Abstract

In pursuit of understanding frictional characteristics of granular materials, this study examined the relationship between sand particle size, specifically the radius, and kinetic frictional force. Experiments were conducted using three sand types with different radii, assessing the force necessary to move a weight at a constant speed across the sand. This investigation aimed to determine how sand radius influences the kinetic friction coefficient, a topic not normally explored before. The expected outcome is that the bigger the sand radius, the greater the dynamic friction coefficient. The result shows that the friction coefficient decreases by increasing of the radius of sand. The findings of this study hold implications for industries such as construction and energy extraction, which heavily rely on understanding frictional behaviors of granular materials. Further investigation is necessary for a comprehensive understanding of these interactions.
