total mechanical power is reduced into a new, simple relation: P =F x⋅vx +F y ⋅vy +M z ⋅ωz (5) This is the formula to obtain the power consumption in the center of the dynamometer with the forces and moments provided by dynamometer. But to be closer to reality, one has to obtain this power at the tip of the tooth. For this it is
