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.
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.
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.
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.
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.
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.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
