Good lord Mr. Petroski! I know you are a writer, but why spend so many words describing such a wonderful photo, but leave it to Mr. Palmer to supply one!?

Nontheless, I always enjoy your articles. (And some of your books too.)

This is definitely a great way to illustrate concepts of stress and strain! I'll have to keep this technique in mind when trying to explain mechanical problems.  By the way, here is a picture (from Wikipedia):

What I really like about the human model described here is that the humans could feel the tensile and compressive forces, rather than just imagine them. Seems like it would be a great exercise for engineering students.

I agree.  The human model is a very good demonstration.  Too bad we don't see more creative explanations like this for people to see the value and innovation in modern structures.

The story of that demonstration of the concept of the bridge is really interesting.  Before the days of electronics to be able to get such a concept across was a difficult proposition.  The solution is very good and filled the bill well.

I have been on that bridge, by the way.  It is a great view.

More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Kevin Gautier of Formlabs describes the making of a carbon fiber mold for an intake manifold, using a $3,300 3D printer, during Medical Design & Manufacturing Midwest.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
