We’ve probably all used gears in our projects at one time or another, and even if we’re not familiar with the engineering details, the principles of transmitting torque through meshed teeth are pretty ...

In an experiment reminiscent of the "Transformers" movie franchise, engineers at Princeton University have created a type of material that can expand, assume new shapes, move and follow ...

A gearbox driven by an external magnetic field can power tiny but powerful robots that crawl like a caterpillar or jump almost 40 times their own height, despite having no batteries or motors on board ...

Bad things can happen when the mechanical gearbox in a megawatt-scale wind turbine gets overstressed. An unexpected wind gust can drive turbine blades hard, so hard that the torque on the gearbox they ...
