(n.)
A small difference in rates which competing railroad lines, in establishing a common tariff, allow one of their number to make, in order to get a fair share of the business. The lower rate is called a differential rate. Differentials are also sometimes granted to cities.

differential

differential
galvanometer (elec.), a galvanometer having two coils or circuits, usually equal, through which currents passing in opposite directions are measured by the difference of their effect upon the needle.
differential
gearing, a train of toothed wheels, usually an epicyclic train, so arranged as to constitute a differential motion.
differential
motion, a mechanism in which a simple differential combination produces such a change of motion or force as would, with ordinary compound arrangements, require a considerable train of parts. it is used for overcoming great resistance or producing very slow or very rapid motion.

Differential Definition from Business & Finance Dictionaries & Glossaries
An amount added or deducted from base rate to make a rate to or from some other point or via another route. (MARAD2)
The gear assembly on the drive axle that permits the wheels to turn at different speeds; no-slip or limited-slip type: a gear assembly on the drive axle that will not permit one wheel to spin while the other is motionless. (TII1) (TII2)
By the Bureau of Transportation Statistics.
A small charge, typically 1/8 point, added to the purchase price and subtracted from the selling price by the dealer for odd-lot quantities.

the difference in quantity or degree between two measurements or units. For example, the pressure differential across a choke is the variation between the pressure on one side and that on the other. (See differential pressure.)
Differential Definition from Science & Technology Dictionaries & Glossaries
A unit that takes the power of the rotating driveshaft at right angles to the rear axle and passes it to the axle. It will not only drive both rear axles at the same time, but will also allow them to turn at different speeds when negotiating turns. In this way the tires do not scuff or skid . Also see limited-slip differential .
For an on/off controller, it refers to the temperature difference between the temperature at which the controller turns heat off and the temperature at which the heat is turned back on. It is expressed in degrees.
Differential Definition from Encyclopedia Dictionaries & Glossaries
Differential may refer to:
Mathematics
- Differential (mathematics) comprises multiple related meanings of the word, both in calculus and differential geometry, such as an infinitesimal change in the value of a function
- Differential algebra
- Differential calculus
- Differential of a function, represents a change in the linearization of a function
- Differential (infinitesimal) (e.g. dx, dy, dt etc.) are interpreted as infinitesimals
- Differential topology, in multivariable calculus, the differential of a smooth map between Euclidean spaces or differentiable manifolds is the approximating linear map between the tangent spaces, called pushforward (differential)
- Differential geometry, exterior differential, or exterior derivative, is a generalization to differential forms of the notion of differential of a function on a differentiable manifold
- Differential (coboundary), in homological algebra and algebraic topology, one of the maps of a cochain complex
- Differential cryptanalysis, a pair consisting of the difference, usually computed by XOR, between two plaintexts, and the difference of the corresponding ciphertexts
