An analysis of the car crashes in mathematical calculations

Accident Reconstructionists rely on a wide range of methods to record and analyze motor vehicle accident information. Lets address contemporary methods of obtaining and analyzing collisions with emphasis on G force explanation for biomechanical analysis. Traffic accident reconstruction is the effort to determine, from whatever resources are available, how an accident happened.

Helped Me Skid Marks and Accident Reconstruction and Investigation - The Skid Mark Equation In a college algebra course, we may learn that "the stopping distance of a car is directly proportional to the square of its speed.

To accurately use this formula, one must: Experimentally determine the constant k for the particular vehicle in question driven on the same pavement, in the same driving conditions.

Drive at a known speed V. Measure the skid mark D. Use this data to solve for k. My brother-in-law a former law enforcement officermyself, and my sons decided to try out this formula by conducting our own experiment.

As the test driver, I locked up the brakes on my Kia at a speed of 30 MPH several times to get an average skid mark of 33 ft, 4" or Surprisingly, the extra 5MPH resulted in a skid mark of 50ft!

According to our formula. When measuring the skid mark, you need to measure from where the mark first begins, however faint.

This was pointed out to me by retired Deputy Murray as we were conducting this experiment. Factors To Consider In the tests shown on the video, the skid mark equation worked quite well because we obtained the constant k using the actual vehicle on the actual pavement.

Other factors to take into account include: Is the pavement wet or slippery? Investigators account for this by actually doing a pavement test at the scene.

What are the condition of tires? Again, investigators account for this and adjust calculations. Is there an incline to the pavement up or down? If so, this must be recorded and the calculation must be adjusted. Did the car impact some other car or object while skidding?

If so, a modified formula must be used.Numerical analysis is the study of algorithms that use numerical approximation Numerical analysis continues this long tradition of practical mathematical calculations. Car companies can improve the crash safety of their vehicles by using computer simulations of car crashes.

If so, this must be recorded and the calculation must be adjusted. Did the car impact some other car or object while skidding? If so, a modified formula must be used. Sep 04,  · Skidmarks & Math Used In Accident Investigation Michael Sakowski.

Numerical analysis is the study of algorithms that use numerical approximation (as opposed to general symbolic manipulations) for the problems of mathematical analysis (as distinguished from discrete mathematics).

Numerical analysis naturally finds application in all fields of engineering and the physical sciences, but in the 21st century also.

This paper presents some cases of simulation of some road situations by mathematical methods of calculations, which now are widely used for evaluation of accuracy of values of the calculated parameter (in this paper -- the braking distance).
