Experimental Characteristics on the Number of Spin Reversals of Semi-ellipsoidal Shaped Celts with Various Principal Curvatures -Trajectory Tracking in Moving ImagesKazumasa KIOI ABSTRACT The authors have studied on experimental characteristics for the number of spin reversals of semiellipsoidal celts with various principal curvatures. Using rods and weights, the average number of spin reversals was recorded more than five times. Using only weights, we found experimental conditions showing nine spin reversals. It may be a world record for the number of spin reversals of celt with a symmetric shape.
