Abstract
The experiment of granular in rotating cylinder is a common experiment to study granular material behavior. In this study, we investigate the effect of granular type and water content on the dynamic angle of repose in a rotating cylinder. Rice seeds, mung beans, and sand are used as samples. Experimental results show each sample has a different dynamic angle of repose that is related to the shape of the sample. We also study the effect of the water content on the sand sample. The addition of water content has no significant effect on the dynamic angle of repose. This occurs because the water content used has passed the critical point.
