Abstract
This experiment determined the relationship between different volume of granular material filled in a one eighth increment of the diameter and the minimum start angle of a ball on an inclined ramp. The result suggests that there is a relationship between different volume of granular material and the starting angle of the ball. The angle that required to start the ball from rest increased as the material inside decreased. However, when the granular material reached a minimum point, the angle decreased largely. The independent variable was the amount and types of granular materials inside the ball, and the dependent variable was the minimum angle required to start the ball from rest. The result of this study can help determine the stability of a non-filled container.
