This new second edition has been prepared to meet the everyday field requirements of traffic accident investigators and reconstructionists who have a responsibility to obtain and document measurements at traffic crash scenes as well as those who have the responsibility to prepare follow-up plans or scale drawings from such measurements. The manual explains in detail the various types of situations requiring measurements that can be encountered during the on-scene investigation. These are followed by a large variety of examples of how to take measurements and document them in an easily understood and appropriate manner. Examples are accompanied by solutions to problems and, in applicable circumstances, mathematical solutions are worked out in both the United States (Imperial) and metric (SI) measurement systems. The author conveys an authoritative understanding of triangulation, coordinate and grid measurements, angles, circles, curves, and includes horizontal and vertical measurements. The book is generously illustrated, and the appendices contain the United States to metric conversion tables, mathematical tables, and traffic accident investigation measurement record forms.PARTS OF A CIRCLE 5.002 The parts of a circle include the following: Curve, or arc. A part of the circumference of a circle. Central angle. The angle formed by two radii. Chord. A straight line connecting the extremities of an arc, or curve, anbsp;...
