In addition to being directly specified, the alternating load factor YA can also be calculated by specifying the basic number of load cycles NG and the stress ratio R.
Pulsating load: R = 0
Purely alternating load: R = -1

The goal of the project was to make a detailed determination of the reduction of the tooth root load carrying capacity under changing loads as a result of periodic reversals of the load direction and the stress ratio R.
