big blue and yellow PE Exam guide book, it has a lot of solids help and other stuff (Thermo, dynamics, etc...) you may need in the future. Otherwise, I'd say Beer and Johnston has enough problems and examples to suffice.

I'm not saying it was hard, as I found it very easy. But the very statistics you posted go against what you are saying. If almost 60% of the people who take a class get a C or lower, I would tend to say it would be a more difficult topic.

I don't use pick-a-prof, so I don't really know about it. I assume it depends on people submitting the grade they received in when they rate the professor. In which case those stats could be misleading as it is probably more likely that a student that does well would do that kind of thing than a student who fails.
