I’d never wondered how any of the following things worked, but the GIFs are so pleasing I thought you might want a bit of a look yourself:
A Geneva drive translates a continuous rotation into am intermittent rotation.
It was first used in clock apparatus made in Geneva, Switzerland, hence the name. It’s also used in other mechanisms, like the movie projector: the film isn’t passed continuously in front of the lens. Rather, each slide is held up for 1/24 second duration each, and the Geneva drive sorts that out for you.
I’d certainly never really thought or concerned myself over the inner workings of a tablet press machine, but who could dislike such a majestic Gif?
This is not a problem I have encountered. This is what Wikipedia has to say about it:
“A hypotrochoid is a roulette traced by a point attached to a circle of radius r rolling around the inside of a fixed circle of radius R, where the point is a distance d from the center of the interior circle.”
Or, if you’re more of an equations kind of person, try this:
Radial engines were commonly used in aircraft before turbine engines became more popular, but they’ve also been used in cars and tanks.
I actually have wondered about how sewing machines works before; and it’s like this…
I’ve learned some stuff today.
