Description

Technical Field

[0001] The utility model relates to the technical field of physical experiments, in particular to a physical measurement dynamometer. Background Art

[0002] At present, tension measurement tests are carried out in physical experiments. A counterweight is installed at the bottom of the dynamometer to measure the value. The dynamometer is divided into spring measurement and electronic measurement. In physical experiments, spring measurement dynamometers are more commonly used. However, the dynamometer is basically handheld, so hand shaking may occur when using it, causing the object to shake. In addition, tension measurements are performed on the object in different directions, resulting in large errors in the physical measurement values. In addition, the dynamometer needs to be held for a long time. When the counterweight is heavy, it will cause arm pain for the user. Utility Model Content
