great demonstration

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.

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.

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.

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):

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.)

Using words to let us paint our own mental picture is to me the essence of teaching. Teach us to read and imagine, then present a problem and describe a solution and let our minds create the picture and fill in the details. I read the article and had a pretty good concept of what was being described, when I saw the photo, it was obvious what had been described and the details clicked immediately into place. I think those of us who learned to read before there was television may be luckier than our children who had all the solutions presented visually before they developed the ability to imagine. I always enjoy your articles Professor Petroski.

Ken, You are absolutely correct. A picture is worth a lot of words, but it was my understanding that my column was not to be illustrated. Thanks to Mr. Palmer for inserting the classic photo into his comment.  HP

This article may not be illustrated, but "Engineers of Dreams" is, and I remember the image shown below is in that book.  I've kept it on my shelf waiting for my son to be old enough to understand and appreciate it as he heads towards an engineering career.

Sorry, Mr. P, I had no idea there was any such limitation, it seems I see photo's here quite regularly.  Editor?

Bob from Maine, I'm quite proud of my ability to describe things accurately, but like most engineers regardless their artistic ability, I am always sketching stuff during discussions.  One wouldn't commit schematics or drawings to a written description. Imaginations are way too variable to assure our minds are on the same page. 

I'd seen this fantastic photo some time ago too, (Perhaps in Mr. P's book) and although it all sounded familiar, I still didn't put it together.

I, too, am a big fan of Professor Petroski's books (my favorite is, "To Engineer Is Human"), but I don't recall seeing the photo. Great photo.

Perhaps you didn't know that there are a variety of classes, both live and archived, offered via the Design News Continuing Education Center (CEC) sponsored by Digi-Key? The best part – they are free!
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
We Have FPGAs with On-chip MCUs, but How About MCUs with On-chip FPGAs?
Programmable logic has come a long way from the simple devices we started out with. Remember Programmable Array Logic, or PALs? But where will we be in the next five to 10 years?
As industrial applications increasingly use process control systems utilizing sensor feedbacks to monitor various operating parameters, energy sources and consumption are becoming major factors of a system.
