ABSTRACT
Four bar linkages are the most basic and most widely used mechanisms for machine design. They provide simple solutions to the complex motion generation problems. These mechanisms are reliable and at the same time easy to manufacture. There are infinite synthesis problems. The common classes of problems with practical importance and developed are : The Point Path Problem (Watt suspension linkage, Peaucelier linkage),The Function Generation Problem (mathematical function, Bourlet linkage), The problem of Force Amplification (Mechanical advantage of the four bar linkage).

INTRODUCTION
The articulated quadrilateral and articulated systems in general have countless applications in all sectors of industry: machine tools, automotive, aviation, agriculture, robotics, medicine... Applications can be grouped into four families:
the mechanism that allows a point to describe an algebraic curve ;
the mechanism enabling the exact realization of a given function;
the mechanism for approximating a given function;
the mechanism that amplifies mechanical actions.
For each group, detailed methods are given to lead the reader through to practical applications, as the developments can be complex. The results have always been formulated using readily available computational tools (MAPLE, MATLAB...), making them easy to exploit.
