- Track (rail transport) The track on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon.

Thread: What does a HID ballast do? In this mode, the voltage present across the lamp's terminals may be anywhere between 70-300V, depending on the lamp and application. A similar ballast is used for CCFL lighting found in LCD panel backlights (laptops, camcorders, digital cameras, and what have you) and some newer CCFL flashlights.

Ballast, Supporting The Rails and Ties Ballast also acts as a support base for the railroad track structure giving it strength and rigidity but also allowing for flexibility when trains pass over. Limestone or quartz is often most used as ballasting because it is a hard stone that will lock together providing for extra strength.

- By the 1980s, designers were integrating concrete pavers into ballast roof designs, creating access paths, pedestrian walkways, and even rooftop plazas. When the green building movement came along in the late 1990s, it was natural to transition the ballast from stone to soil, creating vegetated or green roofs.

How much power does my lamp really use? A good ballast will have a power factor above 0.9 (i.e. more than 90% of the power it draws is used to power the bulb). Cheaper (lower quality) ballasts often have power factors of 0.5 or less. That's right, only half of the power gets to the bulb.

What is ballast! Ballast is the main ingredient in concrete and is a proportional mixture of sharp sand and aggregate. Concrete is made up of 4 parts aggregate, 2 parts sharp sand, 1 part cement and water.The bit that is aggregate and sharp sand is known collectively as as 'ballast' and is sold as such ready-mixed in tonne bags etc.hirdly ballast is a sand and stones/chips mix, typically 10mm to 20 mm size stones.Mix this with cement and you get concrete.

Formula One car However, all F1 cars weigh significantly less than this (some as little as 440 kg ) so teams add ballast to the cars to bring them up to the minimum legal weight. The advantage of using ballast is that it can be placed anywhere in the car to provide ideal weight distribution. 18 people found this useful.

What is a Lighting Ballast? For high-powered lights, however, a resistor would waste a large amount of electricity, so a more complex lighting ballast is required. An electromagnetic lighting ballast uses electromagnetic induction to provide the starting and operating voltages of a gas discharge light. Inside each is a coil of wire and an electromagnetic field that together transform voltage. Some also include an igniter for high-power applications.

What are Ballasts? What are Ballasts? If you have been doing any sort of research on purchasing an HID conversion you will inevitably come across the term ballast. What ballasts do in a conversion kit is relatively simple. The wiring harness that your car uses to power the stock halogen bulbs usually run at 55w. When you upgrade to an HID conversion, the bulbs that are used only require 35w (as a general rule of course).

Why you place stones beneath trains? You put ballast (stones) beneath the rails to improve DRAINAGE, because the ties are wooden, they'll rot if they're stuck in the dirt or mud. Modern concrete ties will decom…pose if not properly drained with ballast. If something comes along nothing holds you back Real life is not found in inactivity.

Fluorescent lamp A fluorescent lamp or a fluorescent tube is a low pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to glow.he light output and performance of fluorescent lamps is critically affected by the temperature of the bulb wall and its effect on the partial pressure of mercury vapor within the lamp. Each lamp contains a small amount of mercury, which must vaporize to support the lamp current and generate light.

- All fluorescent light fixtures consist of at least lamp(s), lamp holders, ballast and internal wiring. Some older types have starters, too. The ballast is used to create the voltage and current necessary to start and illuminate the fluorescent lamp. In time, the ballast may need to be replaced.
