A Means of Calculating Level Road Traction Requirements 620227

Up to this time, level road traction requirements of a car could be determined only by various time-consuming road and bench tests. The development of a basic formula to compute loading for constant speed, level road operation has solved some of the cost and time problem and gives reasonable agreement with experimental values. A discussion of the variables encountered, different ways of obtaining them, and their correlation with the equation for computing traction requirements shows the application of the formula to various car dimensions and temperature/air resistance conditions
