The 7.5 cm Feldkanone 16 neuer Art (7.5 cm FK 16 nA) was a field gun used by Germany in World War II.Originally built as the World War I-era 7.7 cm FK 16, surviving guns in German service were re-barrelled during the early 1930s in the new standard 7.5 cm calibre.
With respect to the extended Euler-Lagrange formulation (See Lagrangian mechanics § Extensions to include non-conservative forces), the Rayleigh dissipation function represents energy dissipation by nature. Therefore, energy is not conserved when . This is similar to the velocity dependent potential.
The most familiar non-contact force is gravity, which confers weight. [1] In contrast, a contact force is a force which acts on an object coming physically in contact with it. [1] All four known fundamental interactions are non-contact forces: [2] Gravity, the force of attraction that exists among all bodies that have mass. The force exerted on ...
The 7.5 cm Feldkanone 18 (7.5 cm FK 18) was a field gun used by Germany in World War II.It was designed to replace the 7.5 cm FK 16 nA, which was a World War I-era 7.7 cm FK 16 rebarreled in 75 mm during the early Thirties.
The 7.5 cm Pak 40 (7,5 cm Panzerabwehrkanone 40) was a German 75 millimetre anti-tank gun of the Second World War. The gun was developed in 1939–1941 and entered service in 1942. With 23,303 examples produced, the Pak 40 formed the backbone of German anti-tank guns for the later part of World War II, mostly in towed form, but also on a number ...
The 7.5 cm Infanteriegeschütz 37 (7.5 cm IG 37) was an infantry support gun, used by Germany during World War II.The guns were originally designated 7.5 cm PaK 37.The IG 37s were manufactured from carriages of 3.7 cm Pak 36s (and the nearly identical Soviet 3.7 cm PaK 158(r)) and a barrel designed originally for the IG 42 infantry support gun.
The 7.5 cm Pak 41 was one of the last German anti-tank guns brought into service and used in World War II and notable for being one of the largest anti-tank guns to rely on the Gerlich principle (pioneered by the German gun-designer Hermann Gerlich, who developed the principle in the 1920s, reportedly for a hunting rifle) to deliver a higher muzzle velocity and therefore greater penetration in ...
7.5 cm Pak 39 (L/48) (7.5 cm Panzerjägerkanone 39) was a 7.5 cm German Second World War era anti-tank gun.The gun was used to equip Jagdpanzer IV/48 and Jagdpanzer 38 tank destroyers; [1] no towed version of the weapon was made.
