Problems: Determine the kinematic chain#

In practice, we must first determine the kinematic chain of a real mechanism before doing any analysis. The process consists of abstracting the real object into a kinematic diagram (or schematic), which is a simplified representation. In this diagram, links are drawn as simple lines or polygons, and joints are represented with standardized symbols (a circle for a revolute joint, a block on a guide for a slider, etc.). This step is crucial to be able to apply the formulas and analysis methods.
