"WebIn a four-bar mechanism we can have the following three different types of motion: i) Both of the links connected to the fixed link can have a full rotation. This type of four-bar is called " double-crank " or " drag-link ". ii) Both of the links connected to the fixed link can only oscillate. This type of four-bar is called “ double-rocker ."
