Lever
A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or ''fulcrum''. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. Also, leverage is mechanical advantage gained in a system. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English around 1300 from Old French, in which the word was ''levier''. This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to the Latin ''levare'', itself from the adjective ''levis'', meaning "light" (as in "not heavy"). The ...

The Lever (song)
''Diorama'' is the fourth studio album by Australian alternative rock band Silverchair, released on 31 March 2002 by Atlantic/Eleven. It won the 2002 ARIA Music Award for Best Group and Best Rock Album. The album was co-produced by Daniel Johns and David Bottrill. While Bottrill had worked on albums for a variety of other bands, ''Diorama'' marked the first production credit for lead singer Johns. Johns wrote most of the album at the piano instead of his usual guitar, while the band took a 12-month break following their previous studio album, ''Neon Ballroom''. Silverchair worked with composer Van Dyke Parks on ''Diorama''; the album contains numerous orchestral arrangements and power ballads, a change from the grunge music typical of their earlier work, but consistent with the band's previous orchestrations on ''Neon Ballroom''. The album's title refers to "a world within a world". Four singles were released: " The Greatest View", " Without You", "Luv Your Life", "Across ...

Lever-action
The toggle-link action used in the iconic Winchester Model 1873 rifle, one of the most famous lever-action firearms Lever-action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area (often incorporating it) that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, or automatic/selective-fire actions. A firearm using this operating mechanism is colloquially referred to as a levergun. Most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have been made. The Winchester Model 1873 rifle is one of the most famous lever-action firearms, but many manufacturers (notably Henry and Marlin) also produce lever-action rifles. Even Colt's Mfg. Co. produced the 6403 lever-action ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firearm Action
In firearms terminology, an action is the functional mechanism of a breech-loading firearm that handles (loads, locks, fires, extracts and ejects) the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the ''lock'' (e.g. matchlock, flintlock, caplock). Actions can be categorized in several ways, including single action versus double action, break action versus bolt action, and others. The term action can also include short, long, and magnum if it is in reference to the length of the rifle's receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of or smaller. The long action rifle can accommodate a cartridge of , and the magnum action rifle can accommodate cartridges ...
