The mechanical principles are not very hard to explain and to understand, but there are people that cannot put in their heads what they are seeing and what is going on. When they don’t want to understand than what is the point of explaining the principles to them. We have one brilliant video made by the famous photographer and documentary maker Ralph Steiner.

Sometimes we are seeing mechanical parts moving in a machine and we try to identify what a particular part is doing. It is good to try and to decode every part and to know the purpose and the point of being there. That is how logic was born and that is how machines are made. Using the mechanical principles there are simple machines made that work like robots. When actually there are few parts that are moving all the time but their shape and with the help of some springs the parts combine and make the machine. Then the machine with the simple parts that are moving all the time is producing something. Now that is mechanical engineering that has been done for years and hasn’t changed a lot since beginning. Even back in the days when there were no cars and no electricity the people understood mechanics and they used the water in the rivers to make the watermills. That is also a mechanical principle that is used in order to do good for humanity.

The wrist watch that you are wearing right now has too many moving parts inside and they all have one purpose – to keep time. There are gears inside and shafts that all move but because of their shape they change the movement from continuous to step moving. Step moving is done with a small pause, like the one second pause on the wrist watch.

In this video there are great mechanical principles explained that will train your brain a little more.
