摘要
研究了钢丝的切变模量随其扭转角度变化而变化的情况,观察到扭转角大于某一角度时,切变模量趋于定值的规律,得出扭摆实验准确测量的方法,此测量方法在其他许多力学实验中也可应用。
The shearing modulus of steel wire changes in accordance with its turning angle. It is observed that when the turning angle is bigger than a certain angle, shearing modulus tends to have a fixed value, thus to obtain a method of accurate measurement of rocking experiment, which can also be applied in many other mechanics experiments.
