SANTA BARBARA, Calif. — To evade friction, try taking a quantum shortcut. Two teams of physicists are building tiny machines designed to operate with the maximum possible efficiency. According to ...

Moog Inc., East Aurora, N.Y., and Thompson Friction Welding, Clinton Township, Mich., recently teamed up to develop the world’s largest linear friction welding machine. The new machine is capable of ...

Thompson Friction Welding'sE100 extends the use of linear friction welding through its ability to weld anarea nearly twice as large as previously achieved (a surface area of 10,000 mm 2).It also uses ...

Spring technology for damping is relatively old. Stagecoaches had leaf springs, early trains had large, crude, coil-spring buffers (to absorb shocks when cars bumped together) and early automobiles ...

How do you measure tight-tolerance parts on a plate gage without stumbling into subtle errors? George Schuetz explains his process.

DURHAM, N.C. -- Duke University materials scientists have developed a computer model of how a "quasicrystal" metallic alloy interacts with a gas at various temperatures and pressures. Their advance ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...
