For the effective force F
acceleration forces, for example caused by vibrations or start−up processes) have to be
taken into consideration.

If forces act from several directions, e.g. in the case of a moving horizontal travelling
drive, the acting forces have to be added vectorially (e.g. vertical force due to weight plus
horizontal acceleration force).
F corresponds to the maximum value of the forces added vectorially!
