THE COEFFICIENTS OF STATIC AND KINETIC FRICTION USING ARDUINO

Rudi Hartono, Eka Cahya Prima

Abstract


The friction coefficient plays an essential role in various aspects of daily life. In transportation safety, the friction coefficient between vehicle tires and the road is critical for safety. In design and construction, friction between structural components contributes to building stability. In industries and machinery, the appropriate friction coefficient between machine parts reduces wear and extends machine life. Therefore, determining the static and kinetic friction coefficients is challenging and requires direct experimental observation of friction. Therefore, a better method is needed to measure the friction coefficient accurately. Several previous studies have been conducted to determine the coefficient of friction using auxiliary tools. The measurement of the friction coefficient using auxiliary tools is indeed necessary to obtain accurate results and save time. It can also avoid misconceptions due to complicated and inefficient manual measurements. In this study, measurement were conducted by pulling a block with a pulley on a flat surface using Arduino Uno and ultrasonic sensor HC-SR04. The research method used in this study is an experiment conducted in the IPSE Chemistry Laboratory. The experimental results show that the static friction coefficient is greater than the kinetic friction coefficient.
