A mechanism is a set of parts or devices that allow us to carry out work, that is, to transmit or transform a movement.
It seems that in the age of electronics you have gone to the background, but its importance is still vital, since any creation that has to be brought to the physical plane will need mechanisms, no matter how basic they are.
Mechanisms have been studied since ancient times and they continue to be and will be one of the necessary parts in your facet as an inventor.
Engineering, mechatronics, robotics need mechanisms. How many more do you know and understand how physical laws work, what they are for and how they act, more variety of options and new mechanisms adapted to your project will you be able to create.
A lever is a mechanism, a cam, an Archimedean screw. We are going to enter a really interesting world. And they are not only useful for inventions, makers, artists, and many other creative guilds need to know about them even if they have not realized it yet.
The first thing to thank the people of Twitter that has helped me in the translation of the title Trammel of Archimedes, which in the end has remained as Archimedean Compass. We have shuffled «Archimedean trammel» and another approach «Archimedean Lattice».
We have seen Clepsydras, Eolipilla or Aeolus of Heron, but we had not yet seen the Heron's Fountain which is a hydraulic machine created by Heron of Alexandria (XNUMXst century physicist, mathematician and engineer) An all-time classic of the fluid dynamics.
The oldest version, that of Heron, was as follows.
The operation is very simple.
The water is falling from A to C (filled with air and airtight) and pushes the air in C towards B (filled with water), which pushes the water towards A.
Well in the image we have a series of valves that are useful to us to initialize our process, although as you will see it can be done much more at home.
According to the picture. Initially we have the three valves closed and we add water in A. We open V2 and tank B will be filled and opening V3 will bring it to atmospheric pressure. We close the two valves and open V1 for the source to start working.
