4bar is an educational software tool designed for the synthesis and design of planar four-bar mechanisms, slider-crank mechanisms, and Cardan mechanisms. Developed as a diploma thesis at Graz University of Technology, it provides interactive kinematic analysis features such as coupler curves, pole-curves, and transmission function optimization using the Hooke-Jeeves algorithm. The application serves as a pedagogical resource for students and professionals studying kinematic geometry.
