P40 Tank
The P 26/40 was an Italian World War II heavy tank (sometimes defined medium tank when compared to tanks of other nations). It was armed with a 75 mm gun and an 8 mm Breda machine gun, plus another optional machine gun in an anti-aircraft mount. Design had started in 1940 but very few had been built by the time Italy signed the armistice with the Allies in September 1943 and the few produced afterwards were used by the Germans. The official Italian designation was '' carro armato'' ("armoured vehicle") P 26/40. The designation means: P for ''pesante'' ("heavy"), the weight of 26 tonnes, and the year of adoption (1940). While considered a heavy tank according to Italy's standards, the P26/40 was much more similar in performance to the medium tanks of other nations. History The development work began in 1940, on Benito Mussolini's specific orders. Initial requirements were for a 20 tonne (the maximum load allowed by pontoon bridges) tank with a 47 mm gun, three machin ...

Kingdom Of Italy (1861–1946)
The Kingdom of Italy (, ) was a unitary state that existed from 17 March 1861, when Victor Emmanuel II of Kingdom of Sardinia, Sardinia was proclamation of the Kingdom of Italy, proclaimed King of Italy, until 10 June 1946, when the monarchy was abolished, following civil discontent that led to an 1946 Italian institutional referendum, institutional referendum on 2 June 1946. This resulted in a modern Italian Republic. The kingdom was established through the unification of several states over a decades-long process, called the . That process was influenced by the House of Savoy, Savoy-led Kingdom of Sardinia (1720–1861), Kingdom of Sardinia, which was one of Italy's legal Succession of states, predecessor states. In 1866, Italy Third Italian War of Independence, declared war on Austrian Empire, Austria in Italo-Prussian Alliance, alliance with Kingdom of Prussia, Prussia and, upon its victory, received the region of Veneto.

Carro Armato
''Carro Armato'' (armored vehicle) was the Italian Army's designation for tanks from 1938. This would be followed by a letter and a series of numbers. The letter would be either L, M or P meaning light, medium, and heavy tank respectively. The official Italian military tank classification differed from contemporary classifications in other countries. The numbers would follow the pattern of X/Y where X would be the weight in tonnes and Y the year of adoption (i.e. the L6/40 weighs 6 tonnes and was adopted in the year 1940).Riccio, p. 13 The following are some Carro Armatos that entered service: * Carro Armato L5/21: Fiat L5/21 light tank * Carro Armato L5/30: Fiat L5/30 light tank * Carro Armato L6/40: Fiat L6/40 light tank * Carro Armato M11/39: Fiat M11/39 medium tank * Carro Armato M13/40: Fiat M13/40 medium tank * Carro Armato M14/41: Fiat M14/41 medium tank * Carro Armato M15/42: Fiat M15/42 medium tank * Carro Armato P40: Fiat P26/40 heavy tank NOTE: The L3/33 and the L3/ ...

T-34
The T-34 is a Soviet medium tank from World War II. When introduced, its 76.2 mm (3 in) tank gun was more powerful than many of its contemporaries, and its 60-degree sloped armour provided good protection against Anti-tank warfare, anti-tank weapons. The T-34 had a profound effect on the conflict on the Eastern Front (World War II), Eastern Front, and had a long-lasting impact on tank design. The tank was praised by German generals when encountered during Operation Barbarossa, although its armour and armament were surpassed later in the war. Its main strength was its cost and production time, meaning that German panzer forces would often fight against Soviet tank forces several times their own size. The T-34 was also a critical part of the mechanized divisions that formed the backbone of the Deep operation, deep battle strategy. The T-34 was the mainstay of the Soviet Red Army armoured warfare, armoured forces throughout the war. Its general specifications remained n ...

Vehicle Armour
Military vehicles are commonly armoured (or armored; American and British English spelling differences#-our, -or, see spelling differences) to withstand the impact of Fragmentation (weaponry), shrapnel, bullets, Shell (projectile), shells, Rocket (weapon), rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships. Civilian vehicles may also be armoured. These vehicles include cars used by officials (e.g., Official state car, presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian Armored car (valuables), armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the Carjacking, hijacking of the cargo. Armour may also be used in vehicles to protect from threats other than a deliberate attack. Some spacecraft are equipped with specialised armour to protect them against im ...

