True property, hand is passed through into two groups of frosted bars during use, make its it is more firm be held in the hand, while using feel more preferably, with total
When device 1 can be with timing, timer begins to timing when being stretched since spring, and when experiment is stable in one, reaches
One exact value of dynamometry, timer stop timing, are brought great convenience to experimenter, make experiment more meaningful, obtain
Data are more, and the tensile elongation of spring is shown by centimeter scale, save the trouble of later stage measurement, also allow experimenter clearer
Understand the situation of experiment article, while allow experimenter to understand a data more, more meanings, whole device letter are brought to experiment
Single, easy to operate, dynamometry and stable effect are more preferable relative to traditional approach.
