To detect the quantum friction of empty space, scientists are going for a spin. A twirling nanoparticle, suspended in a laser beam inside of a vacuum, can measure tiny twisting forces, making it the ...

"Good morning, Mr. Brandes. Your mission, should you choose to accept it, is to find out why a long-serving Chrysler 727 TorqueFlite three-speed automatic transmission suddenly and mysteriously ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? This is how I knew I needed to learn how to use a torque wrench: It was Christmas Eve ...

Measuring torque when installing threaded fasteners is the best indicator of future joint performance, right? Actually, bolt tension is a better performance indicator, but measuring torque is far ...

Designers typically qualify clamp force of a bolted joint by the amount of torque applied to fasteners holding it, either as they're tightened or after the fact. The approach may be adequate for many ...

In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...

Using a full-scale dynamometer for the testing of friction materials for brake applications is a cost- and time-intensive method as it requires the rotor and brake pads to be in their final form ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.
