Abstract
The invention discloses a magnetic type combined rigid body which comprises a first rigid body and a second rigid body. The first rigid body is a straight rod with mass evenly distributed. The second rigid body is magnetic and movably adsorbed to the first rigid body. The center of mass of the second rigid body is located on the first rigid body. The magnetic type combined rigid body is simple in structure, practical, convenient to use, beneficial to combination of theories and experiments and capable of deepening understanding of the rigid body rotation law.
Description
Technical field
The invention belongs to Experiments of Machanics instrument field, be specially the magnetic-type combination rigid body of a kind of fixed-axis rotation experiment.
Background technology
In College Physics Theory Course, in the time talking about the fixed-axis rotation of rigid body, conventional annulus, disk, straight rod, as rigid model, carry out the analysis and calculation of rigid body fixed-axis rotation rule.Can be obtained by theoretical analysis, same rigid body is in the time of different fixed-axis rotation, and its moment of inertia, rotation period etc. all can change thereupon.But these rigid models used on physical theory class are comparatively single, lack variation, and the change of moment of inertia, rotation period etc. lacks corresponding experimental verification.
Summary of the invention
The technical problem to be solved in the present invention, is that exploitation one can be carried out theory calculating easily, can be advantageously used in again the magnetic-type combination rigid body of experimental verification.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions: a kind of magnetic-type combination rigid body, comprise rigid body first and rigid body second, rigid body first is the equally distributed straight rod of quality, by being made by the magnetic material of attraction; Rigid body second band is magnetic; The activity of rigid body second is adsorbed in rigid body first, and the barycenter of rigid body second is positioned in rigid body first.
Described rigid body second is the equally distributed annulus of quality.
Described rigid body second is the equally distributed disk of quality.
The invention has the beneficial effects as follows: combine because rigid body first and rigid body second adopt magnetic mode, can change easily the relative position of rigid body first and rigid body second, thereby change the moment of inertia of combination rigid body.The upper any point of rigid body first (directly rod) is adsorbed in the magnetic rotating shaft of solid moment of inertia experiment instrument, can carry out easily the theory of rigid body round fixed axis rotation period and moment of inertia calculates and experiment measuring, the theoretical rule of the Rigid Body in Rotation With such as checking parallel axis theorem, it is simple in structure, practical and convenient, be conducive to theoretical combination experiment, deepen the understanding to Rigid Body in Rotation With rule.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is structural representation of the present invention (when rigid body second is annulus).
Fig. 2 is structural representation of the present invention (when rigid body second is disk).
In figure: 1. rigid body first, 2. rigid body second.
Embodiment
As shown in Figure 1, rigid body first 1 is the equally distributed straight rod of quality, by being made by the magnetic material of attraction; Rigid body second 2 is with magnetic annulus for quality is equally distributed, and annulus activity is adsorbed on straight rod, can move up and down along straight rod, and the center of circle of annulus is positioned on straight rod.
As shown in Figure 2, rigid body first 1 is the equally distributed straight rod of quality, by being made by the magnetic material of attraction; Rigid body second 2 is with magnetic disk for quality is equally distributed, and disk activity is adsorbed on straight rod, can move up and down along straight rod, and the center of circle of disk is positioned on straight rod.
