Remote digital Young modulus device

Abstract

The invention discloses a remote digital Young modulus device which comprises a Young modulus tester device, an experiment observation device, a camera device, a terminal, a server and a single chip microcomputer. The terminal is connected with the single-chip microcomputer through the server. The camera device is connected with the server; the Young modulus tester device comprises a measuring platform, optical levers are arranged on the two sides of the measuring platform, and a steel wire is hung between the upper ends of the optical levers; the measuring platform is provided with a plane mirror and a groove code. The experiment observation device comprises a movable base, a mounting rod is arranged on the base, a telescope and a scale are arranged on the mounting rod, and a sighting device and a sight bead are arranged on the telescope; and the lower end of the steel wire passes through the groove weight and is connected with an automatic weight adding and reducing device. The Young modulus teaching aid helps students to learn the Young modulus in all directions, and has the advantage of being convenient to observe, measure and record.

Description

technical field [0001] The invention relates to the technical field of teaching, in particular to a remote digital Young's modulus device. Background technique [0002] In the Chinese environment, due to the epidemic, college students are required to study in online courses, and it is difficult to carry out university physics experiment courses. Due to the rapid development of the Internet, laboratories can provide real-time video transmission online, making remote physical experiments possible. The Young's modulus experiment is an important course in university physics experiments. Students are required to master measuring Young's modulus with elongation of wire, measuring minute change in length with optical lever, and processing data with difference-by-difference method. At present, the experimental instruments for measuring the Young's modulus of wires in the university physics laboratory have the following shortcomings: 1. Students cannot see the experimental instrume...

AI Technical Summary

Problems solved by technology

At present, the experimental equipment for measuring the Young's modulus of metal wire in the university physics laboratory has the following disadvantages: 1. Students cannot see the experimental equipment before class, and cannot preview the experimental content

2. It is inconvenient for the teacher to test the experimental results of all students, and it is impossible to judge whether the students have mastered the experimental ability

3. The students got the wrong experimental data in the experiment, and could not make up the test after class
