How to find Link Angles for a 4 Bar Linkage. 4 Bar Mechanism Link Angles are found using Law of Cosines and Law of Sines and a few geometry rules you may have forgotten. Bookmark my Machinery and Mechanisms Playlist: Β Β Β β’Β MachineryΒ andΒ MechanismsΒ Β This problem fits into your textbook in sections called Posture Analysis or Position Analysis. Four Bar Mechanism Theta 3 and Four Bar Mechanism Theta 4 are needed as the first step of the Loop Closure Method also called Vector Loop Method. It can also be used to find velocities by taking time derivative of position.
