Fig. 3-8 shows the characteristics of accelerating ability and excess power.
The relationship between the power-defined accelerating ability and the maximum climbing ability can be determined by the relations:
Eq. 3-13
Eq. 3-14
By equating the excess traction forces:
Eq. 3-15
A proportional dependence between accelerating and climbing ability which depends on the gear due to the influence of rotational masses (in Equation 3-15 considered by ei) results.
