Definition and history of chains
A technical chain is a flexible assembly of connected pieces called links, mostly made of steel or other metals. Such products are generally used to handle mechanical loads or forces. The first appearance of chains in history books dates back about 4500 years, when they were used as gold and silver ornaments. Later on, chains made of copper, bronze, and iron were used to draw water buckets up from a well, hang up kettles, restrain prisoners and slaves, or fasten ship anchors.
