Problems solved by technology

[0003] In current life and work, in learning textbooks, rigid objects will only undergo a small deformation after being stressed, which is difficult to see and feel with the naked eye. It is generally difficult for people to imagine that rigid objects will deform under force, and students also It is difficult to accept the theory that a rigid object is deformed by force, and it is even more difficult to imagine that after a rigid object is deformed by force, an internal force will be generated inside the object

Embodiment 1

[0009] Put the light source 2 on the light source bracket 1, put the reflective panel 3 on the bottom plate 7, then turn on the light source 2, so that the light of the light source 2 hits the 4 points on the plane of the reflective panel 3 at a certain angle, due to the reflection of the light In principle, the reflected light 6 reflected by the reflective panel 3 hits a point on a surface 5, and then, press the mirror surface with a finger or other things, due to the deformation of the rigid mirror surface, the 4 points on the plane change slightly, but the eyes It is not easy to see, but the position where the reflected light 6 hits a point on a surface 5 is greatly shifted and becomes a point at another position. From the offset angle and the change of the position of the reflection point, it can be seen that the rigid object is deformed by force.

Embodiment 2

[0011] Replace the light source 2 with an ordinary flashlight with good condensing performance, and replace the reflective surface 3 with a reflective mirror, then place the small flashlight on the light source bracket 1, put the reflective panel 3 on the bottom plate 7, and then turn on the light source 2 to make the light source The light of 2 hits the 4 points on the plane of the reflective panel 3 at a certain angle. Due to the principle of light reflection, the reflected light 6 reflected by the reflective panel 3 hits a point on one surface 5, and then, with your finger Or other things press the mirror surface, due to the deformation of the rigid mirror surface, the 4 points on the plane change slightly, but the eyes are not easy to see, but the position of the reflected light 6 to a point on a surface 5 is greatly shifted, becomes a point at another location. From the offset angle and the change of the position of the reflection point, it can be seen that the rigid obje...

Embodiment 3

[0013] Replace the light source 2 with a small laser torch, and replace the glossy surface 3 with a reflective mirror, then place the small laser torch on the light source bracket 1, put the reflective panel 3 on the bottom plate 7, and then turn on the light source 2 to make the small laser torch The light hits 4 points on the plane of the reflective panel 3 at a certain angle. Due to the principle of light reflection, the reflected light 6 reflected by the reflective panel 3 hits a point on a surface 5. Then, use your finger or other When something presses the mirror surface, due to the deformation of the rigid mirror surface, the 4 points on the plane change slightly, but the eyes are not easy to see, but the position of the reflected light 6 to a point on a surface 5 is greatly shifted, becoming point at another location. From the offset angle and the change of the position of the reflection point, it can be seen that the rigid object is deformed by force.

Abstract

The invention relates to a device for displaying stress deformation of a rigid object, which is used for amplifying micro deformation of the rigid object through light reflection. In this way, people can easily see and feel the tiny deformation of the rigid object, through the device, people can know that the tiny deformation of the rigid object becomes specific and real, the theory of the tiny deformation of the rigid object can be easily accepted in the learning process, the internal force problem of the rigid object can be better understood, and the learning efficiency is improved. The abstraction theory of teaching is embodied, the theory that rigid objects deform under stress and generate internal force is well accepted, and the abstraction theory learned by students becomes specific and easy. The device is simple in structure, easy and convenient to manufacture, convenient to use and obvious in effect.

Description

technical field [0001] The invention relates to a device for displaying the deformation of rigid objects under force, and more particularly to a device for directly seeing the deformation of rigid objects under force. [0002] technical background [0003] In today's life and work, in learning materials, rigid objects will only deform slightly after being subjected to force, which is difficult to see and feel with the naked eye. It is generally difficult for people to imagine that rigid objects will be deformed under force, and students also It is difficult to accept the theory that rigid objects are deformed by force, and it is even more difficult to imagine that after rigid objects are deformed by force, internal forces are generated inside the object. SUMMARY OF THE INVENTION [0004] In order to solve the above problems, the present invention provides a device that can see the deformation of rigid objects under force. The present invention is achieved in the following ...
