A cable tie (also known as a hose tie, panduit [1], tie wrap, wire tie, zap-straps, or zip tie) is a type of fastener for holding items together, primarily electrical cables and wires. Because of their low cost, ease of use, and binding strength, cable ties are ubiquitous, finding use in a wide range of other applications.
The lightweight 16-in/50 Mark 7 was designed to resolve this conflict. These guns were 50 calibers long, 50 times their 16-inch (406 mm) bore diameter with barrels 66.7 ft (20.3 m) long, from chamber to muzzle. Each gun weighed about 239,000 lb (108 t) without the breech, and 267,900 lb (121.5 t) with the breech. [1]
A hurricane tie used to fasten a rafter to a stud. A tie, strap, tie rod, eyebar, guy-wire, suspension cables, or wire ropes, are examples of linear structural components designed to resist tension. [1] It is the opposite of a strut or column, which is designed to resist compression. Ties may be made of any tension resisting material.

[ 5 ] [ 6 ] The second Navy design, the Mark 2, was intended as armament for the planned South Dakota -class battleships , and also selected for the modified design of the Lexington -class battlecruisers ...
A gun serial number is a unique identifier assigned to a singular firearm. [A] There is no international uniformity in gun serial numbers. Besides a widespread numerical base, they may contain letters and other typographical symbols, or may consist entirely of a character string; positioning and form of such identifiers is idiosyncratic.

Today, microprocessor-based relays can perform many protective functions in one device. [1] When one device performs several protective functions, it is typically denoted "11" by the standard as a "Multifunction Device", but ANSI Device Numbers are still used in documentation like single-line diagrams or schematics to indicate which specific ...
The ammunition handling system has two conveyor belt systems. The first takes the rounds out of the magazine drum to the gun; the second takes empty shells or unfired rounds to the opposite end of the drum. The 20 mm APDS rounds consist of a 15 mm (0.59 in) penetrator encased in a plastic sabot and a lightweight metal pusher. [16]
The U.S. Navy had the 16"/50-caliber Mark 2 guns left over from the canceled Lexington-class battlecruisers and South Dakota-class battleships of the early 1920s. However it was already apparent that the Mark 2 was too heavy to arm the North Carolina and new South Dakota (1939) battleship classes which had to adhere to the 35,000 ton standard displacement set by the Second London Naval Treaty.
