Watch: How Luxury Mechanical Calculator Works Source: Friden SBT10 / YouTube The mechanical calculator, also known as an arithmetic calculator, is the mechanical equipment utilized to carry out the basic operations of math. The first mechanical calculator, known as Pascal’s calculator, was created in the 17th century, and exactly in 1642 by the French mathematician and physicist Blaise Pascal. Brief History Source: Ezrdr / wikicommonsSource: Friden SBT10 / YouTubeSource: Ezrdr / wikicommons The earliest mechanical calculators were proposed by polymaths and encyclopedic scientists, including Leonardo da Vinci, Wilhelm Schickard, Blaise Pascal, and Gottfried Leibniz up to the end of the 17th century. The history of mechanical calculators began in the 17th century with the introduction of Pascal’s calculator. Arithmetic tools were also created in the 17th century. Arithmometers dominated over and limited the usage of mechanical calculators until the mid-19th century introduction....

  Rust Removal With Laser (Cost, Effectiveness, Pros & Cons) image credit: Powerlase / YouTube The elimination of rust is one of the most significant functions that can be performed with a cleaning laser. Rust is a layer of oxidized material that can form on the outside of a metal’s surface. Sanding, chemical treatment, sandblasting, dry ice blasting, and other similar processes are among the traditional methods for rust removal. These methods either require a significant amount of time or negatively affect the surrounding ecosystem. What Exactly Is Meant by “Laser Rust Removal”? When it comes to cleaning metal substrates and product pieces, laser rust removal, which is a subset of laser cleaning, is an extremely useful tool. Rust and oxide deposit removal can be accomplished with a laser cleaning system. It is possible to clean the surface of the metal quickly and thoroughly without causing any damage to the underlying metal. A laser rust removal machine is an improved alterna...

   Cogeneration System Cogeneration, often known as combined heat and power (CHP), is the simultaneous production of electricity and usable heat using a heat engine or power plant. Because cogeneration uses otherwise wasted heat from producing electricity for some useful use, it is a more efficient use of fuel or heat. CHP plants recover thermal energy for heating that would otherwise be lost. District heating using combined heat and power is another name for this. One example of decentralized energy is small CHP plants. Absorption refrigerators may also utilize by-product heat at moderate temperatures (100-180 °C, 212-356 °F) for chilling. First, a generator powered by a gas or steam turbine is driven by the delivery of high-temperature heat. After that, the low-temperature waste heat is put to use heating water or a room. It is possible to employ a gas engine or diesel engine at lesser sizes (usually below 1 MW). Due to their propensity to generate relatively low-grade heat,...

  TURBOCHARGED ENGINES PROS AND CONS Despite being small in size, turbo engine can produce as much horsepower as a large engine Before proceeding to the pros and cons of turbocharging, let’s understand what turbocharging means and how turbocharging works. Turbocharging refers to the process in which the turbocharger uses a turbine to create more power from the engine and a compressor to help the engine get more air. The flow of engine exhaust gas causes the turbine to rotate, which in turn causes the compressor to operate. The compressor blows air into the engine faster than it can do on its own which improves the engine’s compression ratio. PROS OF TURBOCHARGING This section sheds light on the advantages of turbocharged engine. Fuel Efficient  — Despite being small in size, a turbocharged engine produces the amount of power a larger engine does by using less fuel. For example, if a naturally aspirated internal combustion engine produces 200 horsepower with six cylinders, the ...

  Machine Maintenance Machine maintenance is the means by which mechanical assets in a facility are kept in working order. Machinery maintenance involves regular servicing of equipment, routine checks, repair work, and replacement of worn or nonfunctional parts. Machines to be maintained include both heavy-duty industrial equipment and simple hand-operated machines. Maintenance of machinery is frequently handled reactively (e.g. after a breakdown) though it may also be done proactively, as with preventive and predictive maintenance. Preventive maintenance keeps assets in good repair through regularly scheduled service; predictive maintenance relies on equipment monitoring to detect problems before they result in a breakdown. 3 types of machinery maintenance workers In most industrial settings, there are a few different types of personnel who are involved in the maintenance process. 1. Machinery mechanics Among the duties of machinery, the mechanic is keeping industri...
