摘要
用扭摆法和三线摆法分别测量圆柱和圆筒的转动惯量。将实验结果与理论值进行比较,发现扭摆法更为精确。并对三线摆误差偏大的原因进行了分析。
Experiments are conducted with torsion pendulum method and three-wire pendulum method respectively for determining the rotational inertia of cylinders.Comparing the experimental data with the theoretical value,it is found that the results obtained by torsion pendulum method are more accurate.The causes of the big error in the three-wire pendulum method are analyzed.
