Comprehensive designing experiment equipment and method for measuring Young modulus of metal wire

Abstract

The invention relates to comprehensive designing experiment equipment for measuring a Young modulus of a metal wire. The equipment comprises a vertically arranged bracket, a freely suspended metal wire, a micrometer eyepiece, a convex lens and a scale ruler, wherein an upper cross beam is arranged at the upper end of the vertically arranged bracket; the upper end of the freely suspended metal wire is clamped by an upper clamp and fixed on the cross beam; the lower end of the freely suspended metal wire is clamped by a lower clamp and penetrates through a central hole of a platform; the upper clamp and the upper cross beam or the lower clamp and the platform are insulated; the micrometer eyepiece, the convex lens and the scale ruler are used for being used in match with an optical lever; the micrometer eyepiece can be used for watching an image of the scale ruler in a planar reflecting mirror of the optical lever through the convex lens. According to the comprehensive designing experiment equipment and a method for measuring the Young modulus of a metal wire, comprehensive knowledge of relevant courses such as dynamics, optics, electricity and the like is organically combined together, so that a large comprehensive designing experiment which relates to multiple courses and multiple knowledge points and which is used for examining multiple experiment skills and comprehensive knowledge application is designed.

Description

technical field [0001] The invention relates to a physical experiment equipment, in particular to a comprehensively designed experimental equipment and method for measuring the Young's modulus of a metal wire. Background technique [0002] According to the level of experiments, physical experiments can be divided into basic experiments, comprehensive experiments, research experiments, design experiments, etc., among which comprehensive experiments are an indispensable and important part of physical experiments. Comprehensive experiments require comprehensiveness in two aspects: one is to be comprehensive in terms of knowledge points, and the content involves multiple knowledge points in more than two main chapters of a course or the comprehensive knowledge of two or more related courses; It is necessary to be comprehensive in the experimental means. The experimental equipment and experimental means used should include two or more branches of physics. For example, in a compre...
