Online puzzle Leg

A leg is a weight bearing and locomotive anatomical structure, usually having a columnar shape. During locomotion, legs function as "extensible struts". The combination of movements at all joints can be modeled as a single, linear element capable of changing length and rotating about an omnidirectional " hip " joint.

As an anatomical animal structure it is used for locomotion. The distal end is often modified to distribute force (such as a foot ). Most animals have an even number of legs.

As a component of furniture it is used for the economy of materials needed to provide the support for the useful surface, the table top or chair seat.
