Problems solved by technology

[0002] At present, the teaching equipment in the high school physics laboratory is relatively single, especially for the experimental device of force measurement, which cannot measure force in multiple directions, that is, the pressure and tension in all directions cannot be measured, which directly affects the effect of mechanical experiments.
It reduces the teaching effect of teachers and also affects the learning quality of students. In view of the above defects, an experimental instrument capable of measuring forces in multiple directions is designed to meet the requirements of high school physics course experiments and improve students' learning interest and quality.

Abstract

The invention relates to a spring force measuring device for a mechanics experiment in high school physics and a force measuring method. At present, the teaching tool for a high school physics laboratory is relatively single, especially for the experiment device for force measurement, force measurement in multiple directions can not be done, that is, the pressure and the tension in each directioncan not be measured, and effects of the mechanics experiment are directly influenced. The device comprises a disc (1); the middle part of the disc is provided with a square groove; the square groove is internally provided with a gear (4); the gear is engaged with a rack in a groove rack (3) with a rack; the upper surface and the lower surface of the groove rack are fixed with an upper spring (9) and a lower spring (7); the upper spring and the lower spring are connected with the inner side surface of a support frame (2) and are fixed; the top of the support frame is connected with an upper sliding rod (12); the upper sliding rod sequentially passes through a given-force adjusting sleeve (11) and a zero reset adjusting sleeve (10); and the zero reset adjusting sleeve is connected with the disc through thread. A spring force measuring device for a mechanics experiment in high school physics is provided.
