M4 Sherman Variants
The M4 Sherman tank was produced in several variants, a result of mass production spread across several manufacturers and several years. It was also the basis for a number of related vehicles and Shermans have been modified by several nations, ranging from upgrades to complete hull conversions for another task. Originally designed in 1941, M4 variants were still used by Israel during the 1967 and 1973 wars with its Arab neighbors. The many special duties that a tank might be made to do were just being explored by armies around the world in the early 1940s. Theories of what vehicles were supposed to be engaging enemy tanks changed as vehicles like the Sherman often found themselves up against enemy armor, and consequently some of the most important initial changes centered around up-gunning the basic vehicle. Improving the vehicle's mobility, protection, and creating specific variants for infantry-support roles soon followed. Similar modification of the main armament would be done ...

M4 Sherman
} The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman evolved from the M3 Medium Tank, which for speed of development had its main armament in a side sponson mount. The M4 retained much of the previous mechanical design, but moved the main 75 mm gun into a fully traversing central turret. One feature, a one-axis gyrostabilizer, was not precise enough to allow firing when moving but did help keep the gun aimed in rou ...

M4A2 Sherman, Kyiv
Single-payer healthcare is a type of universal healthcare in which the costs of essential healthcare for all residents are covered by a single public system (hence "single-payer"). Single-payer systems may contract for healthcare services from private organizations (as is the case in Canada) or may own and employ healthcare resources and personnel (as is the case in the United Kingdom). "Single-payer" describes the mechanism by which healthcare is paid for by a single public authority, not a private authority, nor a mix of both. Description Within single-payer healthcare systems, a single government or government-related source pays for all covered healthcare services.Medical Subject Headings thesaurus, National Library of Medicin"Single-Payer System" Year introduced: 1996, (From Slee and Slee, Health Care Reform Terms, 1993, p. 106) Governments use this strategy to achieve several goals, including universal healthcare, decreased economic burden of health care, and improved hea ...

Chrysler A57 Multibank
The Chrysler A57 Multibank is a 30-cylinder engine that was created in 1941 as America entered World War II. It consists of five banks of inline-6 cylinder engines. It was born out of the necessity for a rear-mounted tank engine to be developed and produced in the shortest time possible for use in the M3A4 Lee medium tank and its successor M4A4 Sherman medium tank. Each had lengthened hulls to accommodate the A57. In order to use existing tooling, five Chrysler flathead engines (bore , stroke ) were arranged around a central shaft, producing a unique 30-cylinder engine in a relatively compact but heavy package. The combined assembly consisted of five of these straight-six engines mounted in a pseudo-radial fashion upon a central cast-iron crankcase. The arrangement employed a common radiator, water pump, oil pan & dual oil pumps, with each of the five component crankshafts fitted with a geared flywheel that meshed with a central sun gear that drove a main shaft running thr ...

Vietnam War
The Vietnam War (also known by other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was supported by the United States and other anti-communist allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh took control of North Vietnam, and the U.S. assumed financial and military support for the South Vietnames ...

Ford GAA Engine
The Ford GAA engine is an American all-aluminum 32-valve DOHC 60-degree liquid-cooled V8 internal combustion engine with a flat plane crankshaft designed and produced by the Ford Motor Company before and during World War II. It features twin Stromberg NA-Y5-G carburetors,Berndt, p.190. dual magnetos and twin spark plugs making up a full dual ignition system, and crossflow induction. It displaces and puts out well over of torque from idle to 2,200 rpm. The factory-rated net output was at 2,600 rpm. The GAA powered several models and derivatives of the M4A3 Sherman medium tank. Development Immediately preceding World War II, Ford developed an aircraft engine similar to the Rolls-Royce Merlin. It was a 60 degree V-12 of 1,650 cubic inch displacement with cylinder bore and stroke matching the Merlin aviation engine, using an aluminum block and head; dual overhead camshafts, and four valves per cylinder. The intention of this design was to help Ford break into the anticipated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torsion Bar Suspension
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M48 Patton, M60 Patton and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Horizontal Volute Spring Suspension
The vertical volute spring suspension system is a type of vehicle suspension system. This type of the suspension system was mainly fitted on US and Italian tanks and armored fighting vehicles starting from throughout the 1930s up until after the end of the Second World War in 1945. Development During the 1930s, many innovations in the components of light tanks would make US tanks considerably more reliable. These included rubber-bushed tracks, rear mounted radial engines and the vertical volute spring suspension. A volute spring is a compression spring in the form of a cone (a volute). Under compression the coils slide over each other, affording longer travel. The result is more stable and powerful than any leaf, coil, or torsion bar spring in the same volume. Mounted vertically in a road wheel bogie for a pair of road wheels on a tank made a very compact unit. The Rock Island Arsenal produced a small tank for the cavalry which used vertical volute spring suspension instead of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright R-975
Wright is an occupational surname originating in England. The term 'Wright' comes from the circa 700 AD Old English word 'wryhta' or 'wyrhta', meaning worker or shaper of wood. Later it became any occupational worker (for example, a shipwright is a person who builds ships), and is used as a British family name. The word's use as an occupational title continued until the mid-19th century, often combined with other words such as in shipwright, wheelwright, wainwright and playwright. '', Wright'' was the eleventh most common surname in England. The word ''carpentier'', now "carpenter", was introduced into England in the years after the Norman conquest in 1066 and slowly replaced the traditional name and meaning of wright in most of England. 'Wright' is still used in Scottish English in the original meaning of 'skilled woodworker'. The Incorporation of Wrights of the Trades House of Glasgow, and the Incorporation of Wrights and Masons of Edinburgh Trades retain the word in its o ...
