Definition

EN

quotient of the component of a force normal to a surface and its area:

p = e n F A

where e n is unit vector of the surface normal,

F is force (force) and A is area (ISO 80000-3: Space and time)

FR

quotient de la composante d'une force perpendiculaire à une surface par l'aire de cette surface :

p = e n F A

où e n est le vecteur unité de la normale à la surface, F est une force (force) et A est une aire (ISO 80000-3: Space and time)
