Tour de France Still Needs Steel  New technology debuting at the Tour de France includes "old" materials like good old reliable steel — neither advanced carbon composites nor titanium apparently could compete. Many of the top-of-the-line racing bikes use ultra-lightweight materials, but new designs using bushings, bearings, and gears still rely on old faithful steel.

Bullish for Bearings
 Bearings are the unsung heroes in so many mechanical designs — yet without ball, roller, or plain bearings, planes don't fly and cars don't hit the road. A recent report by the Freedonia Group notes that bearing demand is increasing at 3.1% annually, contributing to a $10.4 billion market by 2011.

Materials Fulfill All Functions
 Grading value and price advantages, convenience, performance characteristics, longevity, and even availability are only a few of the factors that engineers consider when specifying gasket materials. To help users decipher which material is best for the application, a new brochure rates 10 advanced materials and describes how they can handle the toughest jobs.

In Search of Failsafe Seals
 One infamous failure — the O-rings in the Challenger space shuttle — constantly reminds engineers of how important seals really are. This primer on seal failure analysis examines the three ways a seal can fail and how to analyze the environment, design, and elastomers contributing to common failures. A multiplicity of specific topics addresses most of the possible permutations.

"Swab the Decks" Reliability Resource
 The U.S. Navy's Naval Surface Warfare Center has published the "Handbook of Reliability Prediction Procedures for Mechanical Equipment." It encompasses springs, bearings, seals, gaskets, and virtually any kind of mechanical equipment. The in-depth treatise shows how to identify critical failure modes and thereby optimize mechanical equipment performance.

The Ultimate Robotic Tools
 The Martian rovers, Spirit and Opportunity, have been exploring the landscape of Mars for more than three years. One onboard tool is of the rock-abrasion variety. It's designed to grind into Martian rocks and allow the rovers' sensors to look inside and see what's there. That should be interesting.

Multifunctional Mechanical "Fish"
 Call it an adjustable wrench plus a screwdriver and then add LED lighting. Wait a minute, you need to add a multiplicity of other functions: a high-carbon stainless steel blade, a carabiner (quick disconnect system), and a money clip. Strap on the Guppie, and you're good to go with the best of scouts.

 "New" vs Conventional Engineering
Engineering school teaches that conventional engineering is based on physical laws that are described by equations and dimensionally homogeneous. But what if a new theory of engineering could show that problems are solved with the variables separated rather than combined? You may want to read more about the concept of nonlinear engineering phenomena and judge for yourself.
