In the fourth instalment of our monthly fuel-saving series, our expert driver trainer takes a closer look at how correct gear ...

The basic limiting factor for electrical devices is prolonged exposure to high temperatures which deteriorate insulation layers, boundary layers in transistors, and other parts. Since generated heat ...

What if the future of precision mechanics didn’t rely on massive manufacturing plants or multimillion-dollar R&D budgets, but instead emerged from a 3D printer on a hobbyist’s workbench? That’s ...

Gearboxes let engineers adjust servomotors’ operating speed and resulting torque. But understanding the two major types will lead to lower costs and better performance. Engineers have long used ...

Which simple object gives the greatest mechanical advantage — a lever or a wedge? This video explains how the humble fulcrum (a wedge) is turned into a transmission in the form of a strain wave ...

The nice thing about automatic transmissions is that you don't have to think about shifting gears. They appear simple as anything from the driver's seat, but as anyone who knows how automatic ...
