A topic dealt with too often academically quickly, but that I think deserves more attention, and some more practical consideration is that the treatment of the so-called "SIMPLE MACHINES . Actually, from Archimedes to Leonardo coming to this day often is to use these machines without knowing farlo.Chi of us have never used a nutcracker? Who has never been to the dentist? Who has not seen lifting a car with a crick?
Indeed, although initially the simple machines were born for war purposes today, some of them allow us to solve a series of problems with the application of forces to execute small claims such as lifting and / or movements of considerable loads. Sure enough
sometimes be a little 'more power "but believe the invention of simple machines help us to deal with" less work "of everyday life.
