摘要
在理论上,用2种方法研究了弹簧自重对形变量的影响,并用简单实验对该结论进行了论证,最终得出弹簧自身重力作用产生的形变量为x=G/2k的结论.应用该结论对习题进行了修正.
Two theoretical methods are used to investigate the effects of self-weight on the spring deformation. The results are verified with a simple experiment. The formula of x = G/2k for the spring deformation causes by the spring＇s self-weight is obtained. Using this conclusion, the answers for some problems are corrected.
