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.In relation to angle A, whose magnitude is denoted by 6, side a is known as the opposite side, side b is known as the adjacent side, and ... The ratio: CB/AB is the sine of 6 or angle A, written as sin 6 or sin A AC/AB is the cosine of 6 or angle A, written as cos 6 or cos A CB/AC is ... Side a becomes the adjacent side Side b becomes the 104 Traffic Accident Field Measurements and Scale Diagrams Manual.
