Friction Apparatus
Teaching objectives of
Friction Apparatus
- Investigate the relationship between the friction force and the surfaces in contact.
- Compare the value of the coefficient of sliding friction between dry surfaces of various materials.
- Compare the value of the coefficient of sliding friction between dry and lubricated surfaces
- Compare the force of friction between sliding and rolling surfaces.
- Compare the force of friction between “Hard” and “Soft” rolling surfaces.
Technical specifications
- It is constituted of a shaft with a wheel and two disks equipped with rollers, one of the disks turning in an oil bath.
- Five different material blocks are provided as standard (rubber, ferodo, brass, cast iron, nylon).
- These blocks are set under an arm. A mass support hung to the extremity of this arm applies a load on the surface in contact. The friction strength and the friction coefficient are determined by the maximal mass applicable to the wheel to maintain the static balance.
- Two wheels, of which one with a strip rubber, are provided for the study of sliding and rolling resistance.
