    • Brookfield Viscometer

      Brookfield Viscometer

      The Brookfield Viscometer makes it possible to measure viscosity by employing techniques in viscometry. Viscometers (which can also be called viscosimeters) can measure viscosity through the varying flow conditions of the sample material being tested. They employ a spindle on a shaft that is designed to be dipped or immersed into a liquid that is

    • Long Distance Wireless Power Transmission

      Long Distance Wireless Power Transmission

      Simple wireless power transmission works because of the principles of magnetic resonance and magnetic induction. This power transmission system relies on two coils in range with each other and resonating at the same frequency. The coils need to be in range because the magnetic field of the source must be strong enough for the receiving

    • What is an Acetylene Torch?

      What is an Acetylene Torch?

      Acetylene is a hydrocarbon compound and is the simplest form of alkyne. Acetylene is colorless and extremely unstable in its pure form, which is why it is almost always mixed with other chemicals and handled as a solution. Acetylene was once the preferred gas in welding/cutting applications due to its ability to reach extremely high

    • How Do X-Ray Machines Work?

      How Do X-Ray Machines Work?

      The Parts of an X-Ray Machine There are three main parts of an x-ray machine. The first is the x-ray tube. This is responsible for the creation of x-rays. Therefore, without this functioning properly, there would be little chance for the x-ray to work in the right way. It generates enough x-rays so that when

    • How to Disable Onstar

      How to Disable Onstar

      Disabling Onstar is not a task that is as simple as pushing a button. Onstar is a device that permits the vehicle to be tracked and, if something happens to the vehicle, allows an operator to conact the vehicle. For some people, there is discomfort with Onstar having the ability to track the vehicle. To

    • What is the Fifth State of Matter?

      What is the Fifth State of Matter?

      The fifth state of matter is actually the first phase of matter. It is called a Bose-Einstein Condensate. Matter in the fifth state is really slow moving and extremely condensed. It only exists at near absolute zero temperatures and is very fragile and unstable. It was discovered in 1995 by Eric Cornell and Carl Weiman through experimentation with rubidium,

    • Terahertz Radiation

      Terahertz Radiation

      Terahertz radiation is a selection of the electromagnetic wave spectrum that propagates at frequencies regarded as the terahertz band. ‘Radiation physics of energetic waves’ defines the terahertz band as tremendously high frequency. The terahertz band can be applied within the bracket of 300 gigahertz (high frequency microwave) and 3000 gigahertz (long wavelength far infrared light).

    • How Do Light Bulbs Work?

      How Do Light Bulbs Work?

      The light bulb, invented in 1854, has been a crucial component of civilization since. Contrary to popular belief, the light bulb was invented by Henricg Globel, a German watchmaker, not Thomas Edison. Edison did improve on the idea of the incandescent light bulb, though, and strived to make it better. Due to the works of

    • What is a Karnaugh Map?

      What is a Karnaugh Map?

      A Karnaugh map is a graphical method or shortcut that can be used to solve Boolean algebra problems. Boolean algebra is used to conduct computations and create expressions from two values. This type of math creates the basis behind much of computer science and modern circuit card design today. Maurice Karnaugh created the current version

    • Vibration Measurement

      Vibration Measurement

      Vibration measurements are made in order to identify when preventive or corrective repairs are required on machinery. These repairs are made in order to reduce or eliminate the noise that damaged equipment make. This prevents catastrophic failure of the equipment. Vibration measurements are frequently made on process control equipment and rotating machinery such as the
