Author and professor Steve Radzevich discusses the third revision to Dudley’s Handbook of Practical Gear Design and Manufacture, and the essentials gear designers should know.

In a paper published Sept. 13 in the UK journal, Science, zoologist, Malcolm Burrows, and mechanical engineer, Greg Sutton, revealed their findings about this singular insect.

The gears are located at the top of the insects’ hind legs (on segments known as trochantera) and include 10 to 12 tapered teeth, each about 80 micrometers wide (or 80 millionths of a meter).
