Notes_01_01 1 of 8 Definitions Kinematics – the study of constrained motion without regard to forces that cause that motion Dynamics – the study of how forces cause motion Causality – the relationship between cause and effect Degrees-of-freedom (DOF) of motion – specific ways in which a rigid body or mechanical system may move Kinematic joint – a connection between two rigid bodies that restricts specific DOF of motion in a reproducible manner Dyad (kinematic pair) – a pair of rigid bodies connected by a kinematic joint Kinematic chain (loop) – a sequence of dyads Link – a rigid body in a kinematic chain Binary link – a link with two joint connections Ternary link - a link with three joint connections Open kinematic chain (loop) – one that does not close back onto itself Closed kinematic chain (loop) – one that does close back onto itself Mechanism - a kinematic chain designed to transfer motion but not a significant amount of power Machine - a kinematic chain designed to transfer power Skeletal diagram – a succinct schematic drawing of a kinematic chain Topology – connectivity analysis of a chain without regard to geometry Mobility – DOF for a mechanism Instant center - unique point at which two objects in general planar motion have the same velocity
