Modulator

A pressure control or adjusting valve used in the hydraulic system (i.e., Hydraulic modulator) of the Automatic transmission. When the vehicle is under heavy load or full throttle, the modulator increases the pressure to hold the Clutches in place. In a light load situation, the modulator reduces pressure to give smoother shifts. If the vehicle tends to stay in Low gear, shifts with difficulty, or produces a white smoke, and has low Transmission fluid or has leaked Transmission fluid, you have a Transmission problem. It may be cured by an expensive repair or by simply replacing the modulator. Also called Vacuum modulator.
The unit in a wheel slip brake control system which adjusts brake actuating force in response to input signals.

Moment of inertia: This is similar to Inertia except that it relates to rotating movement rather than linear movement. Linear movement is the tendency of an object to remain motionless if at rest and to keep moving in a straight line if already in motion. The moment of inertia, however, is the tendency of an object to resist being accelerated when it is rotating. The polar moment of inertia is the rotating movement around a vertical axis through the center of rotation. It greatly affects steering and handling response in an automobile. The greater the length of the axis the greater the polar moment of inertia. By having the heavy Components of a vehicle such as the engine and Transmission between the two front wheels, the polar moment of inertia is low so that the tires can easily change the direction of the vehicle.

Also See

Money factor

When purchasing a vehicle, the characteristics of its engine, appearance, and appointments may be very appealing, but the money factor (i.e., its cost) may be prohibitive.
The most common way to express the base interest rate of a lease is as a money factor. If you multiply a money factor by 2400, the result will be equivalent to the base interest rate. The money factor of most leases is known by a dealer's sales staff. The money factor measures the cost of money, just like an interest rate. However, money factors are used almost exclusively in leases, whereas interest rates are used everywhere else.

Monkey wrench: A tool which is similar to a Pipe wrench. While a pipe wrench has teeth and a loosely mounted head that allows it to bite into the pipe and tighten as a strain is put on the handle, a monkey wrench has adjustable, smooth jaws that always remain parallel. The money wrench is used for turning pipe unions, the heads of bolts, and other flat surfaced object. The monkey wrench has pretty much been replaced by the Crescent wrench and other more modern adjustable wrenches. Monkey wrenches are still used on old steam engines (not necessarily locomotives) and boiler fittings. Some call it a steamboat wrench. (definition submitted by George King III). The expression throw a monkey wrench into something generally means to sabotage something or to cause a problem or delay in performing repairs.
