示教用数显动静态测力仪齐鲁祥，梁志强（山东泰安师专物理系）一、力学测力示教存在的问题中学及大学普物力学教学中，弹力、张力等宏观力的定量示教至今仍是一个没解决好的问题．即使在静平衡情况下，也多是使用沿袭多年根据胡克定律制作的弹簧测力计作些极简单的测量．... Teaching Dynamic Digital Dynamometer QI Lixiang, LIANG Zhiqiang (Shandong Taian Teachers College of Physics) First, the problem of mechanical force measurement teaching Middle school and college general mechanics teaching, elasticity, tension and other macro-quantitative indicators Teaching is still a problem that has not been solved yet. Even in the case of static equilibrium, it is often done with some very simple measurements using spring-force dynamometers that have been built according to Hooke’s law for many years. ...
