Hydraulic Press Channel (HPC) is a YouTube channel operated by Finnish workshop owner Lauri Vuohensilta. Launched in October 2015, the channel publishes videos of various objects being crushed in a hydraulic press , as well as occasional experiments using different devices.
The hydraulic press depends on Pascal's principle.The pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force.
Alcoa ran the plant from the time of its construction, and purchased it outright in 1982. In 2008, cracks were discovered in the press, which had to be shut down for safety reasons. [3] Repairs, originally estimated at a cost of $68 million (equivalent to $96.57 million in 2023), cost a total of $100 million, and were completed in early 2012. [4]
The Wyman-Gordon 50,000-ton forging press. The Heavy Press Program was a Cold War-era program of the United States Air Force to build the largest forging presses and extrusion presses in the world. These machines greatly enhanced the US defense industry's capacity to forge large complex components out of light alloys, such as magnesium and ...
1439: Printing press in Mainz, Germany: The printing press is invented in the Holy Roman Empire by Johannes Gutenberg before 1440, based on existing screw presses. The first confirmed record of a press appeared in a 1439 lawsuit against Gutenberg. [375] Mid 15th century: The Arquebus (also spelled Harquebus) is invented, possibly in Spain. [376 ...
A forming press, commonly shortened to press, is a machine tool that changes the shape of a work-piece by the application of pressure. [1] The operator of a forming press is known as a press-tool setter, often shortened to tool-setter. Presses can be classified according to their mechanism: hydraulic, mechanical, pneumatic;
Bramah was a very prolific inventor, though not all of his inventions were as important as his hydraulic press. They included: a beer engine (1797), a planing machine (1802), a paper-making machine (1805), a machine for automatically printing bank notes with sequential serial numbers (1806), and a machine for making quill pen nibs (1809).
For an object to be in static equilibrium, not only must the sum of the forces be zero, but also the sum of the torques (moments) about any point. For a two-dimensional situation with horizontal and vertical forces, the sum of the forces requirement is two equations: Σ H = 0 and Σ V = 0 , and the torque a third equation: Σ τ = 0 .
