A four bar linkage is a mechanical linkage that consists of four rigid bars or links connected by four joints to form a closed loop. The linkage ca...

Grashof's theorem states that in a four bar linkage, the sum of the shortest and longest link lengths should be less than or equal to the sum of th...

The four bar linkage can be classified into four types based on the arrangement of the links and the position of the input and output links. They a...

Four bar linkages provide smooth and efficient motion transfer between links, have a simple and compact design, and can be easily modified to adjus...

Four bar linkages have limited motion range and may not be suitable for applications that require more complex motion or high loads. The links and...
