Don't pull my chain started when people's wallet chains were being pulled, and it bothered them so much.
The business terms push and pull originated in logistic and supply chain management, but are also widely used in marketing. Wal-Mart is an example of a company that uses the push vs. pull strategy. A push–pull system in business describes the movement of a product or information between two subjects. On markets the consumers usually "pull" the goods or information they demand for their needs, while the offerers or suppliers "pushes" them toward the consumers. In logistic chains or supply chains the stages are operating normally both in push- and pull-manner. Push production is based on forecast demand and pull production is based on actual or consumed demand. The interface between these stages is called the push–pull boundary or decoupling point.
A push strategy within the advertising/marketing industry involves directing marketing efforts at resellers. The success of the marketing depends on the ability of these intermediaries to market the product. The goal of a push strategy is to make the customer aware of the product/brand at the point of purchase. Examples of push strategy tactics include displaying the product near the register, a packaging design to encourage purchase, and direct selling to customers at stores.
A jack chain is a type of chain made of thin wire, with figure-eight-shaped links, and loops at right angles to each other. Jack chains are often used to suspend fixtures such as lights or signs, for decorative purposes, or as part of a cable lock.
Jack chain may be manufactured as either single-jack chain or as double-jack chain. If double-jack, the lower loop is formed of two strands of wire rather than just one as in a single-jack.
A chain weapon is a weapon made of one or more heavy objects attached to a chain, sometimes with a handle. The flail was one of the more common types of chain weapons associated with medieval Europe, although some flails used hinges instead of chains.
There were several chain weapons that were used in feudal Japan; these weapons were allegedly used by the ninja. The shoge was a ring with a sickle-like knife on a chain that could be used to pierce armor, grapple, and to entangle the legs of man and horse. The kusari-gama was a kama on a handled chain. The chigriki was a staff with a weighted chain on the end. The manriki-gusari was a double weighted chain. The nunchaku was a short chain with two short wooden sticks on the ends. The nunchaku is often thought of as a feudal weapon. It was used in those times for farming and not as a weapon until much later.
Flat chain is a form of chain used chiefly in agricultural machinery. Early machinery made extensive use of flat chain. It has been gradually replaced in most applications by roller chain, which is quieter, lasts longer, and requires less frequent retensioning.
Modern flat chain is made from stamped steel. Individual links can be put together or taken apart using simple tools, unlike roller chain which requires a master link or special splicing equipment.
A pull switch is a switch that is actuated by means of a chain or string.
An electric pull switch is attached to a toggle type switch: one pull to switch on and next pull to switch off.

An omega chain or omega necklace is a pseudo-chain made by assembling metallic plates on a wire or woven mesh. The plates give the appearance of links in a chain. The embedded wire provides the strength, so the plates can be designed to please the eye.
The business terms push and pull originated in the logistic and supply chain management, but are also widely used in marketing.

Mechanical engineering is a discipline of engineering that applies the principles of engineering, physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines.
The engineering field requires an understanding of core concepts including mechanics, kinematics, thermodynamics, materials science, structural analysis, and electricity. Mechanical engineers use these core principles along with tools like computer-aided engineering, and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others.
A wallet, or billfold, is a small, flat case that is used to carry personal items such as cash, credit cards, identification documents (driver's license, identification card, club card, etc.), photographs, gift cards, business cards and other paper or laminated cards. Wallets are generally made of leather or fabrics, and they are usually pocket-sized but not always foldable.
The word "wallet" has been in use since the late fourteenth century to refer to a bag or a knapsack for carrying articles. The word may derive from Proto-Germanic. The ancient Greek word kibisis, said to describe the sack carried by the god Hermes and the sack in which the mythical hero Perseus carried the decapitated head of the monster Medusa, has been typically translated as "wallet". Usage of the term "wallet" in its modern meaning of "flat case for carrying paper currency" in American English dates to 1834 but this meaning was one of many in the 19th century and early 20th century.
