How should you position yourself in a free-falling elevator for the best chance of survival?

13QA-popup

Finally, something useful.

C. Claiborne Ray's "Q&A" column in Tuesday's New York Times Science section had the answer; it follows.

Q. If I find myself in a free-falling elevator, is there any position that might increase my chance of survival? (Climbing on top of other people is not an acceptable answer.)

A. The best option would be to lie on your back on the floor as flat as possible, said Eliot H. Frank, a research engineer at the Center for Biomedical Engineering at the Massachusetts Institute of Technology.

"This will distribute the force of impact over the greatest area of your body so that no particular part of your body is subjected to the weight of any other part of your body," he said.

"The impact of the elevator at the bottom of the shaft would subject you to extreme gravitational acceleration, or G-forces," Dr. Frank explained. “The number of G's you experience multiplies your normal weight, so if you experience 10 G's, you would experience 10 times the weight of your body.

"You might think that bracing yourself or bending your legs would help, but at high G-forces, your legs would simply not be able to support the weight of your body," he said. "Even the weight of your own head would be too much for your neck to support."

The folk wisdom of jumping up at the moment of impact is convincingly debunked in a "Mythbusters" video on the Discovery Channel Web site. It would not work unless you could know the precise moment of impact and leap at the same speed the elevator is plunging.

Assume the position.

Toilet paper in a rainbow of colors

Wrote a reader in a comment on yesterday's Toilet Paper Art post: "I like that a lot — brilliant storage idea. But where on earth does one get the super-brightly-colored bung fodder? I'm sure all that dye must be hell on the, what is it — mucosa? — of the nether bits, but it's real purty. I'd like some in vivid royal purple."
