      Linear Actuator

      A linear actuator is a mechanical device that makes a linear motion, usually via a hydraulic pump or electromagnetic gear. Other forces can be used to create linear motion. The different types of linear actuators include screw, wheel and axle, cam, hydraulic pump, pneumatic, piezoelectric, and electro-mechanical. Linear motors, wax motors, and telescoping linear actuators

    • Vibration Isolators

      Vibration Isolators

      There are a number of vibration sources throughout the world. In most cases, these movements have undesirable effects on things used in daily life, such as buildings and vehicles. Vibration isolators reduce or eliminate the effects of vibrations on equipment and structures. These devices are commonly referred to as shock mounts, snubbers, machine mounts, and

    • What is a Pitot Tube?

      What is a Pitot Tube?

      A pitot tube measures pressure levels in liquids. They are most commonly seen in laboratory settings but can be seen in industrial applications as small cylinders. While a pitot tube is not the only device that measures fluid pressure, it is capable of being implemented in much more diverse environments than similar devices. How Pitot

    • How Do Xenon Lights Work?

      How Do Xenon Lights Work?

      Xenon is a noble gas–found all the way to the right on the periodic table of elements–that is odorless, colorless and heavy. It has many different uses, but one of the biggest uses that it has is the use in light bulbs. The reason for this is because when xenon is excited, it gives off

    • 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,

    • What is Microfarad?

      What is Microfarad?

      The term microfarad is used to describe a unit of capacitance that is 0.000001 farad. The symbol that represents a microfarad is µF. It is commonly used in utility alternating-current and audio frequency circuits. The capacitors that are found in them normally have a rating of 1 µF or more. However, even smaller capacitors are

    • Magnetic Permeability

      Magnetic Permeability

      Magnetic Permeability is a term refers to the ability of a material to gain or maintain magnetism. When certain materials are placed in a magnetic field they become magnetized.  For example, when you take a piece of iron and rub it on a substance already magnetized or a magnet, it will become magnetized and have a

    • The Kelvin Scale

      The Kelvin Scale

      The Kelvin Scale is a thermometric scale used in physical science to describe the absolute temperature of an object, substance, or area. While Fahrenheit and Celsius scales measure temperature, the Kelvin Scale defines temperatures relative to an object’s thermodynamic movement. As a result, the Kelvin Scale does not use degrees, but simply a number followed

    • Seebeck Effect

      Seebeck Effect

      The Seebeck Effect was first discovered in 1821. It describes the thermoelectric phenomenon that results when the temperature differences between dissimilar metals in a circuit are converted into electric current. This is one of three similar processes that relate to conductivity, temperature, and thermoelectricity that was discovered in the 1800s. The Thomson Effect was first

    • How a Convection Oven Works

      How a Convection Oven Works

      In a regular oven, a thin layer of air insulates food from the heat beneath it. This layer of air causes food to be cooked unevenly and slows cooking time down considerably. A convection oven is a type of oven that solves this problem by circulating the air within the chamber by using either one
