Three support friction surfaces with a total of four different surfaces
Carriage driven by cable pulley and motor
Mechanical friction between two solid bodies
Friction body stationary, support friction surface in a moving carriage
Two driving speeds via a graduated cable drum
Force measuring unit: force gauge and adjustable air damper
Force measuring unit height-adjustable
Adjustable air damper - with damping: Measurement of a mean friction force adjusted by disturbances, without damping: Slip/stick effects measurable
Two friction bodies each with two different surfaces
Lines of action of friction force and tensile force always parallel
Box to house the components.
