弹簧秤
Experiment: Pull items of the same weight but different base area with a spring scale over an identic surface - the tractive force will be the same!
实验:同样的重量,但不同的根据地一个弹簧秤同文面拉项目-牵引力将是相同的!
With the aid of a spring scale (see above) the approximative coefficient of friction between a belt and a specific surface can easy be detected.
随着弹簧规模的援助(见上文)近似一条皮带和一个特定的表面之间的摩擦系数,可以很容易被发现。
