Добрый день!
Помогите, пожалуйста, понять выражение force applied horizontally в следующем контексте:
The EA seat back used for this study controlled its forward-folding with a combination of friction washers and dual shear pins in the hinge mechanism. The shear pins are sized to limit the contact force produced when the head of the occupant strikes the seat back from behind. This allows the seat to absorb some of the occupant’s energy prior to folding over. In this case, each pin would shear sequentially when a force of approximately 220 lb was applied horizontally at the top of the tray table, 19 in above the hinge point. During a crash, the first bolt shears due to inertial forces acting on the seat back. The second bolt then shears when the occupant comes into contact with the seat back. The resisting force provided by this energy-absorbing mechanism is considered typical for seat backs designed to limit head injury potential [11].
Заранее спасибо!

Пока тело покоится относительно доски, то она представляет собой силу трения покоя, когда же тело начнет соскальзывать — силу трения скольжения.

THEORY
When a force (F) is applied to an object resting on a surface, it will not move until the force applied to it is greater than the maximum force due to static friction. The coefficient of static friction (s) is defined to be the ratio between the maximum static frictional force (Fs) and the normal force (FN):
s = Fs/FN = Fmax/mg
where Fmax is the maximum applied horizontal force that does not cause slipping and FN equals mg since there is no vertical motion.
To keep the object moving at a constant velocity, the applied force (F) must equal the kinetic frictional force. The coefficient of kinetic friction (k) is defined to be the ratio between the kinetic frictional force (Fk) and the normal force (FN):
k = Fs/FN = F/mg
