Mechanics experimental instrument of rotation paraboloid

Abstract

The invention discloses a mechanics experimental instrument of rotation paraboloids. The mechanics experimental instrument is used for mechanical rule demonstration for the rotation paraboloids in or after class. Three silvery smooth metal rings of the same material and size sleeve three parabolas made of metal wires respectively and are combined with a motor, so that the stability of objects on the rotation paraboloids is demonstrated, and rules of a liquid differential element in a rotation liquid surface are researched. Compared with the prior art, the experimental instrument has the advantages that f the three metal wire parabolas of different colors are driven by the motor and stable in the rotation speeds, mechanics stability effects of the three metal rings in the three rotation paraboloids can be seen simultaneously, mechanical rules of the liquid differential element in the rotation liquid surface are effectively indirectly demonstrated, and the experimental instrument, as an instrument of demonstrative experiment, is highly inspiring, ingenious in ideals, simple in structure, easy to realize, convenient to operate and obvious in visual effects.

Description

technical field [0001] The patent of the invention relates to a mechanical experiment instrument for demonstrating a rotating paraboloid, and belongs to the field of university physics teaching experiment instruments. Background technique [0002] The concept of rotating paraboloid is often used in college physics courses, such as the reflection law of light under the condition of a parabola, radar reception, and the liquid surface of a rotating liquid is a paraboloid, etc., especially for college students who are beginners in mechanics courses, the liquid surface of a rotating liquid It is difficult to prove the paraboloid, and it is difficult to understand. The inventor of this patent also gave a series of research in the literature [1], which lacks some corresponding demonstration experiments, especially for the liquid elements of the parabolic surface relative to its vicinity. The problem that the liquid is static is difficult to understand. So far, no reliable and credi...

Problems solved by technology

[0002] The concept of rotating paraboloid is often used in college physics courses, such as the reflection law of light under the condition of a parabola, radar reception, and the liquid surface of a rotating liquid is a paraboloid, etc., especially for college students who are beginners in mechanics courses, the liquid surface of a rotating liquid It is difficult to prove the paraboloid, and it is difficult to understand. The inventor of this patent also gave a series of research in the literature [1], which lacks some corresponding demonstration experiments, especially for the liquid elements of the parabolic surface relative to its vicinity. The problem that the liquid is static is difficult to understand. So far, no reliable and credible demonstration experiments have been given on this problem. The problem about the paraboloid is single, and the mechanical stability and stability of the paraboloid have not been observed on the same device. Demonstration of non-stable problems, how to achieve rich demonstration content, obvious visual effects, credible and reliable demonstration experimental equipment, this patent will solve this problem
