2. Braking distance - Wikipedia

   en.wikipedia.org/wiki/Braking_distance

   The type of brake system in use only affects trucks and large mass vehicles, which cannot supply enough force to match the static frictional force. [1] [Note 2] The braking distance is one of two principal components of the total stopping distance. The other component is the reaction distance, which is the product of the speed and the ...

3. Brake force - Wikipedia

   en.wikipedia.org/wiki/Brake_force

   British Railway Class 90 infobox showing brake force Brake force to weight ratio of the Class 67 is higher than some other locomotives. In the case of railways, it is important that staff are aware of the brake force of a train so sufficient brake power will be available to bring the train to a halt within the required distance from a given speed.

4. Pull-rod suspension - Wikipedia

   en.wikipedia.org/wiki/Pull-rod_suspension

   As such, push-rod suspension systems allow for much greater high-speed stability, much lower levels of body-roll, and a much lower centre of gravity for the vehicle. [7] For pull-rod suspension systems, the only difference is the orientation of the rocker arms. In a push-rod system, the rocker arms are placed at the highest point in the assembly.

5. Car suspension - Wikipedia

   en.wikipedia.org/wiki/Car_suspension

   The distance from this axis to the sprung center of gravity height is the roll moment arm length. The total sprung weight transfer is equal to the G-force times the sprung weight times the roll moment arm length divided by the effective track width. The front sprung weight transfer is calculated by multiplying the roll couple percentage times ...

6. Stopping sight distance - Wikipedia

   en.wikipedia.org/wiki/Stopping_sight_distance

   A deceleration rate of 3.4 m/s 2 (11.2 ft/s 2) is used to determine stopping sight distance. [6] Approximately 90 percent of all drivers decelerate at rates greater than that. These values are within most drivers' ability to stay within his or her lane and maintain steering control.

7. Brake tester - Wikipedia

   en.wikipedia.org/wiki/Brake_tester

   A roller brake tester is a method of allowing the dynamic assessment of the braking system of a motor vehicle, whilst the vehicle itself is in a static condition.This type of brake tester is normally used in UK garages when used as part of an inspection lane for the MOT test.

8. Rod (unit) - Wikipedia

   en.wikipedia.org/wiki/Rod_(unit)

   The rod, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units, it is defined as 16 + 1 ⁄ 2 feet, equal to exactly 1 ⁄ 320 of a mile, or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.

9. Prony brake - Wikipedia

   Prony brake dynamometers at a tractor contest in 1910 Schematic of a Prony brake Actual Prony Brake built for testing 5HP Steam Engine. The Prony brake is a simple device invented by Gaspard de Prony in 1821 to measure the torque produced by an engine. The term "brake horsepower" is one measurement of power derived from this method of measuring ...
