• No more "girlie man" gears
  blanks can triple gear cost. A GEAR EVOLUTION. Plastics primarily serve in involute gears, most commonly spur gears. Historically, plastic gear designs mimicked those of successful metal gears. But new design strategies for boosting power, improving function, and lowering costs are pushing...
• Monitoring Composite Structures
  The advent of the Boeing 787 and the Airbus A350 has wrought a step change in airframe construction with composite materials largely superseding what was previously made from metal. But moving away from tried and trusted alloys to save weight and add strength has brought a set of new challenges...
• "Tight" is not necessarily leaktight
  Keeping separable fluid fittings secure can be a challenge. Here are a few helpful tips. Jet engines use secondary locking mechanisms to secure fluid fittings. Most separable fluid fittings are of a flare or flareless design. These, as well as some face-sealing types, rely on metal-to-metal contact...

• Rugged Bearings Hold the Weight of Heavy Equipment
  . Reversing shear stresses cause fatigue wear and cracking. Finally, plastic deformation can permanently squeeze out bearing material from between the two surfaces. One common thread among all the material-removal mechanisms is the contact. Rugged Bearings Hold the Weight of Heavy Equipment | Machine...
• MICRO: Testing liquid-handling system components to ensure purity and reliability
  Edwards (Santa Clara, CA), for example, has adopted specifications for particle release and metal extraction from the components used in its chemical delivery systems. Another major concern for semiconductor manufacturers is component reliability, since equipment failures result in costly fab downtime...
