Using the principle of virtual velocities presented a demonstration to calculate power flux indicator. Finally, examples of the method for calculation of differential type mechanisms. %K kinematic %K forces %K transfer ratio %U http://www.utgjiu.ro/rev_mec/mecanica/pdf/2010-02/3_Plosceanu%20Barbu.pdf
