TM 225 Friction on the Inclined Plane Show data sheet (pdf file) Print page
Technical Description

Friction experiments on the inclined plane help students to understand the fundamentals of mechanical friction.
  The main elements of TM 225 are a sliding surface (the inclined plane), with an adjustable angle of inclination, and two 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 weight acts as a tensile force upon the sample. The weight is gradually increased until the sample begins to slide upwards in a uniform motion. The angle of inclination of the plane is not altered in this experiment.


Learning Objectives / Experiments

- Determination of the friction coefficients of various material pairings
- Transition from static to dynamic
- Static equilibrium of forces on the inclined plane
- Determination of the angle of inclination as from which sliding occurs
