What is the Meaning & Definition of mechanisms

He is designated with the term of mechanism that set of elements, mostly rigid, having as raison d ' être transmit or start a movement.
Between fundamental and characteristic of a mechanism components we find the following: link, which is the rigid element that serves for the transmission of the movement which will lead to the operation of the mechanism in question; the node, that element of a link that is used to link to another link and the Board or torque servo, which is the element that indicates the union of two or more links.
On the other hand, the links involved in a mechanism can be classified according to the number of nodes that have binary, ternary or Quaternary, depending on the function that deployed in fixed, driver, transducer and driven and according to the movement resulting in fixed, crank, crank and slider.
Each of these nodes mentioned above, meanwhile, have different movements. For example, crank has a rotary motion, the slide will make the movement that is known as translation, the crank will represent the movement's general plan, the driver, will be that everyone will start the movement, the led that receives the motion of the conductor and the transducer that has the mission to inform driver with led. Among the examples of the most common mechanisms and with which we can face regularly, we can mention that exercise the wiper of a car, the movement of back and forth to remove water from the surface of the glass of a vehicle, is achieved thanks to the design of a mechanism as which describe more above.
In a quite opposite path and that it has nothing to do with what you were discussing, are defense mechanisms, which have a special significance and importance in the field of psychology that defined them as those cognitive operations that persons deployed at one time to defend themselves from any issue or hazard that it threatens them.
For example, a person who suffered diverse and followed loving deceptions once became involved in a romantic relationship, surely, the next time that this at the prospect of getting involved with someone, will unconsciously, tend to boycott the relationship never to suffer again through different actions.
