    A direct link is when an object’s parts are held together without assistance, and there is no connecting member between them. When there is a connecting member (ex: screw, nail, or glue), the link is indirect.

    A rigid link does not allow for any variation in the position of the parts it binds. The member that connects the parts is rigid, like strong glue. Conversely, an elastic link involves a connecting member that allows for variation in the position of the parts it binds, such as a spring. It is thus possible to modify the position of the parts relative to each other and to make parts return to their initial position.
