Thanks Rob for sharing such good information i usually collect two to three books and then decide which to read first . After reading your post i have decided that this is going to be my next book . Its aboslutely not strange that Kuprenas wanted to become artist as well because like artist engineers are also creative people they should also think out of the box , both artist and engineer should have knowledge of material, they have imaginary skills ,they have great vision and so on.
Quite an interesting article rob, it is almost nostalgic to me. With all the information shared, we engineers have gone through the same thing, it would be nice to read something we can relate to directly, it always adds interest. And to read both the engineers perspective with an artistic touch seems very interesting. Looking forward to reading it.
If you like books that offer an engineer's perspective with an artistic touch, taimoortariq, look for a book called, "To Engineer Is Human." It was written by Henry Petroski, who also wrote a blog for Design News a couple of years ago. One of my favorite engineering books.
Of course there is a connection between art and engineering. Well engineered objects tend to be esthetically pleasing. Consider the Golden Gate bridge or the Spitfire fighter plane. Many civil engineers are quite consciously architects, too, which was especially true in the 19th century.
Speaking of bridge resonance, look up the Tacoma Narrows Bridge. There are videos online where wind resonance completely damaged a relatively new structure. Resonance in all forms can be very damaging. I do a lot of vibration-specific work, and have seen resonances of structures, big and small, that amplify the load by 100x. That can be very bad when a structure is rated for a safety factor of 2x.
Thanks for the info on the book! I will definitely have this as 'coffee table' reading material.
This is great stuff and I'd love to read this book. The story about the soldiers on the bridge is particularly intriguing. About thirty years ago, there was a similar story about a Big Ten football stadium that had to be beefed up because students in the upper deck would sway back and forth to a cheer that happened to be very close to the the natural frequency of the structure.
Absolutely correct. Do you remember the Ford truck commercial from the 1960's, touting the benefits of "Twin I-Beam" front suspensions? The one where the truck is driven over railroad ties with long poles attached to the cab and the front wheels with two rows of light bulbs bracketing each pole. As the truck is driven over the equally spaced ties, the pole attached to the wheels is smashing lightbulbs like crazy, but the pole attached to the cab rides absolutely level and not a single lightbulb breaks, showing how smooth the ride is. Lee Iococca mentions it in his autobiography, where he asked a Ford engineer how they did it. The engineer's reply was simple: they drove the truck at the speed required to get the suspension to resonate in order to keep the cab of the truck level. If the truck's speed was above or below resonance, the rod attached to the cab also smashed the lightbulbs with abandon. This is analogous to "valve float" where the valves in an internal combustion engine don't fully close when the valve springs reach their resonant frequency.
Basically engineering skills are god gifted one cant develop those skills but he or she can polish the existing skills. According to me Engineering is a passion only those who just get into things and want to explore new and new things can be good engineers . According to me good engineers are those who ask many questions because this is an indication that there brain is working and they are not just grasping the things which taught but understanding as well.
TJ, for that reason and a bunch of others, I still prefer paper books. I'm a book lover. Have been since I was a kid. Loved books and magazines. My first library card was a beautiful thing. My first magazine subscription was just as wonderous -- Boy's Life, followed by The Magazine of Fantasy and Science Fiction.
This book is worth just for the clear explanation on Accuracy and Precision. These fundamental definitions are very important as it is important to differentiate between accuracy, precision, resolution etc. Thanks Rob for the info on this book.
I'm a paper book lover too, Rob. I don't thin k this is just generational: I know several people older than me who really like Kindle. But they read mostly popular fiction and are happy they don't need to keep copies of the books since they don't plan to re-read them. Most of my books are non-fiction, plus some fiction I definitely want to read again.
I've been given two e-book readers as presents, Ann. I lost the first and have gone seven months without reading a book on the second. Maybe it's just a matter of cultivating a new habit, but I still like my paper books.
That's a funny story, Chuck. Maybe you will lose the second one, too :) I like the way books look, feel and smell--I love the smell of new print, especially aggregated in a book store. It beats the heck out of the smell of new electronics.
I agree about the look, feel and smell of a printed book, Ann. I have a favorite chair with a reading lamp where I read books. Electronic books could probably work just as well in that chair and under that lamp, but it wouldn't feel the same.
Chuck, I've got a favorite corner of the small couch with a reading lamp and a stack of books I'm currently reading. One of my friends who likes her e-book for fiction says it's easier to read in bed than a book, especially anything larger than a mass market paperback. She's got a point--I don't even try to read hardbound books in bed.
So, Chuck, during the time you didn't read anything on a e-book reader, did you indeed read paper books? I've toyed with the idea of getting an e-book reader -- I like the cost of e-books -- but I just keep ordering paper books.
I still find the book to be pleasing as a physical thing. It's very efficient. and while the tablet can contain more books, I believe bookshelves are an esthetically pleasing object (collection of objects?) in the home.
I agree Rob--I think bookshelves with books in them are esthetically pleasing also. Plus, they're excellent insulation if you've got lots and lots of them. Years ago I had friends living off the grid in northern California who specifically built bookshelves into the walls for insulation.
Wow. I hadn't heard about books for insulation, but it makes sense. I used to have tons and tons of books (I was an English major). At a certain ploint I decided I didn't need all of these things. So I shipped them off to my little brother who wanted to build a home library. I still have tons and tons of books. They keep rebuilding.
Rob, that was one of the coolest things I'd seen. In this case, they opened up the inside walls and put in bookshelves in between the studs. The books, most of them paperback, work as insulation. Don't know what the R-value is, but it worked and it cut down on the amount of insulation they needed elsewhere. One of so many simple, useful, inventive hippie-style solutions.
I thought it was a nifty idea too, Rob. These were mostly paperbacks, and the small wood-frame buildings were heated with woodstoves, which give out radiant heat. I'm pretty sure this would not be useful in climates colder than Northern California, since the books-in-between-the-studs design disallows more powerful insulation with higher R-values.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
