Effective supply of ammunition and replacement parts was an almost insoluble task and the army decided to adopt a standard machine gun. The result was the AA-52, conceived for ease of production. The construction is of simple welded stamped sheet steel. The AA-52 was partially withdrawn from the service of the French army in 2008.
Flat belt on a belt pulley Belt and pulley system Cone pulley driven from above by a line shaft. A belt and pulley system is characterized by two or more pulleys in common to a belt. This allows for mechanical power, torque, and speed to be transmitted across axles. If the pulleys are of differing diameters, a mechanical advantage is realized.
Since the 1980s, the standard procedure used to solve the problem of deformed belts was to turn the belt over, i.e. what was previously the back of the belt was used to form the new product side. [citation needed] The belt became flatter when turned due to the equalization of stresses on both sides. However, over time, the belt typically ...
Serpentine belt (foreground) and dual vee belt (background) on a bus engine Belt tensioner providing pressure against the back of a serpentine belt in an automobile engine. A serpentine belt (or drive belt [1]) is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air ...

Orion's Belt is an asterism in the constellation of Orion. Other names include the Belt of Orion , the Three Kings , and the Three Sisters . [ 1 ] The belt consists of three bright and easily identifiable collinear star systems – Alnitak , Alnilam , and Mintaka – nearly equally spaced in a line, spanning an angular size of ~ 140 ′ (2.3°).
On 25 December 2021, VA256 launched the James Webb Space Telescope towards a Sun–Earth L 2 halo orbit. [52] The precision of trajectory following launch led to fuel savings credited with potentially doubling the lifetime of the telescope by leaving more hydrazine propellant on board for station-keeping than was expected.
