Load can be transferred from a chain to another object by a chain stopper. Two distinct chains can be connected using a quick link, carabiner, shackle, or clevis. They are known as roller chains, though there are also non-roller chains such as block chain. Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension.Small chains serving as jewellery are a mostly decorative analogue of such types. Those designed for lifting, such as when used with a hoist for pulling or for securing, such as with a bicycle lock, have links that are torus shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length).Chains can be classified by their design, which can be dictated by their use: A chain may consist of two or more links.

As of the start of 1625, the Gregorian calendar was 10 days ahead of the Julian calendar, which remained in localized use until 1923.Ī chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. 1625 (MDCXXV) was a common year starting on Wednesday of the Gregorian calendar and a common year starting on Saturday of the Julian calendar, the 1625th year of the Common Era (CE) and Anno Domini (AD) designations, the 625th year of the 2nd millennium, the 25th year of the 17th century, and the 6th year of the 1620s decade.
