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:

Nail (relic)

Relics that are claimed to be the Holy Nails with which Christ was crucified are objects of veneration among some Christians, i.e., among Catholics and the Eastern Orthodox. In Christian symbolism and art they figure among the Instruments of the Passion or Arma Christi, the objects associated with Jesus' Passion. Like the other Instruments the Holy Nails have become an object of veneration among many Christians and have been pictured in paintings and supposedly recovered.

When Helena, mother of Constantine the Great discovered the True Cross in Jerusalem, the legend was told by and repeated by Sozomen and Theodoret that the Holy Nails had been recovered too. Helena left all but a few fragments of the Cross in the Basilica of the Holy Sepulchre in Jerusalem, but returned with the nails to Constantinople. As Theodoret tells it in his Ecclesiastical History, chapter xvii,

The mother of the emperor, on learning the accomplishment of her desire, gave orders that a portion of the nails should be inserted in the royal helmet, in order that the head of her son might be preserved from the darts of his enemies. The other portion of the nails she ordered to be formed into the bridle of his horse, not only to ensure the safety of the emperor, but also to fulfil an ancient prophecy; for long before Zechariah, the prophet, had predicted that 'There shall be upon the bridles of the horses Holiness unto the Lord Almighty.

Inertia

Inertia is the resistance of any physical object to any change in its state of motion (this includes changes to its speed, direction or state of rest). It is the tendency of objects to keep moving in a straight line at constant velocity. The principle of inertia is one of the fundamental principles of classical physics that are used to describe the motion of objects and how they are affected by applied forces. Inertia comes from the Latin word, iners, meaning idle, sluggish. Inertia is one of the primary manifestations of mass, which is a quantitative property of physical systems. Isaac Newton defined inertia as his first law in his Philosophiæ Naturalis Principia Mathematica, which states:

In common usage, the term "inertia" may refer to an object's "amount of resistance to change in velocity" (which is quantified by its mass), or sometimes to its momentum, depending on the context. The term "inertia" is more properly understood as shorthand for "the principle of inertia" as described by Newton in his First Law of Motion: that an object not subject to any net external force moves at a constant velocity. Thus, an object will continue moving at its current velocity until some force causes its speed or direction to change.

Inertia (Derek Sherinian album)

Inertia is the second studio album by keyboardist Derek Sherinian, released in 2001 through InsideOut Music. This album marks the beginning of Sherinian's longtime collaborations with drummer Simon Phillips as well as guitarists Steve Lukather and Zakk Wylde.
