Principle

Demonstrate that sliding friction is:

  • smaller than static friction
  • proportional to the normal force

  • a function of the nature of the contact surfaces

and

  • independent of the size of the contact surface.

 

Benefits

  • Optimised for demonstration experiments: Transformation from horizontal into vertical direction
  • Very good visibility: Big devices on uniform background
  • Strong Magnets (at least 10 N) allow a safe mounting and therefore a very easy handling
  • Demonstrative measurement of forces with large circular dynamometers with a fixing magnet and ball-bearing pulley with two cord grooves for two measuring ranges
