What is being measured in yaw situation is the radius of the marks. This is accomplished by taking chord and middle ordinate measurements as shown in this photograph. Calculating the coefficient of friction can be done in a variety of ways, including skids tests, computers or drag sleds. In this photograph the student utilizes a CTEC drag sled. Lecturers in and out of the classroom are designed to introduce students to concepts from basic to advanced in a structured manner.
Instructors are always available to clarify issues and provide one on one instruction when needed.
Students learn how to accurately measure collision scenes by basic coordinate and triangulation methods. Mock collision scenes are set up so that students can experience and practice measurement exercises. Once the field sketch and measurements have been completed, students then create a plan drawing using basic drafting techniques.
