Tank steering systems allow a tank, or other continuous track vehicle, to turn. Because the tracks cannot be angled relative to the hull (in any operational design), steering must be accomplished by speeding one track up, slowing the other down (or reversing it), or a combination of both.
Christie's first tank design of 1919 could be driven on its wheels to get to the starting point and then the tracks fitted before it went into action. The US Tank Corps ordered a single tank from Christie's company based on this design. The tank, known as the M1919, was delivered in early 1921 and tested until Christie proposed modifying it ...
A British heavy tank during World War I. Modern armored warfare began during the First World War of 1914–1918. Strategists wanted to break the tactical, operational and strategic stalemates forced on commanders on the Western Front by the effectiveness of entrenched defensive infantry armed with machine guns – known as trench warfare.
Mariotte's bottle is a device that delivers a constant rate of flow from closed bottles or tanks. It is named after French physicist Edme Mariotte (1620-1684). A picture of a bottle with a gas inlet is shown in the works of Mariotte, [ 1 ] but this construction was made to show the effect of outside pressure on mercury level inside the bottle.
The ship model basins worldwide are organized in the ITTC [3] (International Towing Tank Conference) to standardize their model test procedures. Some of the most significant ship model basins are: Denny Tank in Dumbarton, Scotland. The Denny tank was the first commercial ship model basin.

Sydney Tower in Sydney has a water tank used to dampen oscillations from high winds and potentially from earthquakes. Brazil. Senna Tower in Balneário Camboriú; Canada. One Wall Centre in Vancouver employs tuned liquid column dampers, a unique form of tuned mass damper at the time of their installation. CN Tower in Toronto; China
Anti-tank warfare evolved as a countermeasure to the threat of the tank's appearance on the battlefields of the Western Front of the First World War. The tank had been developed to negate the German system of trenches, and allow a return to maneuver against enemy's flanks and to attack the rear with cavalry.
A later method used a potentiometer supplying a variable voltage to varactor diodes in the local oscillator and tank circuits of front end tuner, for electronic tuning. Modern radio tuners use a superheterodyne receiver with tuning selected by adjustment of the frequency of a local oscillator.
