Simplified diagram of gear inches: As the rear sprocket is halfed in size, the distance traveled by the rear wheel doubles, at half the torque. Gear inches is an imperial measure corresponding to the diameter in inches of the drive wheel of a penny-farthing bicycle with equivalent (direct-drive) gearing.
Thus, in a car with a short wheelbase ("SWB"), the short lever arm from the CM to the rear wheel will result in a greater lateral force on the rear tire which means greater acceleration and less time for the driver to adjust and prevent a spin out or worse. Wheelbases provide the basis for one of the most common vehicle size class systems.
A gear train or gear set is a machine element of a mechanical system formed by mounting two or more gears on a frame such that the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next. [ 2 ]
Full-size GM vans continued featuring drum brakes for several more years, transitioning entirely to disc brakes by 2003. [5] The original design of the braking system within the 14-bolt differentials accommodated diverse wheel sizes, initially fitting drums suitable for 15-inch wheels and later adapting to cater to the needs of 3/4-ton and 1 ...
Along with clearance, length of overhangs affects the approach and departure angles, which measure the vehicle's ability to overcome steep obstacles and rough terrain.The longer the front overhang, the smaller is the approach angle, and thus lesser the car's ability to climb or descend steep ramps without damaging the front bumpers.

It is used as a measure of the effective size of a gear. The test radius of the master, plus the test radius of the work gear is the set up center distance on a composite action test device. Test radius is not the same as the operating pitch radii of two tightly meshing gears unless both are perfect and to basic or standard tooth thickness. [1]

The transmission control unit (TCU) in older automobiles with a clutchless manual transmission (without a clutch pedal) typically consists of an electrical switch connected to the gearshift, that is activated whenever the internal transmission control unit senses driver touching the gearshift to switch gears, which then primes a sensor or ...
