dc.description.abstract	Mechanisms are means of Power Transmission as well as motion transformers. A Fourbar Mechanism consists mainly of four planar links connected with four revolute joints. Input usually given as rotary motion of a link and output can obtain from the motion of another link or a coupler point. Kinematic and Dynamic Analyses presented in this thesis. Path generation method has applied to generate planar four-bar mechanism. The task of analyses refers to a problem in which a coupler point desired to generate a given path. coupler point has traces a set of predefined points, the position of coupler point at each stage using analytical methods to approximate a linkage dimensions required to achieve a set of prescribed path points in order to study the Kinematic (velocity and acceleration) and Dynamic equation requirements and to satisfy the detailed steps in formulating the Planar four-bar mechanism solutions. MATLAB coding has written to find the solution of Velocity and Acceleration, and Dynamic force at various positon of the four bar mechanism producing by the linkages joints. Modelling of Planar Four-Bar Mechanisms is accomplished using the CATIA V5R21 in order to simplify the process and simulate the desired path is generated by coupler point. For the input example of predefined point PX & PY the coupler path point generated. velocity and acceleration graphs of the coupler point CATIA V5R21 and reaction force on the pin joints for prescribed input point has simulated with MATLAB R2016b. the coupler point can have used to generate prescribed points of practical applications.	en_US
