TERMINOLOGY
• Machine
• Mechanism
• Kinematic chain
• Rigid body
Definition:Combination of resistant bodies so arranged that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinate motions
Definition:Assemblage of resistant bodies, connected by movable joints, to form a closed kinematic chain with one link fixed and having the purpose of transforming motion.Definition: When several links are movably connected together by joints, they are said to form kinematic chain. Definition:The parts connected to create kinematic chain are assumed to be rigid

Class 1 5
TERMINOLOGY
• Link
• Kinematic pair or joint
Definition:A Rigid body is called as link
Definition:Connection or joints between the links
