A mechanism is needed to keep the two legs bones attached to each other, while still allowing rotation. In the case of the human knee this is achieved with a four-bar linkage consisting of the two bones together with the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL), as shown below.

I've always been fascinated by mechanisms that use some kind of geometric 'trick' to accomplish a task. A prime example of such a mechanism are toggle clamps. While there are many designs one can find for toggle clamps, the basic operational principle tends to be the same in most cases. Pin connections and two force members

Double-crank mechanism: In a four bar linkage, if both of the side links revolve, it is called a double-crank mechanism. Double-rocker mechanism: In a four bar linkage, if both of the side links rock, it is called a double-rocker mechanism. 5.2.3 Classification. Before classifying four-bar linkages, we need to introduce some basic nomenclature.

Linkage mechanisms consist of a series of mechanical linkages that can change direction, alter force and make things move in a certain way. We use linkage mechanisms in a number of different systems and also in machinery. Linkage mechanisms give you the ability to take one kind of motion and turn it into another type.
