Friction on the inclined plane (TM225)

Friction on the inclined plane (TM225)

fundamentals of mechanical friction



  • Friction experiments on the inclined plane help students to understand the fundamentals of mechanical friction.
  • The main elements of TM 225are a sliding surface (the inclined plane), with an adjustable angle of inclination, and different samples.
  • A sample is moved from the stationary state to the sliding state in two ways.
  • In the first experiment, the plane is carefully tilted until the sample begins to slide downwards and the downward force is greater than the static friction force.
  • In the second experiment, a load acts as a tensile force upon the sample.
  • The load is gradually increased until the sample begins to slide in a uniform motion.
