NASCAR tires don’t have “air pressure” because they’re filled with nitrogen. The culprit responsible for increasing tire pressure during a race is friction. Using dry nitrogen gas helps the team predict how hot the tire will get and how much the pressure will “build” during a race. http://science360.gov/obj/video/11ac7bf2-11dd-4df2-8524-373accf09dbd/science-speed-tires-pressure
SOME BASIC THOUGHTS ON DRIVING FAST
Training to avoid an emergency is difficult for both the student to learn and the instructor to teach. First and foremost all those advantages we have when driving through a corner are gone. When the officer is confronted with an emergency the amount of turning, steering and braking that is needed to get out of […]
Using the Vehicle’s Capability
There may be a time when as a police officer you will have to drive fast. Driving fast in a straight line is not much of a problem, but life can get exciting real quick if, at high speeds, you have to stop or drive through a corner. Studies have shown that while cornering (or making an emergency maneuver), the average driver can use only 40 % to 55 % of the car’s capability. This does not mean they lose control; it means they can no longer put the vehicle where they want to put the vehicle.
Backing Up
Many departments report that the number of accidents while backing up is higher than other types of accidents. More often than not, this results in fender benders. Not dramatic accidents, but still annoying and expensive. Driving in reverse is deceptively hard and has no correlation to driving forward. There is a simple reason for that. […]
Reaction Time
While driving if confronted with an emergency scenario, the driver’s reaction time can be the difference between success and failure. Although it is an important part of driving and driver training, reaction time is not easy to demonstrate. But there are exercises that can show the effect of reaction time on the decision-making process. The […]
