Three-link Kinematic Chain: Generic Planar Mobility
Compare open and closed ideal three-link chains, counting ground as one link. Calculate nominal mobility and joint constraints without solving dimensions or motion.
Ten-bar Linkage: Nominal Planar Mobility Calculator
Explore a conceptual ten-link chain and calculate its nominal planar mobility from link and revolute-joint counts. Dimensions and motion paths are not solved.
Kinematic Chain: Four-Bar Animation and Mobility Count | FIRGELLI
Explore a fixed four-bar linkage and calculate the planar lower-pair count 3(n−1)−2j. Link and joint totals do not specify geometry or establish constraint independence.
