Nail (unit)

A nail, as a unit of cloth measurement, is generally a sixteenth of a yard or 2¹⁄₄ inches (5.715 cm). The nail was apparently named after the practice of hammering brass nails into the counter at shops where cloth was sold. On the other hand, R D Connor, in The weights and measures of England (p 84) states that the nail was the 16th part of a Roman foot, i.e., digitus or finger, although he provides no reference to support this.Zupko's A dictionary of weights and measures for the British Isles (p 256) states that the nail was originally the distance from the thumbnail to the joint at the base of the thumb, or alternately, from the end of the middle finger to the second joint.

An archaic usage of the term nail is as a sixteenth of a (long) hundredweight for mass, or 1 clove of 7 pound avoirdupois (3.175 kg).

The nail in literature

Thou yard, three-quarters, half-yard, quarter, nail
Thou flea, thou nit, thou winter cricket thou:―
Brav'd in mine own house with a skein of
thread!

Explanation: Katherine and Petruchio are getting married. At the tailor shop, they examine the wedding dress, which is nearly finished. Petruchio is concerned that it has too many frills, wonders what it will cost, and suspects that he has been cheated. Katherine says she likes it, and complains that Petruchio is making a fool of her. The taylor repeats Katherine's words: Sir, she says you're making a fool of her. This is where Petruchio launches into the above-quoted tirade. Monstrous may be a double-entendre for cuckold. The half-yard, quarter and nail were divisions of the yard used in cloth measurement.

Nail (fastener)

In woodworking and construction, a nail is a pin-shaped object of metal (or wood, called a treenail or "trunnel") which is used as a fastener, as a peg to hang something, or sometimes as a decoration. Generally nails have a sharp point on one end and a flattened head on the other, but headless nails are available. Nails are made in a great variety of forms for specialized purposes. The most common is a wire nail. Other types of nails include pins, tacks, brads, and spikes.

Nails are typically driven into the workpiece by a hammer, a pneumatic nail gun, or a small explosive charge or primer. A nail holds materials together by friction in the axial direction and shear strength laterally. The point of the nail is also sometimes bent over or clinched after driving to prevent pulling out.

History

The history of the nail is divided roughly into three distinct periods:

Elasticity (economics)

In economics, elasticity is the measurement of how responsive an economic variable is to a change in another. It gives answers to questions such as:

An elastic variable (with elasticity value greater than 1) is one which responds more than proportionally to changes in other variables. In contrast, an inelastic variable (with elasticity value less than 1) is one which changes less than proportionally in response to changes in other variables. A variable can have different values of its elasticity at different starting points: for example, the quantity of a good supplied by producers might be elastic at low prices but inelastic at higher prices, so that a rise from an initially low price might bring on a more-than-proportionate increase in quantity supplied while a rise from an initially high price might bring on a less-than-proportionate rise in quantity supplied.
