Track (measured between center line of wheels) In automobiles (and other wheeled vehicles which have two wheels on an axle), the axle track is the distance between the hub flanges on an axle. [1] Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. In the case of an axle with ...
In 2017, a group led by Michael Stevens performed the first realistic trolley-problem experiment, where subjects were placed alone in what they thought was a train-switching station, and shown footage that they thought was real (but was actually prerecorded) of a train going down a track, with five workers on the main track, and one on the ...
The American gauges converged, as the advantages of equipment interchange became increasingly apparent. Notably, all the 5 ft (1,524 mm) broad gauge track in the South was converted to "almost standard" gauge 4 ft 9 in (1,448 mm) over the course of two days beginning on 31 May 1886.

Used to help drivers with their cars and improve the track's condition before racing. house car A chassis manufacturer's research and development car. [33] hydrolocking Excessive fuel entering ("flooding") one or more cylinders due to abnormal operating conditions.
While speed bumps generally slow cars to 10–15 km/h (5–10 mph), humps slow cars to 25–30 km/h (15–20 mph). The narrow traverse distance of speed bumps often allows vehicles to pass over them at high speed with only mild disturbance to the wheels and suspension, and hardly affecting the vehicle cab and its occupants.
Multiple choice questions lend themselves to the development of objective assessment items, but without author training, questions can be subjective in nature. Because this style of test does not require a teacher to interpret answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher bias in the results. [8]
During corner entry the front tires, in addition to generating part of the lateral force required to accelerate the car's centre of mass into the turn, also generate a torque about the car's vertical axis that starts the car rotating into the turn. However, the lateral force being generated by the rear tires is acting in the opposite torsional ...
Traffic psychology is a discipline of psychology that studies the relationship between psychological processes and the behavior of road users. In general, traffic psychology aims to apply theoretical aspects of psychology in order to improve traffic mobility by helping to develop and apply crash countermeasures, as well as by guiding desired behaviors through education and the motivation of ...
