We’ve seen plenty of people 3D printing custom gears over the years, but [Mr Innovative] decided against an additive process for his bespoke component. He ended up using a simple CNC machine that ...

When you push or pull with a simple machine, you are applying a force and doing work. And, if you get more force out of a machine than you put into it, then that machine has a mechanical advantage.

• Planetary units with helical gears, rather than spur gears, have higher torque capacity and run quieter. • Different manufacturers measure and rate backlash in different ways. • Software tools for ...

Machines are all around us, helping us do tasks and work all day, every day. The most basic ones are deemed “simple machines,” but these were, and still are, some of the most essential technological ...

Scientists have demonstrated that large groups of bacteria can turn microgears millions of times larger than themselves, showing potential for "smart" biomechanical systems. Interestingly, the ...
