Abstract:
1. A device for measuring the static and/or dynamic friction coefficient of a surface, said device comprising a frame, a first arm having a first arm end and a second arm end, said first arm being pivotally connected around a first pivot point with said first arm end to said frame and around a second pivot point with said second arm end to a first having a first bar end and a second bar end, said first bar being fitted at said first bar end with a body that has a surface placeable into contact with the surface to be measured, loading means for exerting a force on said first bar in a direction of the surface to be measured, the first bar being provided with means for measuring forces occurring in the first bar, which means are present at a point located between the second pivot point with the first arm and the first bar end, the first bar end being capable of carrying said body, said bar being connected with said second bar end around a third pivot point to means for exerting thereon a torque, which torque acts about the third pivot point thereon, thereby displacing said body relative to said frame.
