Volume 1
Foreword Who is going to read this book of Metromeccanica should know that may not be a manual of Metromeccanica. Because this science, in 1991, does not exist. In other words: start now to exist as born with this book, and the first inventions which the author wanted to give this adjective, to understand a new type of mechanical absolutely different from traditional and whose general principles will be phased in limits of what the author knows when, as set out below. Who is going to read this book, which is not distributed as other books, must feel committed (because, if you are reading,you can) to continue on the path that starts here, discovering,realizing or disseminating what may arise from this new science. It is not the intention of the author, who knows his limitations,write volumes except the first.
CHAPTER 1 First Principle of Metromeccanica In the absence of other principles, this is the first. If someone readers will think something more is valid willing to grant this record, but I do not think that this one merits less than second place. "A mechanism metromeccanico must carry out what which it was created " Since "things" that the first did not exist I do not think the term "created" excessive. However goes well "designed". First, this means completely distorting the view habitual; Think about the impact to create the cause overturning the conventional mechanical. And as you will see below this may prove useful. In traditional mechanics (which according to the author fails to away from the well-known medieval roots) a mechanism can to reach its goal in any way. And, if not satisfactorily reached, it is reasonable to add another mechanism that "correct the route." And, if this is not enough, it is very likely that if they add another. And so forth. We arrived at 1991 continuing to put "pieces" on inventions now should be forgotten for a long time. Computers seemed to many people the right solution to solve problems but succeeded only in creating new pieces, so sophisticated be able to hide the almost goofy mechanism original. The author states that there is, in this moment, on a computer and, usually, it uses other three; it is far from deny their usefulness. The problem is: if I have to reach Venice from Milan, I go to the east or west? One solution is: if I go by foot to the west I put more time that going by air to the east. The mechanics of 1991 using a plane that circumnavigate the globe,Metromeccanica suggests to go west with another vehicle that not feet. (The airplane is fine). By delegating the solution of the problems of a mechanical obsolete we accepted the limits that we set ourselves in providing directions to elaborate. A servomechanism that is programmed to solve a fifty different conditions, as the fifty-first to react? And you can be assured that the fifty-first occurs. A mechanism metromeccanico, therefore, must create autonomously provided what they is designed: if it is a brake, his condition normal is to be slowed (and the abnormal is to be free) if it is a change of speed its normal condition is to be "overdrive "(abnormal is to be" the first gear "), if a spacecraft his condition is normal to be in space (the abnormal is to be on the launching pad), and so forth. About: * Little Problem * for the N.A.S.A. To put into orbit the "Columbia" requires X tonnes of Fuel;
* * Question: How many fuel tanks will be needed to put orbiting the "Columbia" and everything else? * * Answer: Three. But very big.
CHAPTER TWO According to the principle of Metromeccanica That is the same premise of the first. "A mechanism metromeccanico must aim, both in design that execution at maximum simplicity " According to the author, this principle is equally valid in the first, The search for half simple (and effective) to solve a problem "metromeccanico" often leads the researcher track to "invent" a valid device metromeccanico. Optimizing the number of components in a mechanism metromeccanico means, as well as reduce the cost of its implementation, reduce unnecessary friction and allow the forces involved to carry out their "Assets" without wasting energy. Thick the genius is in agreement with simplicity. If the idea is brilliant, we must not charge it with superstructures unnecessary. And if the superstructures are useful, it may mean that the idea of departure was not brilliant. Some information needed to understand this was the second chapter already in the first; Others will follow in later chapters. About: * Little Problem * for a manufacturer of automatic Change. An automatic 4-speed transmission is already almost a meter long, Question: How does that work? Answer: it is half meters long moreover, can the fingers thatbuilding the car to move further everything possible (Including the driver, if necessary) and, most importantly, it calls with a name that sounds good. And seems intelligent.
CHAPTER THREE Third principle of Metromeccanica Apply the usual premises. "A mechanism metromeccanico must strive for total absence of frictions " I tend said, I do not pretend a "perpetual motion" (but ...). - All tend to reduce friction- will laughin somehow distracted. Then axplain me what we are to do, in 1991, those ridiculous brakes that fitted our cars. With double circuit, with the ABS, self discs, carbide something ... But is always the same ridiculous mechanisms that few centuries ago (indeed, some millennium ago) was breaking the wheels of carts. The difference? Well, apart from the horse, which contributed enough to braking, has not changed much. As already mentioned, superstructures, servomechanisms, electronic equipment, but the problem centuries ago remains intact: hard fearful, overheating, deformation of the elements, wear materials etc.. Yet there are many ways to slow motion, but to combat it, without having to resort to the most trivial and archaic of all the frictions. The metromeccanica suggests that a "brake" is in its condition optimal, slowed. So, to design a brake metromeccanico (already), just as usual overthrow the problem: And the axis slows. I seemed the most important problem, relative to the third principle of metromeccanica. About: Little Problem for manufacturers of motor vehicles. (I do not make names for not me enemy some reader). A car goes a long descent with heavy use of brakes ( the driver is a bit distracted) and the brake oil goes into boiling. * * Question: When the driver realizes that the brake pedal less useful is that of the holy on the dashboard and that the "hand brake" not manages that to maintain constant speed (which detects when the little problem is already considerably high) what it does? (N.d.r. the problem is autobiographic) * * Answer: Find an open field where landing after takeoff from the next curve. (The author preferred the holy and it is here in write) * * Or: Open the door and tries to slow with the heel of shoe (which is still a valid friction).
CHAPTER FOUR Fourth principle of Metromeccanica. "To fully understand the metromeccanica need to be understood perfectly its three basic principles " Especially the essentiality. Therefore, in the opinion of the author, not serve others. Franco Scopinich Btw: not judge the Metromeccanica according to my bad English |
