A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system.

Dive into the impressive process of crafting a high-strength spur gear from old ship sheets. Watch as expert mechanics skillfully cut gear teeth on a lathe, transforming raw materials into precision ...

[Steve Mould] shows us a different take – the experimentation kit called Spintronics, which goes the mechanical way, using chains, gears, springs and to simulate the flow of current and the ...

When linked together, gears amplify an input force to maximise an output force. In Nightingale, Mechanical Gears is considered a Component which means that it is an item primarily used in crafting ...

Japanese designer Haruki Nakamura makes moving ornaments completely out of paper, imitating movements seen in mechanical gears. The self-taught designer has videos that are instructional ...

A gear close gearA gear is a mechanical part with teeth that interlock with another gear or belt to transfer motion and power while changing speed, or direction in a mechanical system. is a ...

This video explores different methods that can be use to amplify a force, and focuses on three types of machine - levers, ...

Mechanical devices can change one form of force ... and the velocity ratio has been calculated as 3. Smaller gears with fewer teeth turn faster than larger gears with more teeth.

A mite, less than 1 mm in size, approaching a microscale gear chain. (Image: Sandia National Laboratories) The one main criterion of MEMS is that there are at least some elements having some sort of ...
