Linkage, an Uncommon card

The card carries these facts from its Wikipedia article.

• The movement of a body, or link, is studied using geometry so the link is considered to be rigid.
• The connections between links are modeled as providing ideal movement, pure rotation or sliding for example, and are called joints.
• A linkage modeled as a network of rigid links and ideal joints is called a kinematic chain.
