The calculated constant tangential tolerance for this series gives (3 √ 10 − 1) ÷ (3 √ 10 + 1) = 36.60%, approximately. While the standard only specifies a tolerance greater than 20%, other sources indicate 40% or 50%.
For non-sequential numbers, like M1 Abrams, see bottom of list. M1 combat car, also known as the M1 light tank; M1 light motorcycle; M2 light tank, .5" MG or 37 mm gun, 11-ton
The mathematical constant e can be represented in a variety of ways as a real number.Since e is an irrational number (see proof that e is irrational), it cannot be represented as the quotient of two integers, but it can be represented as a continued fraction.
The 7.5 cm tornpjäs m/57 (75 mm turret gun model 1957) was developed for the Swedish Coastal Artillery in the 1950s as a light and comparatively cheap gun that would replace a large number of mostly obsolete systems for short-range coastal defense. Eventually, 30 three-gun batteries in three distinct series were built.
[3] [7] The 75 mm was then modified to include a larger caliber barrel, which was further developed into the 8.8 cm Flak 18/36/37/41, one of the best-known AA guns of World War II. [ 3 ] [ 8 ] Despite German unwillingness to buy the 75 mm variant, Bofors decided to start serial production anyway and the Bofors 75 mm Model 1929 proved an export ...
An infinite series of any rational function of can be reduced to a finite series of polygamma functions, by use of partial fraction decomposition, [8] as explained here. This fact can also be applied to finite series of rational functions, allowing the result to be computed in constant time even when the series contains a large number of terms.
The 7.5×55mm Swiss or 7,5mm GP 11 (or unofficially 7.5×55mm Schmidt–Rubin) is a cartridge developed for the Swiss Army.It originated from the Gewehrpatrone 1890 (7.5×53.5mm) developed in 1889 by mechanical engineer Lt. Col. Eduard Rubin for rifles based on Rudolf Schmidt's action design.
A further 10 were converted from 263 chassis in October 1942. This variant of the Sd.Kfz. series entered service during 1942 and remained in use throughout the war. They were issued as a platoon of six vehicles in support of reconnaissance battalions. The official name was Schwerer Panzerspähwagen (7,5 cm) Sd. Kfz. 233. Sd. Kfz. 263 (8-rad)
