fundamentals of mechanical friction

Description:

• 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.
