• ### GEARBOXES IN AUTOMOBILES

A transmission or gearbox provides speed and torque conversions from a rotating power source to another device using gear ratios, including for a motor vehicle partly because of the limitations of internal combustion engines.Usually found near motors of some sort, gearboxes are used to reduce the load on the motor by using the motor's own momentum to keep it turning.

• ### Reference Manual : Governing Fundamentals and Power Management

Interest in power systems economics is gaining momentum with the recent power supply shortages in America and the rising cost of fossil fuels. The involvement of independent power generators, brokers and distributors has changed the way in which power systems operate. Kirschen and Strbac use a combination of traditional engineering techniques and fundamental economics to address the long-term problems of power system development in a competitive environment.

• ### Vehicle Crash Dynamics P14

In general, it is the BEV (not the )V) that describes the VTV crash severities in a complete manner. Only in the fixed barrier test condition or when the stiffness ratio equals the mass ratio, will BEV (or crash severity index) be the same as )V (or crash momentum index). This relationship can be proved by simply making Rm = Rk and substituting into Eq. (7.52). Then BEV1/Vclose = )V/Vclose = 1/(1+Rm). 7.6.3 Crash Severity Assessment by a Power Curve Model This section presents a model with power curve force deflection, as shown in Fig. 7.28. The model is used...
