摘要

The aim of this research is comparison wood-metal load system (experiment 1) and wood-sand load system (experiment 2) to find the static friction coefficient on wood and the effectiveness of both systems. This study used a descriptive quantitative approach by using graphical analysis method, the manipulation variable is the mass of object A (m_A), whereas the response variable is the mass of load (m_L) will move precisely. The result of this study are Wood-sand load system has better accuracy compared to the wood-metal load system, but requires a relatively long time. And from this experiments, it can provide an additional range of static friction coefficients reaching 0.55 using the lower limit in the physics for scientists and engineers textbook is 0.25. So that the range of static friction coefficients of wood-on-wood is 0.25-0.55.
