  2. Motor constants - Wikipedia

    The torque on shaft is 0.0053 N⋅m at 2 A because of the assumed radius of the rotor (exactly 1 m). Assuming a different radius would change the linear K v {\displaystyle K_{\text{v}}} but would not change the final torque result.

  3. Prony brake - Wikipedia

    en.wikipedia.org/wiki/Prony_brake

    The torque is then related to the lever length, shaft diameter and measured force. The device is generally used over a range of engine speeds to obtain power and torque curves for the engine, since there is a non-linear relationship between torque and engine speed for most engine types. Power output in SI units may be calculated as follows:

  4. Torque - Wikipedia

    en.wikipedia.org/wiki/Torque

    Torque has the dimension of force times distance, symbolically T −2 L 2 M and those fundamental dimensions are the same as that for energy or work. Official SI literature indicates newton-metre, is properly denoted N⋅m, as the unit for torque; although this is dimensionally equivalent to the joule, which is not used for torque.

  5. Engine power - Wikipedia

    en.wikipedia.org/wiki/Engine_power

    Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ISO 1585.

  6. Drive shaft - Wikipedia

    en.wikipedia.org/wiki/Drive_shaft

    Modern light cars with all-wheel drive (notably Audi or the Fiat Panda) may use a system that more closely resembles a front-wheel drive layout. The transmission and final drive for the front axle are combined into one housing alongside the engine, and a single drive shaft runs the length of the car to the rear axle.

  7. Effective torque - Wikipedia

    en.wikipedia.org/wiki/Effective_torque

    Effective torque (often referred to as wheel torque or torque to the wheels) is a concept primarily associated with automotive tuning. Torque can be measured using a dynamometer. Common units used in automotive applications can include foot-pounds and Newton·meters. [1] The formula for effective torque to the wheels is: [2] Tw = Te * N tf * η ...

  8. Overdrive (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Overdrive_(mechanics)

    The reason for this separation of duties between the front and back of the car was to allow the drive shaft to run at lower torque, by using higher RPM. As power is the product of RPM and torque, running the shaft at higher RPM allowed more power to be transferred at lower torque. Doing so reduced the torque the driveshaft had to carry, and ...

  9. Maximum brake torque - Wikipedia

    en.wikipedia.org/wiki/Maximum_brake_torque

    Maximum brake torque (MBT) is the use of optimal ignition timing to take advantage of an internal combustion engine's maximum power and efficiency. There is always an optimal spark timing for all operating conditions of an engine.
