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.

In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
While people may talk about the procurement process, the procurement discipline actually encompasses a number of different processes. They include spend analysis, supplier relationship management, and contract management, just to name a few.
As the Industrial Internet of Things and machine-to-machine communications movements gain speed, some companies are asking themselves, “Wait. How much information do we really want to flow in and out of our premises? Aren’t we supposed to be doubling down on cyber security?”

Extruded aluminum continues to gain traction as a mainstream OEM choice for designing, engineering, and producing component parts. The alloy and the technique have marched aggressively through the awareness and understanding phases and are now solidly in adoption territory.
