The vertebrae are irregularly shaped bones which stack together to form the spinal column. The
vertebrae are connected together by ligaments and muscles which control the degree of flexibility of the spine. The vertebrae are cushioned from each other by cartilage disks which act as shock absorbers to protect the vertebrae in the spine. The vertebrae may be separate (cervical, thoracic, and lumbar vertebrae), semi- articulated (as in some coccygeal vertebrae), or fused (as in the sacrum and coccyx). The typical vertebra has a body of solid bony material, which supports the weight of the spine, and an arch, which forms the vertebral foramen. It is the adjoining vertebral foramina which creates a canal down through the spinal column which houses and protects the spinal cord. The thoracic vertebrae feature facets to which the ribs attach, called costal facets.

The Carl Gustav M45 is a series of Swedish blowback operated, automatic sub-machine-guns first produced in 1945 and adopted as the standard weapon of the Swedish Armed Forces, and also sold to Egypt, Indonesia and Ireland. The guns are chambered for the 9 mm Parabellum cartridge and have a rate of fire of 600 rounds-per-minute with a muzzle velocity of 365 meters-per-second and an effective range of 200 meters. The original M45 took a Suomi 50-round box magazine, the B variant (Carl Gustav M45B) introduced in 1948 changed the magazine for a double-stack magazine with a capacity of 36-rounds which proved so reliable it has been widely copied in other weapons. The C variant has a bayonet lug and the E variant is selective single-shot or automatic. A silenced variant was also made and used by US Special Forces in South-East Asia.

The CZ101 is a variant of the CZ100 pistol, with a slimmer grip and a single stack magazine that reduces capacity to 7 rounds in the 9 mm Parabellum and 6 rounds in the .40 Smith and Wesson calibre.

The SIG P226 is a variant of the SIG P225 developed as a contender for the US Army's trials for a new combat pistol. The SIG P226 is chambered for the 9 mm Parabellum cartridge which it takes from a 15-round double-stack magazine.

The Spectre M-4 is an Italian double-action sub-machine-gun first produced in 1983. It is chambered for the 9 mm Parabellum cartridge which it takes from a four-stack 50-round box magazine and fires at a selectable rate of single shots or 850 rounds-per-minute automatic with a muzzle velocity of 400 meters per second.

A stack of arms is a number of rifles set up together, with the bayonets or barrels crossing one another, forming a sort of conical self-supporting pile.

The Dutch process (or stack process) was formerly the principal method by which white lead was prepared. It consisted building a stack of earthenware pots containing acetic acid upon a thick layer of spent tan or manure and placing strips or coils of metallic lead over the pots; boards were then laid to forma false floor over the whole and more stacks built on top. The entire structure was then sealed and over time the metallic lead converted into lead carbonate by corrosion caused by the action of the acetic acid vapour in the presence of carbon dioxide.

A magnetic disk is a flat circular disk coated with a magnetic material, used to store information in a computer system. The information is stored as a pattern of magnetised spots on the surface of the disk. The spots are arranged around the centre of the disk in concentric circles (tracks), which are divided into sectors. The disk is rotated in a disk drive, under a read/write head, which can both read the pattern of magnetised spots on the disk and write a pattern onto the disk. Several kinds of disk are in use. Some (fixed disks) are permanently fixed inside the disk drive, such as the Winchester disk used in small computers. Others, such as the floppy disk, can be removed from the disk drive. Large computers also use cartridge disks (in which the disks are held in a plastic cover) and disk packs (a stack of disks in a plastic hood).

In geography, a stack describes an isolated column close to the sea shore. In the erosion of cliff faces fragments are left separated from the rock face, and may be honeycombed with caves, and will ultimately disappear. The Needles off the west extremity of the Isle of Wight are a conspicuous example of stacks.
