Engineering scientists in motor vehicle crash investigations use forensic evidence to measure and analyze the variables involved in a car crash. ""Crashes and Collapses"" examines forensic cases and investigative methods from the forensic engineering sciences, which include the physical sciences as well as all of the engineering fields. The engineering sciences dominate forensic investigations of events underlying civil disputes while also playing an important role in criminal investigations, especially in those in which a crime has been disguised as an accident. ""Crashes and Collapses"" provides middle and high school students with a unique look at this area of forensic science. After providing a history of forensic engineering science, this compelling new volume goes on to introduce Newton's laws of motion, which underlie accident reconstruction; the critical-speed-scuff method for determining the speed of cars; the obstacles confronting forensic investigators; and, more. The book also provides enlightening looks at specific cases of crashes and collapses, presenting both the facts and analyses.