Semovente 75/18
The ''Semovente da'' 75/18 was an Italian self-propelled gun of the Second World War. It was built by mounting the 75 mm Obice da 75/18 modello 34 mountain gun on the chassis of a M13/40, M14/41 or M15/42 tank. The first 60 were built using the M13/40 chassis and a subsequent 162 were built on the M14/41 chassis from 1941 to 1943. A total of 190 were built utilizing the M42 chassis before the armistice and an additional 55 were built afterwards. The Semovente da 75/18 was intended to be an interim vehicle until the heavier P40 tank could be available. History Italian artillery Colonel Sergio Berlese, who also designed the Obice da 75/18 modello 34 howitzer, suggested that Italy create an armoured fighting vehicle similar to the German StuG III assault gun, which had been successful in the French campaign in 1940. The first prototype was quickly assembled and delivered, on February 10, 1941, only 13 months after the first M13/40 tank upon which it was based. After that ...

M13/40 Tank
The Carro Armato M13/40 was an Italian World War II tank designed to replace the M11/39 in the Royal Italian Army at the start of World War II. It was the primary tank used by the Italians throughout the war. The design was influenced by the British Vickers 6-Ton and was based on the modified chassis of the earlier M11/39. Production of the M11/39 was cut short in order to get the M13/40 into production. The name refers to "M" for ''Medio'' (medium) according to the Italian tank weight standards at the time, 13 tonnes was the scheduled weight and 1940 the initial year of production. Specifications The M13 was constructed of riveted steel plates as follows: 30 mm front (as the M11), 42 mm on turret front (30 mm for the M11), 25 mm on the sides (the M11 had only 15 mm), 6 mm bottom (making it very vulnerable to mines) and 15 mm on top. The crew of four were housed in a forward fighting compartment, with the engine at the rear and transmission at th ...

Italian Ansaldo Company
Ansaldo was one of Italy's oldest and most important engineering companies, existing for 140 years from 1853 to 1993. History 19th century foundation The company was founded in 1853 as Gio. Ansaldo & C. S.A.S. by renowned players in the Genoese business world, such as Giovanni Ansaldo, Raffaele Rubattino, Giacomo Filippo Penco and Carlo Bombrini. Until the end of the 19th century, the company focused on manufacturing and repairing railway components, quickly becoming a 10,000-worker company with seven factories, and starting to expand into sectors such as shipbuilding and mechanical works in general. 20th century expansion and dissolution In 1904, Ansaldo was bought by Ferdinando Maria Perrone who, along with his sons Mario and Pio, bound the name of the Perrone family to the history of the company. Over the next twenty years, he aimed at making Ansaldo fully independent both in the ironworks and weapon-making areas, thanks to strong vertical integration. The on ...

Duopoly
A duopoly (from Greek , ; and , ) is a type of oligopoly where two firms have dominant or exclusive control over a market, and most (if not all) of the competition within that market occurs directly between them. Duopoly is the most commonly studied form of oligopoly due to its simplicity. Duopolies sell to consumers in a competitive market where the choice of an individual consumer choice cannot affect the firm in a duopoly market, as the defining characteristic of duopolies is that decisions made by each seller are dependent on what the other competitor does. Duopolies can exist in various forms, such as Cournot, Bertrand, or Stackelberg competition. These models demonstrate how firms in a duopoly can compete on output or price, depending on the assumptions made about firm behavior and market conditions. Similar features are discernible in national political systems of party duopoly. Duopoly models in economics and game theory Cournot duopoly Cournot model in game theor ...

Petrol
Gasoline (North American English) or petrol ( Commonwealth English) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. The ability of a particular gasoline blend to resist premature ignition (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded gasolines. Other substances are frequently added to gasoline to improve chemical stabilit ...

Petrol Engine
A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as '' E10'' and '' E85''). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations. Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. History The first practical petrol engine was built in 1876 in Germany by Nicolaus August Otto and Eugen Langen, although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also ...

Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...
