The rate of change of the working air gap stored energy provides the axial magnetic force.
Because arch and tie are mainly subject to axial forces, their cross sections can be very small.
The axial or feed force acts in the longitudinal direction.
In an unstable orientation, both axial forces are directed away from the center of the gear.
This axial force is given by friction and pressure.
The tibia has been modeled as taking an axial force during walking that is up to 4.7 bodyweight.
The steel core is to resist the full axial force developed in the bracing.
The axial force takes place due to both the pressure difference and change of momentum in the axial direction.
There is also a thrust block, a bearing to resist the axial force of the propeller.
Furthermore, the normal and axial forces will have no effect, so tangential force must be provided by friction.
