Crash Calc is a subscription based application that contains a collection of the most commonly used formulas for traffic accident reconstruction. Available in both US (Imperial) and Metric measurements. Easily calculate your results and save them for your files, all done right on your phone. Never have to wait to get back to the office again. With your monthly or yearly subscription you will find Crash Calc is broken down into seven logical categories of formulas. • Drag Factors – Calculate your drag factors by several different ways then adjust for braking, slope and super-elevation. • Speed – Includes speed conversation to velocity, speed formulas and then momentum of both in-line crashes as well as angular crashes. • Time-Distance-Velocity – Explore the relationship between the three variables. • Kinetic Energy – Calculate the energy present during a crash and force required to produce damage. Includes KE formulas, Vector Sum Analysis and Crush formulas. • Center-of-Mass, Radius, Critical Speed and Roll-Over – Grouped together to easily move from one formula to the next. • Airborne – Calculate speed required to travel from takeoff to landing • Miscellaneous section includes a Pedestrian formula, Motorcycle formulas and Swerve to Avoid formula • Slope Indicator – Use this feature to easily find the slope of the roadway in question.
