A mechanical comprehensive experimental device and its experimental method

Abstract

The invention discloses a mechanical comprehensive experiment device, which comprises a casing, a top plate, and an experimental carrier plate, the two ends of the experimental carrier plate are respectively hinged with one end of the first support plate and the second support plate, and the first support plate and the second support plate are The other end is respectively equipped with a sixth shaft body and a second shaft body, and the sixth shaft body and the second shaft body can drive the first support plate and the second support plate to exert an upward force on the experimental support plate; Fixed with one end of the tape, the value of L3 can be read through the tape. The invention also discloses an experimental method based on the above experimental device. The invention has comprehensive functions and can carry out various mechanical experiments; the invention can read the size of the soft ruler in real time and provide core values ​​for subsequent mechanical calculations, so that students can conduct in-depth experiments and calculations, and improve the teaching effect. The experimental method of the invention can realize the demonstration of various mechanical phenomena, parameter collection, calculation, etc., and strengthen students' grasp of relevant mechanical knowledge through actual operations, tests, and calculations.

Description

technical field [0001] The invention relates to an experimental device, in particular to a device for mechanical experiments. The present invention also relates to an experimental method based on the above-mentioned experimental device. Background technique [0002] In middle school physics, mechanics is a very important learning content, and the theory, practice and experiment of friction force are very important components of the whole middle school physics. In the study of friction, self-locking is an important phenomenon. The study of self-locking is of great help to understand theories of friction and gravity. [0003] At present, for the teaching of self-locking phenomenon, teachers mostly explain it by combining actual natural phenomena and common sense of life. However, because students' abstraction and association ability are not perfect enough, this leads to students' understanding of self-locking phenomenon. Greater difficulty. [0004] In response to the above...

Problems solved by technology

However, this structure is only suitable for single self-locking studies, and the precision is not high

[0009] Based on the above, the applicant believes that there is currently a lack of relevant data that can be collected to calculate the friction of objects when unlocking, so that students can intuitively understand self-locking and unlocking phenomena, and can also perform related calculations through collected data, and re-cite the theory To practice, improve the teaching effect
