Additional moment of inertia due to wheels, axes, etc.
• Has an impact on the dynamic torque!
• Value can be entered directly or calculated using the inertial calculator.

β
Angle of tilt (gradient)
• The value can be entered in degrees or as a percentage.
• The max. angle of tilt as a first approximation is: arctan(μ
0
)
(static friction between the wheel and road surface).
• The angle of tilt of the travel path must be considered when determining the travelling re-
sistance. For a tilted travel path (β ≠ 0), the specific travelling resistance must be recalculated
by means of the "Travelling resistance" calculator and the values for the wheel diameter and
the angle of tilt.
