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.

Transient-voltage-suppression diode technology eliminates surges and enhances vehicle safety.
Industrial workplaces are governed by OSHA rules, but this isn’t to say that rules are always followed. While injuries happen on production floors for a variety of reasons, of the top 10 OSHA rules that are most often ignored in industrial settings, two directly involve machine design: lockout/tagout procedures (LO/TO) and machine guarding.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
While risk management sounds like one activity, in order to be conducted effectively, it must be broken down into three sub-components: risk assessment, risk monitoring, and response planning.
While many larger companies are still reluctant to rely on wireless networks to transmit important information in industrial settings, there is an increasing acceptance rate of the newer, more robust wireless options that are now available.
