Novel ratchet mechanism uses a geometrically symmetric gear driven by asymmetric surface wettability
The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous rectification. It is a ...
A team of New York University scientists has created a gear mechanism that relies on fluids to generate rotation. The invention holds potential for a new generation of mechanical devices that offer ...

The Antikythera mechanism worked like a computer 2,000 years before electronics existed
Greek artisans built a bronze device around 80 B.C. that could track Olympiad cycles, predict eclipses, and model planetary positions through interlocking gears, all without electricity, transistors, ...
Beyond grinding gears: Researchers clarify contact gear fatigue mechanism, report on latest in field
Researchers assessed recent studies on gear contact fatigue — when the gears that keep engines, helicopters, wind turbines and more in operation fail — to better understand the mechanisms that lead to ...
