Material Detail

This technical paper details a method of adjusting the drag factor of a vehicle when there is a difference of grade between the tested surface and the actual accident surface. This method is based on the sum of the forces acting on the object and is accurate for any grade. The popular method used by most accident reconstructionists consists of adding the signed difference in grade to the test drag factor. Many reconstructionists believe that the adjusted drag factor obtained by this second method is relatively accurate only for grades of ten percent (.1) or less.
