The study of hollow cylinder on inclined plane to determine the cylinder moment of inertia

Abstract

The dynamic motion of cylinder that roll on an inclined plane is an exciting topic, rolling motion is found in landslide phenomena and other rolling phenomena. The cylinder has a variety of diameters including hollow cylinder holes. In this research, the effect of diameter hollow cylinder to the moment of inertia of the cylinder was investigated by rolling the cylinder on the inclined plane. Hole in the center of the cylinder. The ratio between hole diameter and cylinder diameter (η) is an important parameter in this research. Data collection has been done by video recording with a variation of travel distance and angle of the inclined plane. The video was imported into the logger pro software to obtain the traveling time for each case. The experimental results of the moment of inertia were compared to the analytical value. The lowest relative error is 0.13% for the distance variation experiment that was obtained by using η of 0.1011. The moment of inertia is 1912.8 g.cm². The lowest relative error is 0.80% for the angle variation experiment that was obtained by using η of 0.3419. The moment of inertia is 1708.9 g.cm². Hence, the size of the hole diameter is affected by the experimental results for the distance and angle variation.
