The distance in the direction of travel from front to rear wheels of a vehicle, measured between centers of ground contact under each wheel. For a vehicle with two rear axles, the rear measuring point is on the ground midway between rear axles. Tread of a vehicle is the distance perpendicular to the direction of travel between front wheels, or between rear wheels, measured from centers of ground contact.
Industry:Science
Specialized structures found in plant cells, diverse in distribution, size, shape, composition, structure, function, and mode of development.
Industry:Science
The imposition of a metal or composite barrier between one or more sources of electrical noise and their victims with the objective of reducing or eliminating electrical interference. Examples of the barrier are the case or housing of equipment; shields covering interconnecting cables between equipment; large cabinets, racks, or consoles; shielded (screen) rooms; and entire shielded buildings or vehicles.
Industry:Science
The final stage in multistage amplifiers, such as audio amplifiers and radio transmitters, designed to deliver appreciable power to the load.
Industry:Science
The intentional difference in dimensions of mating mechanical parts that permits them to move relative to each other. A free running fit has liberal allowance; it is used on high-speed rotating journals or shafts. A medium fit has less allowance; it is used on low-speed rotating shafts and for sliding parts. Running fits are affected markedly by their surface finish and the effectiveness of lubrication.
Industry:Science
The change in rotation as a function of wavelength experienced by linearly polarized light as it passes through an optically active substance.
Industry:Science
Stratospheric ozone depletion was arguably the most important global-scale environmental problem of the twentieth century, and global warming may be the greatest for the twenty-first century. Since these two phenomena are largely caused by emissions of different gases, they have usually been thought of as independent. Recently, scientists have realized that these two may be more connected than was believed.
Industry:Science
The lac resin (secreted by the lac insect) when used in flake (or shell) form. Shellac varnish is a solution of shellac in denatured alcohol.
Industry:Science
Systems that comprise those parts of an electric power system between the subtransmission system and the consumers' service switches. It includes distribution substations; primary distribution feeders; distribution transformers; secondary circuits, including the services to the consumer; and appropriate protective and control devices. Sometimes, the subtransmission system is also included in the definition.
Industry:Science
