A chain is a series of connected links. This article is about the literal, physical chain. A chain may consist of two or more links.

A chain is usually made of metal.

Chains are usually made in one of two styles, according to their intended use:

  • 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 makes the chain flexible in two dimensions (The fixed third dimension being a chain's length.)
  • 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. They are known as Roller chains, though there are also non-roller chains such as block chain.

Are there any nationwide chains that do home remodeling?
Q. My wife and I want to completely renovate two bathrooms in a home we are purchasing. There are just too many local choices to choose from. Are there any nationwide chains out there? In particular, ones that offer financing?
Asked by russ_0067 - Tue Aug 21 08:40:27 2007 - - 2 Answers - 0 Comments

A. Nationwide chains hire local contractors to do the work. You are paying a "middleman" fee for using them.

How long do you usually have to wear power chains for?
Q. I have had braces since August 25th of this year. For the last couple of visits so for the past 10 weeks i have had to wear power chains. Last time i could not choose colors because they didn't have a power chain in any color but purple that would fit my upper teeth and braces. I had 4 teeth plus 4 wisdom teeth pulled in August. So why do i need power chains this early? And if you had them how long did you have to wear them for?

A. They are trying to get the teeth to move together. Now is the time, why would you want the teeth to get settled in the wrong positions? Having your wisdom teeth pulled doesn't really have any effect on your ortho, its just nice to get them out of the way while you were having the other surgery done.

What are the functions of the protein chains in hemoglobin?
Q. So heme if the carrier of gases, so what do the chains do?
Asked by some guy - Sun May 4 23:05:26 2008 - - 2 Answers - 0 Comments

A. Greetings, The heme (iron) binds the Oxygen, CO2, and if you're unlucky or a smoker, the Carbon Monoxide. The main function of the rest of the proteins is simply to exist in such a state as to allow the heme to properly bind to the proper gases depending on the current location of the RBC. The chains, 2 alpha and 2 beta, morph and twist themselves around a molecule from the Embden-Meyerhof pathway in the mature RBC, 2,3-DPG. This 2,3-DPG molecule becomes assoicated with a molecule of hemoglobin with changes in the shape of the globulin chains. It is the 2,3-DPG molecule that determines the hemoglobins' affinity for O2. When your RBC reaches your O2 depleted body part, the heme molecule drops off the O2, and when the chains pulls… [cont.]
