A body at rest remains at rest, and a body in motion remains in motion with constant velocity along the same straight line unless acted upon by some outside force. Starting with the beginning of the yawmark, if a relatively short chord is used, the calculated radius will be relatively high and the calculated speed will be relatively high.

The acceleration, a, is proportional to the force, F, and the constant of proportionality, m, is called the mass of the body. Another statement is the following: Two stiffness coefficients, A and B, define the force-damage curve.

The general procedure for this faulty method has the following steps: The art of collision analysis is to determine which event to solve first and then how to proceed with the next calculation to develop a unified collision sequence analysis. The weight load calculation for passenger C would be: Calculations, as from a popular AI TOOLS computer program, help to address specific information needed in order to piece together the accident reconstruction.

Review Witness Statements, Expert Testimony and Other Information Witness statements and expert testimony can be used to assist the reconstructionist in determining how or why the accident happened. List of numerical analysis software and Comparison of numerical analysis software Since the late twentieth century, most algorithms are implemented in a variety of programming languages.

Root-finding algorithms are used to solve nonlinear equations they are so named since a root of a function is an argument for which the function yields zero. Brake Systems, Tires, Air Bags, Seat Belts, and other safety equipment Accident Scene Mapping, which shows how the accident happened using drawings, animations, or 3-D simulation videos When you have a need for the investigation of an accident, call one of our professional engineers.

As an illustration, consider the study by Glennon and Weaver1 that shows that drivers consistently steer sharper radii than the radius of the roadway curve.

The average G calculation is included in the full publication The average forward load on Persons A, B, and C can be calculated by multiplying each persons weight by each persons average G load. Up to a certain force level, there is no permanent damage and beyond that point, permanent damage increases with increased force.

If a relatively long chord is used, the calculated radius will be lower and the calculated speed will be lower. Location of bruises and contusions can also be addressed, since these injuries can sometimes indicate use or nonuse of a seat belt or shoulder harness Head injuries are important clues.

Unification of these concepts reveals that force direction must be the same as the direction of the acceleration because mass does not have a directional property.

Fundamental to a solution for speed change are appropriate A and B values for a specific vehicle.The following table shows a series of similar calculations, demonstrating the dramatic difference between the theoretical critical speed and a more realistic critical speed: Table 2 Comparison Of Critical Speed Calculation Methods.
