      Angular Acceleration

      Angular acceleration is the rate of change of a body’s angular velocity compared to time. It is considered a vector quantity since it has a direction and magnitude. Angular acceleration is similar to linear acceleration except that it travels on an arc. Scientifically, it is equal to (final angular velocity – initial angular velocity) /

    • Hot Water Circulators

      Hot Water Circulators

      A hot water circulator (circulator pump) is a device that circulates hot water through a house’s pipes so that hot water is always instantly available. In traditional one-way plumbing systems, water is run through a hot water heater and directed through the pipes towards the taps whenever a tap is turned on. When a tap

    • Throttle Position Sensor

      Throttle Position Sensor

      A throttle position sensor is a device that can detect a difference in throttle position. The Engine Control Unit (ECU) uses throttle position sensors in internal combustion engines to gauge the throttle’s position as well as the rate of change in the throttle’s position in order to relay this information to other devices in the

    • Hybrid Cars

      Hybrid Cars

      Most hybrid cars use a combination of gasoline and electric engines. There are also types of hybrid cars that use a combination of diesel and electric engines. Gasoline & Electric -Powered Cars ‘Regular’ gasoline-powered cars derive their propulsion power from combustion of gasoline. The combustion of gas produces the energy needed to turn the transmission

    • How a Laser Cutter Works

      How a Laser Cutter Works

      A Laser cutter is a machine that uses a laser to cut materials. The Laser Cutter works by making the laser enter through the side of the material that needs to be cut and shoots it through the axis of the beam. If a cut needs to be made and there are no edges near

    • What is a Permeable Membrane?

      What is a Permeable Membrane?

      A membrane is a barrier that prevents entry of materials. Membranes can be permeable, which allows certain materials to go in and out of the barrier based on a variety of factors. Permeable Membrane in Biology In biology, a simple example of a permeable membrane is a cell wall. In both plant and animal cells,

    • Electromotive Force

      Electromotive Force

      Electromotive force is the electrical potential energy that causes current to flow through a circuit. It results from the difference in charge between two points in a material. This difference is created when an external source such as a battery makes electrons move to both points so that there is an excess at the first

    • What is a Rotameter?

      What is a Rotameter?

      A rotameter is a device that measures the flow rate of a liquid or gas in a tube. Karl Kueppers invented the rotameter in 1908, which has been widely used since then for a variety of applications. Rotameters are included in a class of devices known as “variable area meters” that depend on the substance

    • Linear Particle Accelerator

      Linear Particle Accelerator

      A linear particle accelerator is a large device that can speed up electrons, ions, or other particles and slam them into a target in order to release subatomic particles and radiation. Sensors then record these by-products, send their data to a central computer system that creates a digital, 3D image of the particle, and labels

    • Types of Robots

      Types of Robots

      A robot is a mechanical or virtual artificial agent that software, hardware, or firmware programming controls/guides. Most robots today are programmed to complete tasks on their own or via human direction. No longer a product of science fiction, there are a number of industries today that use of various types of robots. These include the
