Friction Apparatus

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. Experiment manual Optional equipment : The unit may be wall mounted or fitted to the Universal Bench Mounting Frame. Dimensions and weight 370 x 240 x 300 mm Net Weight : 14 kg Essential requirements A set of masses.
