ABSTRACT:
This invention is a compact and portable apparatus directed toward measuring the coefficients of both static and sliding friction or slip resistance occurring between two surfaces. Means are provided for determining and recording data to establish such friction accurately, repeatably, and in a form suitable for computer entry and data processing. Improvement over the prior art is provided with respect to mechanical configuration, ease of use, plus the acquisition and analysis of data, particularly for conditions involving wet or damp surfaces. A method is disclosed for essentially automatic determination of coefficient of friction.
