Chapter 5. Planar Linkages
Rocker: Any link which does not revolve is called a rocker. Crank-rocker mechanism: In a four bar linkage, if the shorter side link revolves and the other one rocks (i.e., oscillates), it is called a crank-rocker mechanism. Double-crank mechanism: In a four bar linkage, if both of the side links revolve, it is called a double-crank mechanism.
