摘　　要：利用PASCO物理实验系统对不同材质和半径金属丝用扭摆法测量其切变模量和扭力常数,方法简单,数据可靠,避免了传统实验复杂的安装操作,并方便地利用其已知参数测量任何不规则物体的转动惯量。Using PASCO physics experiment system, the shear modulus and the torsional constant of metal wire with different material and radius were measured by torsional pendulum analysis. This method was simple and reliable. It avoided the complicated installation and operation of traditional experiment. Using the known parameters, the method could be conveniently used to measure the moment of inertia of any irregular objects.
