Find Out How Things Work Through The Medium Of GIFs

On June 23, 2013 by Tim Newman


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:

How A Geneva Drive Works

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?

How To Draw A Hypotrocoid

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:

Hypotrochoic Equations 21Or, you can ignore all of that and enjoy the pleasing simplicity of a GIF in full swing:
